CNRS (Centre National de la Recherche Scientifique) is a public basic-research organization that defines its mission as producing knowledge and making it available to society. CNRS operates its own laboratories as well as joint research units (JRU) it maintains jointly with universities, other research organizations (e.g. IRD), or industry. CNRS laboratories are located throughout France and cover all fields of research. Scientists from three CNRS laboratories are involved in this project: CEREGE (European Centre for Research and Education in Environmental Geosciences) in Aix en Provence ; IPGS in Strasbourg ; ISTerre in Grenoble and LDO/IUEM (Laboratoire Domaines Océaniques, Institut Universitaire Européen de la Mer) in Brest. CNRS is primarily involved in WP 4, 7 and 8 and will contribute to data integration into WP3.
