The State of the Ocean Report aims to stimulate research and policy actions towards ‘the ocean we need for the future we want’. | |||
The reports contribute to sustainable development goals as well as other global processes such as the UNFCCC climate efforts, the Convention on Biological Diversity and Disaster Risk Reduction. | |||
Structured around the seven UN Decade of Ocean Science for Sustainable Development Outcomes, the Report provides important information about the achievement of the UN Ocean Decade objectives and, in the longer term, about ocean well-being. | |||
More than 100 authors from 28 countries contributed to the Report. The different sections provide insights on ocean-related scientific activities and analyses describing the current and future state of the ocean, addressing physical, chemical, ecological, socio-economic and governance aspects. | |||

''The Outlaw Ocean Project produces investigative stories about human rights, labor, and environmental concerns on the two thirds of the planet covered by water.'' | |||
''More than 50 million people work offshore. Roughly 80 percent of the goods we consume reach us by way of the sea. Half the air we breathe comes from the oceans. And yet, this realm is home to a variety of urgent concerns that go largely overlooked by most news outlets because it is too costly, too dangerous and too time consuming to report on them. These concerns include the murder of stowaways, arms trafficking, illegal fishing, pollution, dumping, drilling and human slavery on fishing ships. The organization was founded and is directed by Ian Urbina, who produced an award-winning series in 2015 in The New York Times and a subsequent best-selling book in 2019.'' | |||
''The Outlaw Ocean Project’s journalism is distinct not just in its focus, but also in how the reporting is conducted and distributed. Most of the stories are reported at least partially at sea. In the United States, the non-profit publishes its stories in various news outlets, including the New Yorker, NBC News, The Atlantic and The Washington Post. The reporting is also translated into a half dozen languages and further disseminated abroad in partnership with dozens of foreign newspapers, magazines, radio and television venues.'' | |||

''After two decades of planning and talks that culminated in a grueling race over the past few days in New York, a significant majority of nations agreed on language for a historic United Nations treaty that would protect ocean biodiversity.'' | |||
''As marine life faces threats from climate change, overfishing, the possibility of seabed mining and other dangers, the treaty would make it possible to create marine-protected areas and enact other conservation measures on the “high seas,” the immense expanse of ocean covering almost half the world.'' | |||
''“Today the world came together to protect the ocean for the benefit of our children and grandchildren,” said Monica Medina, an assistant secretary of state. “We leave here with the ability to create protected areas in the high seas and achieve the ambitious goal of conserving 30 percent of the ocean by 2030.”'' | |||
<big><big>'''Nations Agree on Language for Historic Treaty to Protect Ocean Life'''</big></big> | |||
GreenPolicy360: This is historic and a foundation of legal agreement to build on... The text of the High Seas agreement comes after decades of geopolitical negotiating over ocean resources, rights and responsibilities of nations to the protection of oceans and ocean life, and now moves on to the realities of legal enforcement of promises/pledges that have now been memorialized. | |||
<big>'''Nations agree on ‘world-changing’ deal to protect ocean life'''</big> | |||
''More than 190 countries have reached a landmark deal for protecting the biodiversity of the world’s oceans, agreeing for the first time on a common framework for establishing new protected areas in international waters.'' | |||
* https://www.washingtonpost.com/climate-environment/2023/03/05/un-ocean-treaty-high-seas/ | |||

Nichola Clark: “a once-in-a-generation opportunity to protect the oceans — a major win for biodiversity.” | |||
* https://apnews.com/article/un-oceans-biodiversity-treaty-0b024fa07e8c1947236d8b8491ebf92c | |||
''The treaty will create a new body to manage conservation of ocean life and establish marine protected areas in the high seas. Clark said that’s critical to achieve the U.N. Biodiversity Conference’s recent pledge to protect 30% of the planet’s waters, as well as its land, for conservation.'' | |||
''Treaty negotiations initially were anticipated to conclude Friday (March 3), but stretched through the night and deep into Saturday. The crafting of the treaty, which at times looked in jeopardy, represents “a historic and overwhelming success for international marine protection,” said Steffi Lemke, Germany’s environment minister.'' | |||
(Note from GreenPolicy360: Lemke is a member of the German Green Party and one of the co-founders of the Green Party in the GDR in 1989... see more about the Greens, Bündnis 90/Die Grünen who hold a number of top positions in the current German government -- https://en.wikipedia.org/wiki/Alliance_90/The_Greens) | |||
''“For the first time, we are getting a binding agreement for the high seas, which until now have hardly been protected,” Lemke said. “Comprehensive protection of endangered species and habitats is now finally possible on more than 40% of the Earth’s surface.”'' | |||
''The question now is how well the ambitious treaty will be implemented.'' | |||
''Formal adoption also remains outstanding, with numerous conservationists and environmental groups vowing to watch closely.'' | |||
''The high seas have long suffered exploitation due to commercial fishing and mining, as well as pollution from chemicals and plastics. The new agreement is about “acknowledging that the ocean is not a limitless resource, and it requires global cooperation to use the ocean sustainably...”'' | |||

''We congratulate the President of the Intergovernmental Conference on Marine Biodiversity of Areas Beyond National Jurisdiction, the secretariat of the UN, and all the state delegates for their efforts.'' | |||
''“The High Seas Treaty opens the path for humankind to finally provide protection to marine life across vast swathes of the ocean. Its adoption will close a significant gap in international law and offer a framework for governments to work together to protect global ocean heath, climate resilience, and the socioeconomic wellbeing and food security of billions of people. We stand ready to support its implementation,” says IUCN Director General, Dr Bruno Oberle.'' | |||
''Although more ambitious measures will be needed, this legally-binding agreement marks an important step towards protecting the two-thirds of the ocean that lies beyond national jurisdiction.'' | |||
''IUCN particularly applauds the alignment of the Treaty with other international commitments including the Kunming-Montreal Global Biodiversity Framework, and the creation of a special fund to finance the rehabilitation and ecological restoration of marine biodiversity.'' | |||
''IUCN and its Members have been advocating for such an agreement for two decades and have been providing scientific and legal advice to negotiators since the start of the formal negotiations (in 2018), in particular on provisions concerning area-based management tools, especially marine protected areas. Commitments must now be implemented in ways that help address climate change and the many threats to marine ecosystems, and guarantee the critical benefits marine ecosystems provide to people.'' | |||
''IUCN is calling for adoption and ratification to be fast-tracked, to bring the High Seas Treaty into force. The Union is offering its continued support to Parties and stakeholders to lay the foundation for a rapid, effective, and equitable implementation.'' | |||

