  • The Southern Ocean Carbon and Climate Observations and Modeling (SOCCOM) program will commence in September 2014
  • The Southern Ocean Carbon and Climate Observations and Modeling (SOCCOM) program will commence in September 2014

     

     

    The Southern Ocean Carbon and Climate Observations and Modeling (SOCCOM website) program will commence in September 2014 with an initial commitment of $3.5 million per year over 6 years ($21 million dollars total). SOCCOM program is a six‐year initiative funded by the US NSF to drive a transformative shift in the scientific and public understanding of the role of the Southern Ocean in climate change and biogeochemistry.

     

    The goals of the program are to:

     

     

    ● Extend sparse Southern Ocean biogeochemical observations by deploying a robotic observing system composed of ~200 autonomous floats that will provide nearly continuous coverage in time and horizontal space over the entire Southern Ocean, as well as vertical coverage deep into the water column.

     

    ● Using this observational data, analyze and improve a new generation of high resolution (1/10°) earth system models to both increase our understanding of the Southern Ocean’s current workings and make better projections of the future trajectory of the Earth’s climate and biogeochemistry.

     

    ● Educate a new generation of ocean scientists trained in both ocean observation and simulation, and develop a sophisticated outreach effort to disseminate results to the broadest possible community.

     

     

    Professor Jorge Sarmiento of Princeton University, USA will serve as Director of the project, which will consist of three teams:

     

    ● An observational team headed by Professor Lynne Talley of Scripps Institution of Oceanography (U.C. San Diego) in collaboration with Dr. Ken Johnson of the Monterey Bay Aquarium Research Institute and Professor Stephen Riser of the University of Washington;

     

    ● A modeling team headed by Professor Joellen Russell at the University of Arizona in collaboration with Sarmiento and colleagues at Princeton as well as NOAA’s Geophysical Fluid Dynamics Laboratory; and

     

    ● A broader impacts team headed by Dr. Heidi Cullen, Chief Climatologist at Climate Central, a non‐profit science journalism organization headquartered in Princeton, NJ.

    Why study the Southern Ocean?

     

    Because of the harsh conditions in the Southern Ocean, traditional measurements of ocean properties made from ships are few and far between. Modeling studies, however, suggest that this region plays important roles in the planet’s carbon and climate cycles.

     

    First, studies show that although the Southern Ocean comprises only about 30% of the world’s ocean area, it accounts for half the ocean’s uptake of anthropogenic carbon from the atmosphere and the majority of its uptake of heat. Second, models indicate that upwelling in the Southern Ocean delivers nutrients to lower latitude surface waters that are critical to ocean ecosystems around the world. Third, the impacts of ocean acidification from rising CO2 are projected to be most severe in the Southern Ocean, with ecosystem tipping points being reached in a few decades.

     

    The cutting‐edge observations and modeling carried out under the SOCCOM project will help researchers better understand the inner workings of the Southern Ocean and how it impacts Earth’s climate and biosphere. SOCCOM’s modeling studies will also help us assess the impact of changes in the Southern Ocean on the global climate.

     

     

    What makes this program unique?

     

    The international Argo program has deployed thousands of autonomous floats to measure temperature and salinity in the world’s oceans. The SOCCOM project is augmenting conventional Argo floats with biogeochemical sensors to measure carbon (pH), nutrients (nitrate), and oxygen.

     

    SOCCOM is the world’s first large‐scale biogeochemical Argo deployment. The project will increase the number of biogeochemical measurements made monthly in the Southern Ocean by 10‐30 times (more in the Southern Hemisphere winter, when observations are scarcest), and the data will be made freely available to the public. SOCCOM is also unusual in combining an innovative observational program with a strong modeling program, and in integrating professional outreach partners into the program.

     

     

    The IOCCP promotes the development of a global network of ocean carbon observations for research through technical coordination and communication services, international agreements on standards and methods, and advocacy and links to the global observing systems. The IOCCP is co-sponsored by the Scientific Committee on Oceanic Research and the Intergovernmental Oceanographic Commission of UNESCO. Read more…
