LOPS – Laboratoire d’Océanographie Physique et Spatiale, (UMR6523) – Plouzané
24 Months, contract from CNRS. Starting date: between April and September 2016
The activity will be part of a project entitled “Impact of additional contributions to the vertical mixing for the simulation of Arctic Ocean and sea ice states (ArcticMix) “ funded by the Copernicus Marine Environment Monitoring service (http://www.copernicus.eu/main/marine-monitoring).
The Arctic Ocean has been experiencing some of the most rapid transformations on the planet over the past few decades, with potential impact on the global ocean and climate. State-of-the-art Arctic models are often largely biased, and vertical mixing in these models has been identified as one of the key parameter controlling the simulation of the ocean and sea ice states.
In this project, we propose to evaluate the impact of different sources of vertical mixing on the ocean and sea ice state. These contributions include the effect of the surface waves, the tide and the double diffusive mixing.
To that aim, we will use a high-resolution regional model at 1/12° based on the NEMO/LIM3 modeling platform, in which we will implement the different contributions to vertical mixing.
The project will involve collaborations with scientists and engineers from Mercator-Océan (http://www.mercator-ocean.fr), Environement-Canada and the European Drakkar consortium (http://www.drakkar-ocean.eu)
The engineer is expected to:
- Contribute to the development and validation of the regional configuration at high resolution
- Perform sensitivity experiments to the choice of different parameterizations and numerics
- Contribute to the development and implementation of a parameterization to represent the effect of waves on sea ice and the ocean surface
- Contribute to the model data analysis, and define objective metrics for validation and comparison of the different simulations
- Contribute to the writing of quarterly reports and potentially scientific papers and presentations in international conferences
PhD or Master’s degree in physical oceanography or applied mathematics
SKILLS AND EXPERIENCE:
- Hands-on experience with ocean numerical modeling, experience with the NEMO modeling platform being an advantage
- Good programming skills with Fortran and shell script, experience of parallel programming on supercomputers and knowledge of the NetCDF libraries.
- Good knowledge of scientific softwares (such as Matlab or Python…)
- Scientific knowledge on the Arctic regional oceanography and/or sea ice would be an advantage
- Good oral and written communication in French and English
Applications will be accepted until the position is filled
