David Antoine is an oceanographer specialised in satellite Earth observation of the oceans, interested in particular in long-term global changes of phytoplankton. His research interests include marine optics, bio-optics, radiative transfer and applications, satellite ocean colour remote sensing including atmospheric corrections, modelling of oceanic primary production from satellite ocean colour. A current focus is on the Southern and Indian oceans, with a number of active projects in these areas. He has also set up and maintained for ~20 years a long-term time series program in the Mediterranean Sea, collecting physical, optical and biogeochemical data in support to bio-optics research and to calibration / validation of satellite ocean colour remote sensing observations (the BOUSSOLE programme).
