The GO-BGC program deploys biogeochemical floats in the world’s ocean.
The is a project funded by the US National Science Foundation to build a global network of chemical and biological sensors that monitor ocean health. This new network of floats collects data on the chemistry and the biology of the ocean from the surface to a depth of 2,000 meters, augmenting the existing that monitors ocean temperature and salinity. Data streaming from the float array is freely available within a day of being collected via the Argo data system, and is used by researchers around the world. These data allow scientists to pursue fundamental questions concerning ocean ecosystems, observe ocean health and productivity, and monitor the elemental cycles of carbon, oxygen, and nitrogen in the ocean through all seasons of the year. Such essential data are needed to improve computer models of ocean fisheries and climate, and to monitor and forecast the effects of ocean warming and ocean acidification on sea life. Additional BGC floats are deployed in the Southern Ocean as part of the (SOCCOM) project.