'''''To mobilize action, the Conference will seek to propel much needed science-based innovative solutions aimed at starting a new chapter of global ocean action.''''' | |||
''About the 2022 UN Ocean Conference'' | |||
''The ocean covers 70 percent of the Earth’s surface, is the planet's largest biosphere, and is home to up to 80 percent of all life in the world. It generates 50 percent of the oxygen we need, absorbs 25 percent of all carbon dioxide emissions and captures 90 percent of the additional heat generated from those emissions. It is not just ‘the lungs of the planet’ but also its largest carbon sink - a vital buffer against the impacts of climate change.'' | |||
''It nurtures unimaginable biodiversity and produces food, jobs, mineral and energy resources needed for life on the planet to survive and thrive. There is a great deal we still do not know about the ocean but there are many reasons why we need to manage it sustainably - as set out in the targets of Sustainable Development Goal 14: Life Below Water.'' | |||
''The science is clear – the ocean is facing unprecedented threats as a result of human activities. Its health and ability to sustain life will only get worse as the world population grows and human activities increase. If we want to address some of the most defining issues of our time such as climate change, food insecurity, diseases and pandemics, diminishing biodiversity, economic inequality and even conflicts and strife, we must act now to protect the state of our ocean.'' | |||
<big>'''''Oceans at Risk'''''</big> | |||
''A sobering new international report highlights the critical state of the world's increasingly polluted oceans and the threat that degradation poses to life in the seas and the humans who depend on it.'' | |||
''It's a chilling and exhaustive summation, just published in [https://www.annalsofglobalhealth.org/articles/10.5334/aogh.2831/ Annals of Global Health] and it begins this way:'' | |||
''The oceans are vast. They cover more than 70% of the earth’s surface, hold 97% of the world’s water, host some of the planet’s most diverse ecosystems, and support economies in countries around the world. Microscopic organisms in the seas are a major source of atmospheric oxygen. By absorbing more than 90% of the excess heat released into the earth’s environment and nearly one-third of carbon dioxide emissions, the oceans slow planetary warming and stabilize the global climate.'' | |||
''The oceans are essential to human health and well-being. They provide food to billions, livelihoods for millions and are the source of multiple essential medicines. They have traditional cultural value and are a source of joy, beauty, peace, and recreation. The oceans are particularly important to the health and well-being of people in small island nations, the high Arctic, and coastal communities, especially those in the Global South. The very survival of these vulnerable populations depends on the health of the seas.'' | |||
''Despite their vast size, the oceans are under threat, and human activity is the main source of the threat. Climate change and other environmental disruptions of human origin have caused sea surface temperatures to rise, glaciers to melt, and harmful algal species and pathogenic bacteria to migrate into waters that were previously uncontaminated. Rising seas and increasingly violent coastal storms endanger the 600 million people worldwide who live within 10 m of sea level. Rising concentrations of atmospheric CO2 have caused acidification of the oceans, which in turn destroys coral reefs, impairs development of oysters and other shellfish, and dissolves calcium-containing microorganisms at the base of the food web. The oceans are losing oxygen. Fish stocks are declining. Dredging, mechanized trawling, oil exploration, and planned deep undersea metal mining threaten the seabeds.'' | |||
''Pollution – unwanted, often hazardous waste material released into the environment by human activity – is one of the existential challenges of the present age. Like climate change, biodiversity loss, and depletion of the world’s fresh water supply, pollution endangers the stability of the earth’s support systems and threatens the continuing survival of human societies.'' | |||
'''''"Pollution endangers the stability of the earth’s support systems and threatens the continuing survival of human societies"''''' | |||
'''''Oceans in peril, humans at risk; Widespread ocean pollution threatens the health of more than 3 billion people''''' | |||
''Ocean pollution is widespread and getting worse, and when toxins in the oceans make landfall they imperil the health and well-being of more than 3 billion people, according to a new report by an international coalition of scientists led by Boston College’s Global Observatory on Pollution on Health and the Centre Scientifique de Monaco.'' | |||
''Atop the proposals to remediate ocean pollution, the researchers recommend: banning coal combustion and the production of single-use plastics, controlling coastal pollution, and expanding marine protected areas.'' | |||
''The study is the first comprehensive examination of the impacts of ocean pollution on human health. It was published in the online edition of the Annals of Global Health and released at the Monaco International Symposium on Human Health & the Ocean in a Changing World.'' | |||
''“Simply put: Ocean pollution is a major global problem, it is growing, and it directly affects human health,” said Professor Philip Landrigan, M.D., the director of the observatory and of BC’s Global Public Health and the Common Good Program. “People have heard about plastic pollution in the oceans, but that is only part of it. Research shows the oceans are being fouled by a complex stew of toxins including mercury, pesticides, industrial chemicals, petroleum wastes, agricultural runoff, and manufactured chemicals embedded in plastic. These toxic materials in the ocean get into people, mainly by eating contaminated seafood."'' | |||
''“We are all at risk, but the people most seriously affected are people in coastal fishing communities, people on small island nations, indigenous populations and people in the high Arctic. The very survival of these vulnerable populations depends on the health of the seas.”'' | |||
''The oceans cover more than 70 percent of the earth’s surface. Despite their vast size, the seas are under threat, primarily as a result of human activity, according to the findings, drawn from 584 scientific reports, which detail:'' | |||
''Pollution of the oceans by plastics, toxic metals, manufactured chemicals, pesticides, sewage, and agricultural runoff is killing and contaminating the fish that feed 3 billion people.'' | |||
''Coastal pollution spreads life-threatening infections. | |||
Oil spills and chemical wastes threaten the microorganisms in the seas that provide much of the world’s oxygen supply.'' | |||
'''''Mobilize global resolve to curb ocean pollution''''' | |||
''“The link between ocean pollution and human health has, for a long time, given rise to very few studies,” Prince Albert wrote in an introduction to the report. “Taking into account the effects of ocean pollution – due to plastic, water and industrial waste, chemicals, hydrocarbons, to name a few – on human health should mean that this threat must be permanently included in the international scientific activity.'' | |||
''“This document on Human Health and the Ocean, prepared with the contributions of the Monaco Science Centre and Boston College, substantiates that pollution of the Ocean is not inevitable”...'' | |||
'''''Among the key findings:''''' | |||
''Mercury pollution has become widespread in the oceans, accumulating to high levels in predator fish and once in the food chain poses documented risks to infants, children and adults.'' | |||
''Coal is the major source of mercury pollution, its toxins vaporizing into the air as it burns and eventually washing into the oceans.'' | |||
''Pollution along the coasts by industrial waste, agricultural runoff, pesticides, and human sewage has increased the frequency of Harmful Algal Blooms (HABs) producing toxins associated with dementia, amnesia, neurological damage, and rapid death.'' | |||
''Plastic waste – entering the oceans at a rate of more than 10 million tons each year – kills seabirds and fish and is consumed by humans in the form of toxic microscopic particles, now found in all humans. | |||
The waters most seriously impacted by ocean pollution are the Mediterranean Sea, the Baltic Sea, and Asian rivers.'' | |||

