Research projects

Our main ongoing research projects are :

Project funded by the Make Our Planet Great Again program. Principal investigators : W.K. Dewar (Florida State University) and MEOM scientists. Collaborations in LOPS (Brest) and LMD (Paris).

This project aims to prepare numerical ocean models for the next generation Copernicus Marine Environment Monitoring Service (CMEMS). In response to the future priorities for CMEMS, IMMERSE will develop new capabilities to enable the production of ocean forecasts and analyses that exploit upcoming high resolution satellite datasets ; deliver ocean analyses and forecasts with the higher spatial resolution and additional process complexity demanded by users ; exploit the opportunities of new high performance computing (HPC) technology ; allow easy interfacing of CMEMS products with detailed local coastal models. These developments will be delivered in the NEMO ocean model, an established, world-class ocean modelling system that already forms the basis of the majority of CMEMS analysis and forecast products.

The goal of BOOST-SWOT is to design new algorithms able to provide altimetry-derived SSH gridded products resolving at least the upper spectrum of the sub-mesoscale dynamics (> 50 km), incorporating SWOT data expected in 2021.

Turbulent ocean models spontaneously generate a chaotic variability reaching multi­decadal/basin scales. How this low­-frequency chaos impacts climate-relevant oceanic indices is an important unsettled question. To separate this chaos from the atmospherically-forced response, MEOM and CERFACS have performed a pioneering 50-member ensemble of 1/4° global ocean/sea-ice simulations (1960-2015), which were perturbed initially but driven by the same atmospheric evolution. The results reveal the importance of the oceanic chaos, its large spatiotemporal scales, its its modulation by the atmosphere, and raise new issues about the detection/attribution of climate change in the ocean and the potential impact of this low-frequency chaos on the atmosphere.

DRAKKAR is a scientific and technical coordination between French research teams (LEGI-Grenoble, LPO-Brest, LOCEAN-Paris), MERCATOR-ocean, NOC Southampton, IFM-Geomar Kiel, and other teams in Europe and Canada. We propose to design, carry out, assess, and distribute high-resolution global ocean/sea-ice numerical simulations based on the NEMO platform (www.nemo-ocean.eu) performed over long periods (five decades or more), and to improve and maintain a hierarchy of state-of-the-art ocean/sea-ice model configurations for operational and research applications.

The vision of AtlantOS is to improve and innovate Atlantic observing by using the Framework of Ocean Observing to obtain an international, more sustainable, more efficient, more integrated, and fit-for-purpose system. Hence, the AtlantOS initiative will have a long-lasting and sustainable contribution to the societal, economic and scientific benefit arising from this integrated approach. This will be achieved by improving the value for money, extent, completeness, quality and ease of access to Atlantic Ocean data required by industries, product supplying agencies, scientist and citizens.
