The researcher's mission concerns the study of the variability of sea states on multi-decadal scales from an unprecedented wave dataset derived from spatial altimetry (1992-2020). In particular, the contribution of different modes of climate variability on the signal will be investigated in order to characterize the signature of climate change on sea states. This project is part of the Sea State Climate Change Initiative research project funded by the European Space Agency (ESA). The Climate Change Initiative program aims to reprocess the archives of Earth Observations in order to reconstruct climate data records for a set of essential climate variables. Since 2018, the Laboratory for Ocean Physics and remote Sensing (LOPS) at Brest has been supervising the “Sea States” component of the CCI (scientific supervisor: Fabrice Ardhuin), which also involves 15 European partners (http://cci.esa.int/seastate) .
The researcher will use a new altimetry-based sea state dataset, currently produced at LOPS. This product benefits from numerous improvements (retracking algorithms, inter-calibration, denoising) developed within the framework of the Sea State CCI project, which improve the robustness of the long-term statistics. The study of the sea state variability will be carried out at the scale of the North Atlantic basin and will involve the statistical analysis of pressure and wind fields from the ERA5 reanalysis (ECMWF). This analysis will help improving our understanding of the sea state variability, by decoupling the natural and anthropogenic components of the signal, and to explore ocean-atmosphere interactions at multi-decade scales.
- PhD in physical oceanography, meteorology, climate science or an related field;
- knowledge on wave physics, sea states climatology, and/or multi-decadal climate variability;
- skills in statistical methods for the analysis of geo-spatial data, and programming languages (python, matlab and / or fortran);
- good communication skills (written and spoken English)
The project will be carried out at the Laboratory for Ocean Physics and remote Sensing (LOPS), at the IFREMER center in Britanny, France.
