Moving toward finer scales in oceanography: Predictive linear functional model of Chlorophyll a profile from light data
International audience The Southern Ocean plays a key role in ocean–atmosphere carbon dioxide fluxes. Estimation of carbonexchanges between ocean and atmosphere must rely on accurate estimations of primary productivitywhich require measurements of phytoplankton concentration within the water column....