''Plastic pollution is suffocating our ocean and the many animals that call it home. Researchers estimate there are now over 5.25 trillion pieces of plastic in the ocean with 8.75 million metric tons being added every year. This pollution is impacting our marine ecosystems and wildlife including seabirds, dolphins, fish, turtles, and whales. Plastic fragments are even displacing plankton as the base of the food chain. So what’s the best way to combat this global epidemic facing our ocean? It’s simple: we need to stop the problem at the source! The Surfrider Foundation’s Ocean Friendly Restaurants program does just that. One restaurant, one customer at a time, it increases awareness, drives behavior change, and ultimately creates scalable impact to reduce our plastic footprint.'' | |||
''Researchers estimate there are now over 5.25 trillion pieces of plastic in the ocean with the number continuing to grow every day.'' | |||
''An estimated 100 billion plastic bags are used ANNUALLY in the United States.'' | |||
''49.4 billion plastic water bottles were sold in one year’s time with only 31.1% recycled, leaving roughly 34 billion plastic bottles that were littered or went into a landfill in 2015.'' | |||
''Restaurants use an average of 5,800 gallons of water per day'' | |||
''Plastic does not biodegrade so virtually every piece of plastic ever created still exists in some form today!'' | |||

Via Science / July 2015 | |||
Although the ocean moderates anthropogenic climate change, this has great impacts on its fundamental physics and chemistry, with important consequences for ecosystems and people. | ''Although the ocean moderates anthropogenic climate change, this has great impacts on its fundamental physics and chemistry, with important consequences for ecosystems and people. Despite the ocean’s critical role in regulating climate—and providing food security and livelihoods for millions of people—international climate negotiations have only minimally considered impacts on the ocean. Here, we evaluate changes to the ocean and its ecosystems, as well as to the goods and services they provide, under two contrasting CO2 scenarios: the current high-emissions trajectory (Representative Concentration Pathway 8.5, RCP8.5) and a stringent emissions scenario (RCP2.6) consistent with the Copenhagen Accord of keeping mean global temperature increase below 2°C in the 21st century. To do this, we draw on the consensus science in the latest assessment report of the Intergovernmental Panel on Climate Change and papers published since the assessment.'' | ||
Warming and acidification of surface ocean waters will increase proportionately with cumulative CO2 emissions (see figure). Warm-water corals have already been affected, as have mid-latitude seagrass, high-latitude pteropods and krill, mid-latitude bivalves, and fin fishes. Even under the stringent emissions scenario (RCP2.6), warm-water corals and mid-latitude bivalves will be at high risk by 2100. Under our current rate of emissions, most marine organisms evaluated will have very high risk of impacts by 2100 and many by 2050. These results—derived from experiments, field observations, and modeling—are consistent with evidence from high-CO2 periods in the paleorecord. | '''''Warming and acidification of surface ocean waters''''' ''will increase proportionately with cumulative CO2 emissions (see figure).

Impacts to the ocean’s ecosystem services follow a parallel trajectory. Services such as coastal protection and capture fisheries are already affected by ocean warming and acidification. The risks of impacts to these services increase with continued emissions: They are predicted to remain moderate for the next 85 years for most services under stringent emission reductions, but the business-as-usual scenario (RCP8.5) would put all ecosystem services we considered at high or very high risk over the same time frame. These impacts will be cumulative or synergistic with other human impacts, such as overexploitation of living resources, habitat destruction, and pollution. Fin fisheries at low latitudes, which are a key source of protein and income for millions of people, will be at high risk. | ''Impacts to the ocean’s ecosystem services follow a parallel trajectory.

The risks of impacts to these services increase with continued emissions: They are predicted to remain moderate for the next 85 years for most services under stringent emission reductions, but the business-as-usual scenario (RCP8.5) would put all ecosystem services we considered at high or very high risk over the same time frame. These impacts will be cumulative or synergistic with other human impacts, such as overexploitation of living resources, habitat destruction, and pollution. Fin fisheries at low latitudes, which are a key source of protein and income for millions of people, will be at high risk.'' | ||
Four key messages emerge. First, the ocean strongly influences the climate system and provides important services to humans. Second, impacts on key marine and coastal organisms, ecosystems, and services are already detectable, and several will face high risk of impacts well before 2100, even under the low-emissions scenario (RCP2.6). These impacts will occur across all latitudes, making this a global concern beyond the north/south divide. Third, immediate and substantial reduction of CO2 emissions is required to prevent the massive and mostly irreversible impacts on ocean ecosystems and their services that are projected with emissions greater than those in RCP2.6. Limiting emissions to this level is necessary to meet stated objectives of the United Nations Framework Convention on Climate Change; a substantially different ocean would result from any less-stringent emissions scenario. Fourth, as atmospheric CO2 increases, protection, adaptation, and repair options for the ocean become fewer and less effective. | ''Four key messages emerge.

''A new NASA study of ocean temperature measurements shows in recent years extra heat from greenhouse gases has been trapped in the waters of the Pacific and Indian oceans.

''Researchers from NASA’s Jet Propulsion Laboratory (JPL), Pasadena, California, found a specific layer of the Indian and Pacific oceans between 300 and 1,000 feet (100 and 300 meters) below the surface has been accumulating more heat than previously recognized. They also found the movement of warm water has affected surface temperatures. The result was published Thursday in the journal Science...'' | |||

The Pacific Ocean is the primary source of the subsurface warm water found in the study, though some of that water now has been pushed to the Indian Ocean.

''This '''interactive web tool''' – currently in prototype stage – is being built to enable anyone to visualize the global fishing fleet in space and time. Global Fishing Watch will reveal the intensity of fishing effort around the world, one of the stressors contributing to the precipitous decline of our fisheries.'' | |||
''With hundreds of millions of people around the world depending on our ocean for their livelihoods, and many more relying on the ocean for food, ensuring the long-term sustainability of our ocean is a critical global priority.

'''''Global Fishing Watch will be available to the public, enabling anyone with an internet connection to monitor when and where commercial fishing is happening around the globe.''''' | |||
''Citizens can use the tool to see for themselves whether their fisheries are being effectively managed. Seafood suppliers can keep tabs on the boats they buy fish from. Media and the public can act as watchdogs to improve the sustainable management of global fisheries. Fisherman can show that they are obeying the law and doing their part. Researchers will have access to a multi-year record of all trackable fishing activity.'' | |||
''The tool uses a global feed of vessel locations extracted from Automatic Identification System (AIS) tracking data collected by satellite, revealing the movement of vessels over time. The system automatically classifies the observed patterns of movement as either “fishing” or “non-fishing” activity.'' | |||
''This version of the Global Fishing Watch started with 3.7 billion data points, more than a terabyte of data from two years of satellite collection, covering the movements of 111,374 vessels during 2012 and 2013. We ran a behavioral classification model that we developed across this data set to identify when and where fishing behavior occurred. The prototype visualization contains 300 million AIS data points covering over 25,000 unique vessels. For the initial fishing activity map, the data is limited to 35 million detections from 3,125 vessels that we were able to independently verify were fishing vessels. Global Fishing Watch then displays fishing effort in terms of the number of hours each vessel spent engaged in fishing behavior, and puts it all on a map that anyone with a web browser will be able to explore.'' | |||

State of the Ocean
The State of the Ocean Report aims to stimulate research and policy actions towards ‘the ocean we need for the future we want’.
The reports contribute to sustainable development goals as well as other global processes such as the UNFCCC climate efforts, the Convention on Biological Diversity and Disaster Risk Reduction.
Structured around the seven UN Decade of Ocean Science for Sustainable Development Outcomes, the Report provides important information about the achievement of the UN Ocean Decade objectives and, in the longer term, about ocean well-being.
More than 100 authors from 28 countries contributed to the Report. The different sections provide insights on ocean-related scientific activities and analyses describing the current and future state of the ocean, addressing physical, chemical, ecological, socio-economic and governance aspects.

