The structure you will be joining

UMR235 Institut Méditerranéen d'Océanologie OSU PYTHEAS. Team: Marine Environment . The M.I.O is an oceanology research laboratory of the Universities of Aix-Marseille, Toulon, CNRS and IRD. It is part of OSU Pytheas and a partner of Labex OT-Med. Its objectives are to better understand the oceanic system and its evolution in response to global change. It is a center of expertise in marine biology, ecology, biodiversity, microbiology, fisheries, physics, chemistry, biogeochemistry and sedimentology.

The ANR BOOST is headed by Fanny Houlbrèque, a researcher at UMR 250 ENTROPIE umr-entropie.ird.nc. The Entropie unit is a UMR with 5 supervisory bodies (Université de La Réunion, IRD, CNRS, Ifremer and Université de Nouvelle-Calédonie) whose aim is to better understand the functioning of marine and island ecosystems in the tropical Indo-Pacific in the context of global warming.

An attractive mission

The main objective of the post-doc is to use ocean color remote sensing to identify lagoon zones favorable to mesotrophic corals that are more resistant to future heat waves (MHWs). Our aim is to map the areas of high phytoplankton biomass in Case 1 outside the lagoon, and Case 2 inside the lagoon, using satellite data from different ocean color sensors and resolutions, validated by in situ data.

Your activities will include:

• Operation of the Copernicus-GlobColour series of level 4 "cloud-free" daily products with 4 km resolution (chlorophyll-a, primary production)
• Analysis of SGLI and Sentinel 3 (S3) composites at 300 m resolution
• Use of a Sentinel-2 (S2) mosaic with 20 m resolution
• Use of machine learning to predict the distribution of chl-a in the lagoon of New Caledonia
• Use of comparisons between multispectral imagery (Sentinel 2) and chl-a obtained from all IRD oceanographic campaigns inside and outside the New Caledonian lagoon.

Your future team

The post-doc will be assigned to the M.I.O. His tutors will be Martine Rodier (M.I.O.) in Marseille (marine biology) with the expertise of Cécile Dupouy in ocean color remote sensing, and Corina Iovan (ENTROPIE). A Master 2 student will also be recruited.
