Missions
In regional ocean/ice/biogeochemistry models (OBMs) applied to Arctic coastal seas, the properties of
terrigenous sediments are rarely integrated into physical and biogeochemical processes. To address this gap, the missions will consist of (i) effectively integrating sediments into these OBMs, (ii) comparing them with ocean color measurements and products, and (iii) analyzing the effect on CO2 fluxes at the air/water interface.
Activities
– Deployment, compilation, and execution of the ECCO-Darwin model on the supercomputer
– Numerical developments on the ECCO-Darwin model code
– Analysis of numerical model outputs
– Processing and analysis of in situ measurement data and spatial remote sensing data
– Participation in the scientific supervision of students
– Participation in national and international mobility programs
Skills
– Training in oceanography
– Proficiency in parallel numerical computation
– Proficiency in hydro-sedimentary modeling in coastal Arctic environments, including
interactions with waves
– Proficiency in coupled ocean/sea ice numerical modeling in coastal Arctic environments
– Proficiency in Python and Fortran programming languages
Work Context
The project is part of the international Refuge-Arctic project (https://www.refuge-arctic.ulaval.ca) with
links to the NASA FORTE project, whose overall objective is to better understand and predict the role
played by the land/sea interface in the physical and biogeochemical response of the coastal Arctic Ocean.
The postdoctoral project will be conducted at UMR7266 LIENSs CNRS-La Rochelle University. Scientific
supervision will be provided by Professor Vincent Le Fouest (LIENSs).
The working environment is highly interdisciplinary and international.
Work in a restricted access
zone (ZRR), i.e., with regulated access in order to protect national scientific and technical potential.
The position is located in a sector under the protection of scientific and technical potential (PPST), and therefore requires, in accordance with the regulations, that your arrival is authorized by the competent authority of the MESR.
Constraints and risks
Academic stays abroad (max. 1 month) are possible and should be expected.