The Outlaw Ocean Project
- with Ian Urbina https://twitter.com/ian_urbina/ | https://linktr.ee/ian_urbina
The Outlaw Ocean Project produces investigative stories about human rights, labor, and environmental concerns on the two thirds of the planet covered by water.
More than 50 million people work offshore. Roughly 80 percent of the goods we consume reach us by way of the sea. Half the air we breathe comes from the oceans. And yet, this realm is home to a variety of urgent concerns that go largely overlooked by most news outlets because it is too costly, too dangerous and too time consuming to report on them. These concerns include the murder of stowaways, arms trafficking, illegal fishing, pollution, dumping, drilling and human slavery on fishing ships. The organization was founded and is directed by Ian Urbina, who produced an award-winning series in 2015 in The New York Times and a subsequent best-selling book in 2019.
The Outlaw Ocean Project’s journalism is distinct not just in its focus, but also in how the reporting is conducted and distributed. Most of the stories are reported at least partially at sea. In the United States, the non-profit publishes its stories in various news outlets, including the New Yorker, NBC News, The Atlantic and The Washington Post. The reporting is also translated into a half dozen languages and further disseminated abroad in partnership with dozens of foreign newspapers, magazines, radio and television venues.

Nations Agree on Language for Historic Treaty to Protect Ocean Life
- The United Nations agreement is a significant step toward protecting biodiversity under growing threat from climate change, overfishing and seabed mining
March 4, 2023
After two decades of planning and talks that culminated in a grueling race over the past few days in New York, a significant majority of nations agreed on language for a historic United Nations treaty that would protect ocean biodiversity.
As marine life faces threats from climate change, overfishing, the possibility of seabed mining and other dangers, the treaty would make it possible to create marine-protected areas and enact other conservation measures on the “high seas,” the immense expanse of ocean covering almost half the world.
“Today the world came together to protect the ocean for the benefit of our children and grandchildren,” said Monica Medina, an assistant secretary of state. “We leave here with the ability to create protected areas in the high seas and achieve the ambitious goal of conserving 30 percent of the ocean by 2030.”
Nations Agree on Language for Historic Treaty to Protect Ocean Life
GreenPolicy360: This is historic and a foundation of legal agreement to build on... The text of the High Seas agreement comes after decades of geopolitical negotiating over ocean resources, rights and responsibilities of nations to the protection of oceans and ocean life, and now moves on to the realities of legal enforcement of promises/pledges that have now been memorialized.
Nations agree on ‘world-changing’ deal to protect ocean life
More than 190 countries have reached a landmark deal for protecting the biodiversity of the world’s oceans, agreeing for the first time on a common framework for establishing new protected areas in international waters.
Via the Associated Press
Nichola Clark: “a once-in-a-generation opportunity to protect the oceans — a major win for biodiversity.”
The treaty will create a new body to manage conservation of ocean life and establish marine protected areas in the high seas. Clark said that’s critical to achieve the U.N. Biodiversity Conference’s recent pledge to protect 30% of the planet’s waters, as well as its land, for conservation.
Treaty negotiations initially were anticipated to conclude Friday (March 3), but stretched through the night and deep into Saturday. The crafting of the treaty, which at times looked in jeopardy, represents “a historic and overwhelming success for international marine protection,” said Steffi Lemke, Germany’s environment minister.
(Note from GreenPolicy360: Lemke is a member of the German Green Party and one of the co-founders of the Green Party in the GDR in 1989... see more about the Greens, Bündnis 90/Die Grünen who hold a number of top positions in the current German government -- https://en.wikipedia.org/wiki/Alliance_90/The_Greens)
“For the first time, we are getting a binding agreement for the high seas, which until now have hardly been protected,” Lemke said. “Comprehensive protection of endangered species and habitats is now finally possible on more than 40% of the Earth’s surface.”
The question now is how well the ambitious treaty will be implemented.
Formal adoption also remains outstanding, with numerous conservationists and environmental groups vowing to watch closely.
The high seas have long suffered exploitation due to commercial fishing and mining, as well as pollution from chemicals and plastics. The new agreement is about “acknowledging that the ocean is not a limitless resource, and it requires global cooperation to use the ocean sustainably...”
Via ICUN.org
International Union for Conservation of Nature
We congratulate the President of the Intergovernmental Conference on Marine Biodiversity of Areas Beyond National Jurisdiction, the secretariat of the UN, and all the state delegates for their efforts.
“The High Seas Treaty opens the path for humankind to finally provide protection to marine life across vast swathes of the ocean. Its adoption will close a significant gap in international law and offer a framework for governments to work together to protect global ocean heath, climate resilience, and the socioeconomic wellbeing and food security of billions of people. We stand ready to support its implementation,” says IUCN Director General, Dr Bruno Oberle.
Although more ambitious measures will be needed, this legally-binding agreement marks an important step towards protecting the two-thirds of the ocean that lies beyond national jurisdiction.
IUCN particularly applauds the alignment of the Treaty with other international commitments including the Kunming-Montreal Global Biodiversity Framework, and the creation of a special fund to finance the rehabilitation and ecological restoration of marine biodiversity.
IUCN and its Members have been advocating for such an agreement for two decades and have been providing scientific and legal advice to negotiators since the start of the formal negotiations (in 2018), in particular on provisions concerning area-based management tools, especially marine protected areas. Commitments must now be implemented in ways that help address climate change and the many threats to marine ecosystems, and guarantee the critical benefits marine ecosystems provide to people.
IUCN is calling for adoption and ratification to be fast-tracked, to bring the High Seas Treaty into force. The Union is offering its continued support to Parties and stakeholders to lay the foundation for a rapid, effective, and equitable implementation.

