The case for a global ocean carbon observation network

Since 1958, the Global Carbon Budget has tracked anthropogenic CO2 emissions and their redistribution among the atmosphere, ocean, and land. Annual budgeting is necessary due to large year-to-year variability in CO2 sources (primarily fossil fuels) and sinks (primarily climate driven). However, uncertainties remain, due to a lack of data, that hinder both research seeking to better understand the global carbon cycle and efforts to independently verify reported CO2 emissions. To refine our understanding of how much atmospheric carbon the planet—and the life it supports—can tolerate, we must significantly increase observational data collection, especially in remote, chronically undersampled regions.

Saildrone proposes a global fleet of unmanned surface vehicles (USVs) for sustained carbon monitoring, supported by a public-private partnership made up of the international science community and private companies developing innovative solutions for ocean observation.

Seeking impact partners

Saildrone proposes a global fleet of 40 vehicles to collect carbon data for sustained monitoring. Saildrone’s USVs are environmentally friendly, using wind power for propulsion and solar power to run the onboard sensors, computers, and satellite and navigation instruments. In addition to carbon data, each Saildrone autonomous vehicle collects nearly two dozen meteorological and oceanographic metrics above and below the sea surface at a frequency of 1 minute or greater.

Princeton project expands to create a worldwide fleet of robotic floats to monitor ocean health

On October 29, the National Science Foundation (NSF) announced a $53 million grant — shared among a consortium of the country’s top ocean research institutions — to build a global network of chemical and biological sensors that will monitor ocean health.

Scientists at Princeton University, Monterey Bay Aquarium Research Institute (MBARI), University of Washington, Scripps Institution of Oceanography at UC San Diego and Woods Hole Oceanographic Institution will use this grant to build and deploy 500 robotic ocean monitoring floats around the globe. The new program builds on the successful Southern Ocean Carbon and Climate Observations and Modeling (SOCCOM) project based at Princeton that has deployed similar floats in the ocean around Antarctica, proving their usefulness as year-round reporters of ocean chemistry and biological activity.

La Parguera (video; in Spanish)

Since 2008 the NOAA’s Ocean Acidification program (OAP) buoy has been installed in La Parguera, Puerto Rico where oceanographic studies of chemistry, biology, geology, and physics of the Caribbean Sea have been conducted for more than 50 years. Below is a video on La Parguera and Ocean Acidification.

Cir#20/84: Pacific Islands survey to assess Pacific members capacity to monitor and study ocean acidification

SPREP is working with the Ocean Foundation and NOAA to develop a new three-year project focused on building capacity to monitor and study ocean acidification in the Pacific Islands.

Building CapacIty in Ocean AcidificaTion MoniToring in the Gulf of GuineA (BIOTTA)

The Gulf of Guinea (GoG) is host to many distinct ecosystems, among which is the Guinea Current Large Marine Ecosystem extending from the intense upwelling area of the Guinea Current in the north to the Benguela Current in the south. The GoG region is however, characterized by a high poverty rate within fishing communities, with an average daily income of USD 6.1 for over 610,000 artisanal fishers (IDAF, 1997), with the situation getting worse in recent times due to continual decline in fish landings. Dotted along the relatively wide continental shelf of the GoG are several lagoonal/estuarine systems including adjacent coastal marine waters that provide livelihood benefits i.e., nutrition and jobs to deprived communities living around them. The productive waters of the GoG support shellfish (oysters, mussels, clams, crabs etc.) and a diverse finfish fishery which provide significant livelihood income to coastal communities in countries such as Cote d’Ivoire, Ghana, Togo, Benin, Nigeria etc. Climate change in West Africa is characterized by increasing temperatures, changing ocean pH, erratic rainfall patterns and an increase in the number of extreme events. Changing ocean pH coupled with other climate and non-climate stressors such as pollution and overfishing present huge threats to the future of the fishery and other marine resources in the region. A lack of skills in the measurement of ocean acidification (OA) hinders ocean observation which puts the fishery and other marine biological resources in the GoG at a greater risk. This deficit in ocean acidification measurement skills forestalls our understanding of species vulnerability to changing pH. The BIOTTA working group will equip graduate students, early career ocean scientists and other marine science professionals in the GoG region with skills on sustainable OA data acquisition to expand our understanding of the threats, risks and impacts to marine ecosystems and chart pathways for sustainable management of marine resources at risk to OA in the GoG region.

SOCAT Version 2020 released

SOCAT version 2020 was released on the 16th of June 2020, containing data submitted on or before 15th of January 2020. Data submissions for the next version are welcome at any time, and will be included in the next SOCAT release in 2021.

SOCAT version 2020 contains 28.2 million in situ surface ocean fCO2 (fugacity of CO2) measurements for the global ocean and coastal seas with an accuracy < 5 μatm, while a further 2.3 million fCO2 values with an accuracy of 5 to 10 μatm are made available separately. The Surface Ocean CO2 Atlas ( documents the increase in surface ocean CO2 (carbon dioxide), a critical measure as the oceans are taking up one quarter of the global CO2 emissions from human activity. The SOCAT community-led synthesis product is a key step in the value chain based on in situ inorganic carbon measurements of the oceans, which provides policy makers with essential information on ocean CO2 uptake in climate negotiations. The global need for accurate knowledge of ocean CO2 uptake and its variation makes sustained funding for in situ surface ocean CO2 observations imperative. The annual SOCAT release is a Voluntary Commitment for SDG 14.3 (#OceanAction20464) and contributes to the UN Decade of Ocean Science for Sustainable Development.

Survey on ocean acidification impacts on coral reefs (in French)

Les récifs coralliens sont réputés pour leurs magnifiques paysages sous-marins colorés, mais ce sont des écosystèmes lointains pour une grande partie d’entre nous. Nous avons besoin de protéger ces écosystèmes exceptionnels et pour cela nous souhaitons faire un bilan sur l’état des connaissances sur les récifs coralliens. Aidez-nous en remplissant ce questionnaire.

Ce court sondage ne vous prendra pas plus de 10 minutes. Bien évidemment, vos réponses resteront totalement anonymes. Nous vous remercions par avance pour votre précieuse contribution !

Call for manuscripts: Microbial response to a rapidly changing marine environment: global warming and ocean acidification

Submission Deadlines
30 June 2020: Abstract
31 October 2020: Manuscript

About this Research Topic
Under the global climate change, the world’s oceans are warming more quickly than previously thought. The ocean warming could lead to remarkable changes in marine environments, such as ocean deoxygenation, acidification, and sea ice melting. Marine ecosystems are undergoing significant changes due to the current environmental changes caused by a rapidly warming ocean.

Microbial communities are diverse and productive assemblages, including phytoplankton, protists, and the two main groups of prokaryotes (Bacteria and Archaea). Since they drive major biogeochemical cycles and support higher food-webs globally, microbes are a vital component of the marine ecosystem. Moreover, microbes can be an important indicator for the environmental changes, because physiological and ecological alterations in microbial communities can herald changes not only in pathways of energy transfer through food-web but also in biogeochemical cycles. Considering the microbial communities’ pivotal roles in ongoing climate change, it is important to understand which current changes in microbial communities have occurred to date and which future changes might arise under ongoing environmental forcing of the warming ocean.
