Titre: A vision for understanding the ocean with a global biogeochemical sensor network
Observing biogeochemical processes at a global scale in a changing ocean is one of the most pressing issues in the ocean sciences. Changing oxygen levels, increasing acidity and greater thermal stratification all have the potential to substantially alter fluxes of carbon, oxygen and nitrogen. Yet there is no extant observing system capable of resolving these processes in situ at the global scale. Deployment of a global ocean observing system based on biogeochemical sensors on profiling floats and gliders is rapidly becoming feasible. In this talk, I will focus on the potential for the development of such a system, which we call GLOBE (GLobal Ocean Biogeochemical Experiment). GLOBE would be modeled on the Argo system and would function as a biogeochemical Argo program (Bio-Argo) with open data access.