GreenPolicy360: Environmental Law Takes Precedent-Setting Legal Step after Decades of Negotiations
Future generations will look back this High Seas Treaty and ask why it took so long
We ask it's time 'to get to work' with enforcement, there is no time for delay
The agreement comes 41 years after Ambassador Tommy Koh served as President of the Third UN Conference on the Law of the Sea (known as resolution 2340 (XXII) of 18 December 1967), which led to the United Nations Convention on the Laws of the Sea and now another Singapore Ambassador, Rena Lee, has presided over successful negotiations on the UN high seas treaty.
Here are links to the legal documents: Intergovernmental conference on an international legally binding instrument under the United Nations Convention on the Law of the Sea on the conservation and sustainable use of marine biological diversity of areas beyond national jurisdiction
Fifth session
New York, 20 February – 3 March 2023
Further refreshed draft text of an agreement under the United Nations Convention on the Law of the Sea on the conservation and sustainable use of marine biological diversity of areas beyond national jurisdiction
UN Secretary General António Guterres said on the landmark treaty:
"Our ocean has been under pressure for decades. We can no longer ignore the ocean emergency. In adopting a robust and ambitious agreement at this meeting, you can take an important step forward in countering these destructive trends and advancing ocean health for generations to come. This treaty can ensure the conservation and sustainable use of marine biological diversity of over two-thirds of our life-sustaining ocean space."
UN Ambassador for the Oceans and Law of the Sea Issues Rena Lee said:
"Yesterday I mentioned the way forward, we have finish the text of the agreement. We will run through the text for technical edits. The text will then be translated into all six language versions and time to be specified. We will then formally adopt the text in all six official languages of the United Nations."
There are five main elements to the High Seas Treaty:
'Marine Protected Areas (MPAs)
High seas ecosystems, critical to the continuation of life in the ocean, are conserved by the establishment of fully protected, well-managed networks of marine protected areas.
Environmental Impact Assessments (EIAs)
Any proposed activity on the high seas that may negatively affect marine life is prematurely evaluated by scientists and relevant stakeholders.
Access & Benefit Sharing of Marine Genetic Resources
Developing nations have access to, and are able to benefit from, biological genetic materials discovered on the high seas.
Capacity-Building & Marine Technology Transfer
Developing nations have the capacity, technology, and educational/research opportunities necessary to participate in deep sea science.
Cross-cutting Issues
These are issues that affect a number of elements and are integrated throughout the new agreement.

United Nations Oceans Conference
5 Actions You can Take to #SaveOurOcean
To mobilize action, the Conference will seek to propel much needed science-based innovative solutions aimed at starting a new chapter of global ocean action.
About the 2022 UN Ocean Conference
The ocean covers 70 percent of the Earth’s surface, is the planet's largest biosphere, and is home to up to 80 percent of all life in the world. It generates 50 percent of the oxygen we need, absorbs 25 percent of all carbon dioxide emissions and captures 90 percent of the additional heat generated from those emissions. It is not just ‘the lungs of the planet’ but also its largest carbon sink - a vital buffer against the impacts of climate change.
It nurtures unimaginable biodiversity and produces food, jobs, mineral and energy resources needed for life on the planet to survive and thrive. There is a great deal we still do not know about the ocean but there are many reasons why we need to manage it sustainably - as set out in the targets of Sustainable Development Goal 14: Life Below Water.
The science is clear – the ocean is facing unprecedented threats as a result of human activities. Its health and ability to sustain life will only get worse as the world population grows and human activities increase. If we want to address some of the most defining issues of our time such as climate change, food insecurity, diseases and pandemics, diminishing biodiversity, economic inequality and even conflicts and strife, we must act now to protect the state of our ocean.
Oceans at Risk
A sobering new international report highlights the critical state of the world's increasingly polluted oceans and the threat that degradation poses to life in the seas and the humans who depend on it.
It's a chilling and exhaustive summation, just published in Annals of Global Health and it begins this way:
The oceans are vast. They cover more than 70% of the earth’s surface, hold 97% of the world’s water, host some of the planet’s most diverse ecosystems, and support economies in countries around the world. Microscopic organisms in the seas are a major source of atmospheric oxygen. By absorbing more than 90% of the excess heat released into the earth’s environment and nearly one-third of carbon dioxide emissions, the oceans slow planetary warming and stabilize the global climate.
The oceans are essential to human health and well-being. They provide food to billions, livelihoods for millions and are the source of multiple essential medicines. They have traditional cultural value and are a source of joy, beauty, peace, and recreation. The oceans are particularly important to the health and well-being of people in small island nations, the high Arctic, and coastal communities, especially those in the Global South. The very survival of these vulnerable populations depends on the health of the seas.
Despite their vast size, the oceans are under threat, and human activity is the main source of the threat. Climate change and other environmental disruptions of human origin have caused sea surface temperatures to rise, glaciers to melt, and harmful algal species and pathogenic bacteria to migrate into waters that were previously uncontaminated. Rising seas and increasingly violent coastal storms endanger the 600 million people worldwide who live within 10 m of sea level. Rising concentrations of atmospheric CO2 have caused acidification of the oceans, which in turn destroys coral reefs, impairs development of oysters and other shellfish, and dissolves calcium-containing microorganisms at the base of the food web. The oceans are losing oxygen. Fish stocks are declining. Dredging, mechanized trawling, oil exploration, and planned deep undersea metal mining threaten the seabeds.
Pollution – unwanted, often hazardous waste material released into the environment by human activity – is one of the existential challenges of the present age. Like climate change, biodiversity loss, and depletion of the world’s fresh water supply, pollution endangers the stability of the earth’s support systems and threatens the continuing survival of human societies.
"Pollution endangers the stability of the earth’s support systems and threatens the continuing survival of human societies"
Oceans in peril, humans at risk; Widespread ocean pollution threatens the health of more than 3 billion people
Ocean pollution is widespread and getting worse, and when toxins in the oceans make landfall they imperil the health and well-being of more than 3 billion people, according to a new report by an international coalition of scientists led by Boston College’s Global Observatory on Pollution on Health and the Centre Scientifique de Monaco.
Atop the proposals to remediate ocean pollution, the researchers recommend: banning coal combustion and the production of single-use plastics, controlling coastal pollution, and expanding marine protected areas.
The study is the first comprehensive examination of the impacts of ocean pollution on human health. It was published in the online edition of the Annals of Global Health and released at the Monaco International Symposium on Human Health & the Ocean in a Changing World.
“Simply put: Ocean pollution is a major global problem, it is growing, and it directly affects human health,” said Professor Philip Landrigan, M.D., the director of the observatory and of BC’s Global Public Health and the Common Good Program. “People have heard about plastic pollution in the oceans, but that is only part of it. Research shows the oceans are being fouled by a complex stew of toxins including mercury, pesticides, industrial chemicals, petroleum wastes, agricultural runoff, and manufactured chemicals embedded in plastic. These toxic materials in the ocean get into people, mainly by eating contaminated seafood."
“We are all at risk, but the people most seriously affected are people in coastal fishing communities, people on small island nations, indigenous populations and people in the high Arctic. The very survival of these vulnerable populations depends on the health of the seas.”
The oceans cover more than 70 percent of the earth’s surface. Despite their vast size, the seas are under threat, primarily as a result of human activity, according to the findings, drawn from 584 scientific reports, which detail:
Pollution of the oceans by plastics, toxic metals, manufactured chemicals, pesticides, sewage, and agricultural runoff is killing and contaminating the fish that feed 3 billion people.
Coastal pollution spreads life-threatening infections. Oil spills and chemical wastes threaten the microorganisms in the seas that provide much of the world’s oxygen supply.
Mobilize global resolve to curb ocean pollution
“The link between ocean pollution and human health has, for a long time, given rise to very few studies,” Prince Albert wrote in an introduction to the report. “Taking into account the effects of ocean pollution – due to plastic, water and industrial waste, chemicals, hydrocarbons, to name a few – on human health should mean that this threat must be permanently included in the international scientific activity.
“This document on Human Health and the Ocean, prepared with the contributions of the Monaco Science Centre and Boston College, substantiates that pollution of the Ocean is not inevitable”...
Among the key findings:
Mercury pollution has become widespread in the oceans, accumulating to high levels in predator fish and once in the food chain poses documented risks to infants, children and adults.
Coal is the major source of mercury pollution, its toxins vaporizing into the air as it burns and eventually washing into the oceans.
Pollution along the coasts by industrial waste, agricultural runoff, pesticides, and human sewage has increased the frequency of Harmful Algal Blooms (HABs) producing toxins associated with dementia, amnesia, neurological damage, and rapid death.
Plastic waste – entering the oceans at a rate of more than 10 million tons each year – kills seabirds and fish and is consumed by humans in the form of toxic microscopic particles, now found in all humans. The waters most seriously impacted by ocean pollution are the Mediterranean Sea, the Baltic Sea, and Asian rivers.

