The GHER is a research group of the University of Liège, directed by Professor J.-M. Beckers. It is devoted to marine and environmental study and modelling.

Initiated in the seventies in the frame of the Programme National mer by Professor J. Nihoul, the GHER participated in the study of many different sites such as the North Sea, the Black Sea, the Aral Sea, the South China Sea, the Bering Sea, the Persian Gulf or the Mediterranean Sea.

The Mediterranean primitive equation 3D hydrodynamic models were developed in the European projects EROS2000 and EUROMODEL, while the oceanographic data base and data analysis tools were elaborated during the European projects MERMAIDS, MODB, MEDAR and SeaDataNet and EMODNET (Chemistry).

Presently research activity focuses on merging of statistical data analysis and modeling into assimilation approaches (SANGOMA project), including nested coastal models. Model verification using wavelets and other advanced statistical tools is another research focus as well as cloud filling based on empirical orthogonal functions.

The GHER team is also responsible for the International Liège Colloquium on Ocean Dynamics which is close to its 50th edition, bringing 100-200 scientists to Liège each year.
