Marine Biogeochemistry
Merging bio optical data from Biogeochemical Argo floats and models in marine biogeochemistry
... Abstract. New autonomous robotic platforms for observ- ing the ocean, i.e. Biogeochemical-Argo (BGC-Argo) floats, have drastically increased the number of vertical profiles of irradiance, photosynthetically available ...
