Members of the biogeochemical research community are taking steps to keep their work thriving in the next millennium. Since 1984, major questions in ocean biogeochemical research have been studied in a concerted manner in the Joint Global Ocean Flux Study (JGOFS) program. This effort as well as the World Ocean Circulation Experiment (WOCE) and Global Ocean Ecosystem Dynamics program (GOED) is part of the U.S. Global Change Research Plan (USGCRP). The JGOFS Science Plan established two goals: to determine and understand on a global scale the processes controlling the time-varying fluxes of carbon and associated biogenic elements in the ocean, and to develop the capability to predict on a global scale the response of oceanic biogeochemical processes to anthropogenic perturbations, particularly those related to climate change.