Plastic pollution is suffocating our ocean and the many animals that call it home. Researchers estimate there are now over 5.25 trillion pieces of plastic in the ocean with 8.75 million metric tons being added every year. This pollution is impacting our marine ecosystems and wildlife including seabirds, dolphins, fish, turtles, and whales. Plastic fragments are even displacing plankton as the base of the food chain. So what’s the best way to combat this global epidemic facing our ocean? It’s simple: we need to stop the problem at the source! The Surfrider Foundation’s Ocean Friendly Restaurants program does just that. One restaurant, one customer at a time, it increases awareness, drives behavior change, and ultimately creates scalable impact to reduce our plastic footprint.
Researchers estimate there are now over 5.25 trillion pieces of plastic in the ocean with the number continuing to grow every day.
An estimated 100 billion plastic bags are used ANNUALLY in the United States.
49.4 billion plastic water bottles were sold in one year’s time with only 31.1% recycled, leaving roughly 34 billion plastic bottles that were littered or went into a landfill in 2015.
Restaurants use an average of 5,800 gallons of water per day
Plastic does not biodegrade so virtually every piece of plastic ever created still exists in some form today!
The Ocean Friendly Restaurants program offers restaurants an easy way to show their commitment to making sustainable choices for our ocean.

UN Moves to Ban Plastics from Oceans
Plastic in the ocean breaks down into such small segments that pieces of plastic from a one liter bottle could end up on every mile of beach throughout the world.
Billions of pounds of plastic can be found in swirling convergences in the oceans making up about 40 percent of the world's ocean surfaces. 80 percent of pollution enters the ocean from the land.
46 percent of plastics float (EPA 2006) and it can drift for years before eventually concentrating in the ocean gyres.
The Great Pacific Garbage Patch is located in the North Pacific Gyre off the coast of California and is the largest ocean garbage site in the world. This floating mass of plastic is twice the size of Texas, with plastic pieces outnumbering sea life six to one.
Plastic constitutes approximately 90 percent of all trash floating on the ocean's surface, with 46,000 pieces of plastic per square mile.
One million sea birds and 100,000 marine mammals are killed annually from plastic in our oceans. 44 percent of all seabird species, 22 percent of cetaceans, all sea turtle species and a growing list of fish species have been documented with plastic in or around their bodies.

- Cyanobacteria are arguably the most successful group of microorganisms on earth. They are the most genetically diverse; they occupy a broad range of habitats across all latitudes, widespread in freshwater, marine, and terrestrial ecosystems, and they are found in the most extreme niches such as hot springs, salt works, and hypersaline bays. Photoautotrophic, oxygen-producing cyanobacteria created the conditions in the planet's early atmosphere that directed the evolution of aerobic metabolism and eukaryotic photosynthesis.
Cyanobacteria fulfill vital ecological functions in the world's oceans, being important contributors to global carbon and nitrogen budgets.

Endangered Tiny-Miniscule Species
GP360: The standard approach, when looking at threatened species, is to focus on well-known larger species. The Red List is widely known for its work to identify species at risk of extinction. Its work forms the basis for many biodiversity preservation efforts. The focus on [https://en.wikipedia.org/wiki/The_world's_100_most_threatened_species larger, readily identified animals is the norm and these species, often mammals, provides just a part of the larger picture of our threatened environment.
Large 'charismatic', or 'iconic' species, most often eclipse recognition of rarely considered species that are not even 'known' or known to be in danger...
The reality is that much of the extinction in our era is of the small species, the lesser known, unknown and unconsidered species, whether in the rich biospheres of the rainforest or the oceans, the micro-organisms are at risk and in peril of collapse.
When we speak of Plankton, as a profoundly critical keystone species, the food chain of the oceans begins with plankton, yet the disruption of the atmosphere and the heating of the ocean, or acidification, will have great consequences to the Phytoplankon, flagellates who cannot move with their limited locomotion system... Acidification of the oceans and the increases of heat or strengthened suns rays due to changes in atmospheric conditions and UV radiation can have deadly consequences to the 'least of and smallest of' the species -- and as a result effect the larger systems in ways that science is only now beginning to measure and monitor.
We are, our species is, beginning to understand that as the small animals comprising the foundations of the 'food chain' and biosphere systems are disrupted, endangered and/or destroyed, the rest of the food chain and integral ecological connections between species will be disrupted, endangered, and/or destroyed.
The understanding of and protection of biodiversity, large and small, easily recognized and difficult to recognize, is a great challenge of the era in which we live... loss of biodiversity is producing a 'ripple effect' over time, a threat multiplier that demands strategic environmental security as a key goal, a green policy objective beginning with awareness and policies and practices of sustainability.

Marine Biodiversity Strongly Linked to Ocean Temperature
ScienceDaily / 2010 — In an unprecedented effort published online by the international journal Nature, a team of scientists mapped and analyzed global biodiversity patterns for over 11,000 marine species ranging from tiny plankton to sharks and whales.
The researchers found striking similarities among the distribution patterns, with temperature strongly linked to biodiversity for all thirteen groups studied. These results imply that future changes in ocean temperature, such as those due to climate change, may greatly affect the distribution of life in the sea.

