Welcome to OCB
OCB was established in 2006 as one of the major activities of the U.S. Carbon Cycle Science Program, an interagency body that coordinates and facilitates activities relevant to carbon cycle science, climate, and global change issues. The scientific mission of OCB is to study the evolving role of the ocean in the global carbon cycle, in the face of environmental variability and change through studies of marine biogeochemical cycles and associated ecosystems.
Improve understanding and prediction of:
- oceanic uptake and release of atmospheric CO2 and other greenhouse gases;
- environmental sensitivities of biogeochemical cycles, marine ecosystems, and interactions between the two
Currently Identified Research Priorities
- Climate- and human-driven changes in ocean chemistry (e.g., acidification, expanding low-oxygen conditions, nutrient loading, etc.) and associated impacts on biogeochemical cycles and marine ecosystems
- Ocean carbon uptake and storage
- Estuarine and coastal carbon fluxes and processes, including exchanges with open ocean, terrestrial, and atmospheric reservoirs
- Water column and seafloor biological and biogeochemical processes and associated effects on carbon export and the biological pump
- Molecular-level responses of marine organisms to their changing environment
- Impacts of evolutionary changes on community structure, function and biogeochemical cycling in the face of global change

Evidence of Millennial-Scale Changes in Plankton Community Composition in North Pacific Subtropical Gyre
Two recent studies published by Sherwood et al. (2014) in Nature
and McMahon et al. (2015) in Science
present evidence of millennial-scale changes in plankton community composition and biogeochemical cycling in the world’s largest contiguous ecosystem, the North Pacific Subtropical Gyre. Molecular-level isotopic records preserved in deep-sea proteinaceous corals show increasing dominance of diazotrophic prokaryotes in the plankton community resulting in a greater proportion of export production originating from nitrogen fixation. By circumventing nitrate limitation in more stratified ocean waters, this new regime may provide a negative feedback to rising atmospheric carbon dioxide concentrations.
