Missions
The postdoctoral researcher will contribute to an in-depth study of the mechanisms controlling the variability of surface salinity in the Gulf of Mexico, in particular the interaction between the Mississippi plume and the Loop Current. This work is part of the ESA CCI+SSS project. The aim is to combine satellite observations and regional modelling to better understand the export of freshwater to the open ocean and the role of the Loop Current in structuring surface salinity.
Activités
The postdoctoral fellow will be responsible for the following activities:
- Assess the reliability of satellite observations of surface salinity (CCI, AMSR-E, L-band products) in the Gulf of Mexico, comparing them with available in situ observations (PIMEP, WOA, ISAS, TSG, etc.).
Contribute to the generation of a set of high-resolution simulations (10 members) using the NEMO-GOLFO12 ocean model
Analyze the interannual variability of coastal and ocean salinity, combining observational data and numerical simulations.
Quantify the impact of the Loop Current on the structure and transport of the Mississippi plume.
Contribute to the improvement of river forcing in the model by testing different continental input databases.
Promote results through scientific publications and presentations at international conferences.
Compétences
PhD in physical oceanography, climate science or ocean modeling.
Good command of ocean modeling tools (NEMO is an asset).
Experience in processing satellite and in situ data.
Strong skills in scientific programming (Python, Fortran, shell, etc.) and geophysical data analysis.
Ability to work in a team and collaborate in an international context.
Good level of scientific English (written and spoken).
Contexte de travail
The position is based at LEGOS (Laboratoire d'Études en Géophysique et Océanographie Spatiales) in Toulouse, a CNRS / IRD / CNES / Université Toulouse III - Paul Sabatier joint research unit. The laboratory specializes in the study of ocean dynamics at different scales, and develops innovative approaches combining space observations and numerical modeling.
