The Ocean Carbon and Biogeochemistry Scientific Steering Committee (OCB SSC) was formed in February 2006. The OCB SSC was created jointly by NSF, NASA and NOAA to provide critical leadership to the OCB community by helping to identify research priorities and promote, plan, and coordinate collaborative, multidisciplinary research opportunities in ocean biogeochemistry. SSC members serve a term of three years. Parentheses indicate term end (end of calendar year) for each member.