CO2 Carbon Pollution and Ocean Ecosystems
Big Trouble Ahead for Ocean Plankton
Sobering news: Ocean acidification will likely kill off some phytoplankton species and let others thrive, while warming waters will likely cause mass phytoplankton migrations toward the poles. In short: The base of the marine food web could be in for some serious upheaval in the coming decades. Here’s more from MIT News:
“I’ve always been a total believer in climate change, and I try not to be an alarmist, because it’s not good for anyone,” says (Dr. Stephanie) Dutkiewicz, who is the paper’s lead author. “But I was actually quite shocked by the results. The fact that there are so many different possible changes, that different phytoplankton respond differently, means there might be some quite traumatic changes in the communities over the course of the 21st century. A whole rearrangement of the communities means something to both the food web further up, but also for things like cycling of carbon.”
Dutkiewicz and her colleagues studied 154 published experiments...
GLOBAL PLANKTON WATCH
THE GLOBAL SEAFARER STUDY OF THE MARINE PHYTOPLANKTON
ABOUT THE PROJECT
The phytoplankton in the sea account for approximately 50% of all photosynthesis on Earth and, through the food web they support, they underpin the marine food chain.
Living at the surface of the sea the phytoplankton are particularly sensitive to changes in sea surface temperature.
We need to know much more about these changes and you can help by making a simple piece of scientific equipment called a Secchi Disk and using the free Secchi App.
Full instructions for the project are included in the free Secchi App.
Press Release -- Scientists fear the population of the microscopic beings is in decline due to rising sea temperatures and, if true, that could have consequences for every aspect of marine life.
Plankton biologist Dr Richard Kirby, who is leading the study, said: "As the phytoplankton live at the surface of the sea they are being affected by rising sea temperatures due to climate change. A scientific paper published in 2010 suggested the ocean's plankton population had declined by as much as 40 per cent since 1950. Like all marine creatures, phytoplankton have a preferred optimum sea temperature no matter where they are in the world and we need to know more about how they are changing in order to understand the effects on the ocean's biology.” To check the levels of phytoplankton in our oceans, marine experts have developed a free smart phone app for sailors and fishermen to use wherever they are in the world.
Dr Kirby added: "The Secchi Disks are still used by marine scientists to study phytoplankton but there are too few scientists to survey the world's oceans as well as we would wish. This app enables seafarers around the world to take part in a science project and if we can just get a small percentage of the global population of sailors involved, we can generate a database that will help us understand how life in the oceans is changing. It would help us learn much more about these important organisms at a crucial time when their habitat is altering due to climate change."
The Secchi app has been developed by Dr Nicholas Outram and Dr Nigel Barlow, from Plymouth University’s School of Computing and Mathematics, and the database will be maintained by Pixalytics Ltd.

Marine food chains at risk of collapse, extensive study of world's oceans finds
Important ecosystems could be massively damaged by 2050 unless greenhouse gas emissions and localised pollution is drastically reduced, researchers say...
The food chains of the world’s oceans are at risk of collapse due to the release of greenhouse gases, overfishing and localised pollution, a stark new analysis shows.
A study of 632 published experiments of the world’s oceans, from tropical to arctic waters, spanning coral reefs and the open seas, found that climate change is whittling away the diversity and abundance of marine species.
The paper, published in the Proceedings of the National Academy of Sciences, found there was “limited scope” for animals to deal with warming waters and acidification, with very few species escaping the negative impact of increasing carbon dioxide dissolution in the oceans.

Phytoplankton Oxygen Factories
Phytoplankton are the grass of the sea. They are floating, drifting, plant-like organisms that harness the energy of the Sun, mix it with carbon dioxide that they take from the atmosphere, and turn it into carbohydrates and oxygen.
Phytoplankton are critical to the marine food web, being the primary producers of food for the oceanic food web, from zooplankton to fish and shellfish to whales.
Like plants and trees on land, phytoplankton give us a lot more than food. It is estimated that 50 to 80 percent of the oxygen in our atmosphere has been produced by phytoplankton. At the same time, they are responsible for drawing down significant portions of the carbon dioxide from the air. The tiniest of living organisms exert an outsized influence on the planet.

Global trends show seabird populations dropped 70 per cent since 1950s
“Seabirds are particularly good indicators of the health of marine ecosystems,” said Paleczny. ”When we see this magnitude of seabird decline, we can see there is something wrong with marine ecosystems. It gives us an idea of the overall impact we’re having.”
The dramatic decline is caused by a variety of factors including overfishing of the fish seabirds rely on for food, birds getting tangled in fishing gear, plastic and oil pollution, introduction of non-native predators to seabird colonies, destruction and changes to seabird habitat, and environmental and ecological changes caused by climate change.
Seabirds tend to travel the world’s oceans foraging for food over their long lifetimes, and return to the same colonies to breed. Colony population numbers provide information to scientists about the health of the oceans the birds call home.

Contrasting futures for ocean and society from different anthropogenic CO2 emissions scenarios
Via Science / July 2015
Although the ocean moderates anthropogenic climate change, this has great impacts on its fundamental physics and chemistry, with important consequences for ecosystems and people. Despite the ocean’s critical role in regulating climate—and providing food security and livelihoods for millions of people—international climate negotiations have only minimally considered impacts on the ocean. Here, we evaluate changes to the ocean and its ecosystems, as well as to the goods and services they provide, under two contrasting CO2 scenarios: the current high-emissions trajectory (Representative Concentration Pathway 8.5, RCP8.5) and a stringent emissions scenario (RCP2.6) consistent with the Copenhagen Accord of keeping mean global temperature increase below 2°C in the 21st century. To do this, we draw on the consensus science in the latest assessment report of the Intergovernmental Panel on Climate Change and papers published since the assessment.
Warming and acidification of surface ocean waters will increase proportionately with cumulative CO2 emissions (see figure). Warm-water corals have already been affected, as have mid-latitude seagrass, high-latitude pteropods and krill, mid-latitude bivalves, and fin fishes. Even under the stringent emissions scenario (RCP2.6), warm-water corals and mid-latitude bivalves will be at high risk by 2100. Under our current rate of emissions, most marine organisms evaluated will have very high risk of impacts by 2100 and many by 2050. These results—derived from experiments, field observations, and modeling—are consistent with evidence from high-CO2 periods in the paleorecord.
Impacts to the ocean’s ecosystem services follow a parallel trajectory. Services such as coastal protection and capture fisheries are already affected by ocean warming and acidification. The risks of impacts to these services increase with continued emissions: They are predicted to remain moderate for the next 85 years for most services under stringent emission reductions, but the business-as-usual scenario (RCP8.5) would put all ecosystem services we considered at high or very high risk over the same time frame. These impacts will be cumulative or synergistic with other human impacts, such as overexploitation of living resources, habitat destruction, and pollution. Fin fisheries at low latitudes, which are a key source of protein and income for millions of people, will be at high risk.
Four key messages emerge. First, the ocean strongly influences the climate system and provides important services to humans. Second, impacts on key marine and coastal organisms, ecosystems, and services are already detectable, and several will face high risk of impacts well before 2100, even under the low-emissions scenario (RCP2.6). These impacts will occur across all latitudes, making this a global concern beyond the north/south divide. Third, immediate and substantial reduction of CO2 emissions is required to prevent the massive and mostly irreversible impacts on ocean ecosystems and their services that are projected with emissions greater than those in RCP2.6. Limiting emissions to this level is necessary to meet stated objectives of the United Nations Framework Convention on Climate Change; a substantially different ocean would result from any less-stringent emissions scenario. Fourth, as atmospheric CO2 increases, protection, adaptation, and repair options for the ocean become fewer and less effective.
Ocean acidification and warming provide immediate and compelling arguments for rapid reductions in CO2 emissions and atmospheric CO2 drawdown

NASA Study Finds Indian, Pacific Oceans Temporarily Hide Global Warming
-- The new study used ocean temperature measurements from a global array of 3,500 Argo floats and other ocean sensors.
-- Temperature data from the global ocean (2003-2012) at four depths
-- Via NASA Earth Observatory http://www.nasa.gov/earth
A new NASA study of ocean temperature measurements shows in recent years extra heat from greenhouse gases has been trapped in the waters of the Pacific and Indian oceans. Researchers say this shifting pattern of ocean heat accounts for the slowdown in the global surface temperature trend observed during the past decade.
Researchers from NASA’s Jet Propulsion Laboratory (JPL), Pasadena, California, found a specific layer of the Indian and Pacific oceans between 300 and 1,000 feet (100 and 300 meters) below the surface has been accumulating more heat than previously recognized. They also found the movement of warm water has affected surface temperatures. The result was published Thursday in the journal Science...
In the study, researchers analyzed direct ocean temperature measurements, including observations from a global network of about 3,500 ocean temperature probes known as the Argo array. These measurements show temperatures below the surface have been increasing.
The Pacific Ocean is the primary source of the subsurface warm water found in the study, though some of that water now has been pushed to the Indian Ocean. Since 2003, unusually strong trade winds and other climatic features have been piling up warm water in the upper 1,000 feet of the western Pacific, pinning it against Asia and Australia.
"The western Pacific got so warm that some of the warm water is leaking into the Indian Ocean through the Indonesian archipelago," said the lead author of the study.
The movement of the warm Pacific water westward pulled heat away from the surface waters of the central and eastern Pacific, which resulted in unusually cool surface temperatures during the last decade. Because the air temperature over the ocean is closely related to the ocean temperature, this provides a plausible explanation for the global cooling trend in surface temperature.
Cooler surface temperatures also are related to a long-lived climatic pattern called the Pacific Decadal Oscillation, which moves in a 20 to 30 year cycle. It has been in a cool phase during the entire time surface temperatures showed cooling, bringing cooler-than-normal water to the eastern Pacific and warmer water to the western side. There currently are signs the pattern may be changing to the opposite phase, with observations showing warmer-than-usual water in the eastern Pacific.
"Ocean heating in the Pacific will definitely drive a major surge in global surface warming"
Previous attempts to explain the global surface temperature cooling trend have relied more heavily on climate model results or a combination of modeling and observations, which may be better at simulating long-term impacts over many decades and centuries. This study relied on observations, which are better for showing shorter-term changes over 10 to 20 years. In shorter time spans, natural variations such as the recent slowdown in global surface temperature trends can have larger regional impacts on climate than human-caused warming.

How many ocean species are there?
Not only do we not know, but the answer may be unknowable for the foreseeable future, given the size of the challenge, especially at the microbial level. Even with the ambitious effort of the Census of Marine Life and the combined institutional efforts of various navies, oceanographic research institutions, and individuals, currently less than 5 percent of the ocean has been seen, let along explored; for the deep sea, below 305 meters (1,000 feet), the figure drops to about one percent.
The magnitude of what remains to be discovered is exemplified by the discoveries of Richard Pyle, a truly intrepid biologist who uses cutting-edge re-breather diving systems and special mixes of gases to explore the almost-light/almost-dark region of the sea known as the twilight zone, from 100 to 200 meters (330 to 660 feet) down. He finds new species of fish at the rate of 12 to 13 (and sometimes as many as 30) per hour. For invertebrates, the number is at least ten times that.
Given the number of new forms of life discovered in regions examined for the first time, it is now estimated that the ocean holds at least ten million species. Some believe the number may be closer to a hundred million--not counting the microbes that eclipse all other forms of life in terms of numbers and sheer mass.

Observing the world's fishing fleet, real time and over time
Game-changer Technology
Automatic identification systems, AIS signals, carry information about fishing vessels, e.g., name, country of origin, speed and position.
Today, except for illegals and pirates, the sector has reached a point where there is a comprehensive picture of where vessels are and where they’ve been, at any given time, encapsulated in billions of individual AIS signals.
At the same time, advances in machine learning and artificial intelligence are making it possible to see patterns in this glut of data.
A collaboration between environmental watchdog SkyTruth, Global Fishing Watch and Google, has been instrumental in laying the groundwork for AIS data analysis. The group has created algorithms that can be applied to large amounts of data to show the type of fishing activity, location or travel path of vessels, and made some of this data accessible in the form of an interactive map...
This complex supply chain can be documented and recorded electronically at sea and in port.
This type of measuring and monitoring work can bring reform to the fishing industry and help curb over fishing, resource depletion, and fraud, which is prevalent with seafood everywhere in the world.
High seas ocean fishery resources do not belong to a single nation, but rather are viewed as an international commons, a vital resource that is to be shared.
Knowing more about global fishing patterns can help inform policymakers and consumers... research is just getting started in this field.
“AIS tracking is going to increase and become more elaborate.”

From the Project Announcement:
Global Fishing Watch is the product of a technology partnership between SkyTruth, Oceana, and Google Earth Outreach that is designed to show all of the trackable fishing activity in the ocean.
This interactive web tool – currently in prototype stage – is being built to enable anyone to visualize the global fishing fleet in space and time. Global Fishing Watch will reveal the intensity of fishing effort around the world, one of the stressors contributing to the precipitous decline of our fisheries.
With hundreds of millions of people around the world depending on our ocean for their livelihoods, and many more relying on the ocean for food, ensuring the long-term sustainability of our ocean is a critical global priority. We need a tool that harnesses the power of citizen engagement to hold our leaders accountable for maintaining an abundant ocean.
Global Fishing Watch will be available to the public, enabling anyone with an internet connection to monitor when and where commercial fishing is happening around the globe.
Citizens can use the tool to see for themselves whether their fisheries are being effectively managed. Seafood suppliers can keep tabs on the boats they buy fish from. Media and the public can act as watchdogs to improve the sustainable management of global fisheries. Fisherman can show that they are obeying the law and doing their part. Researchers will have access to a multi-year record of all trackable fishing activity.
The tool uses a global feed of vessel locations extracted from Automatic Identification System (AIS) tracking data collected by satellite, revealing the movement of vessels over time. The system automatically classifies the observed patterns of movement as either “fishing” or “non-fishing” activity.
This version of the Global Fishing Watch started with 3.7 billion data points, more than a terabyte of data from two years of satellite collection, covering the movements of 111,374 vessels during 2012 and 2013. We ran a behavioral classification model that we developed across this data set to identify when and where fishing behavior occurred. The prototype visualization contains 300 million AIS data points covering over 25,000 unique vessels. For the initial fishing activity map, the data is limited to 35 million detections from 3,125 vessels that we were able to independently verify were fishing vessels. Global Fishing Watch then displays fishing effort in terms of the number of hours each vessel spent engaged in fishing behavior, and puts it all on a map that anyone with a web browser will be able to explore.
