Welcome to the Marine Geoscience website !

The Marine Geoscience research unit is committed to improving knowledge on the geological structures and processes of the deep seabed by exploring the continental shelf and the ocean depths and by participating in the technological developments necessary to fulfil these objectives.

Our research activities are conducted in a strong national, European and international collaboration context but also in partnership with industry and in support of public authorities.

Marine Geoscience Cartography

The Marine Geosciences Cartography portal displays thematic catalogs dedicated to geographical information produced by the Marines Geosciences unit of Ifremer.

Marine Science Videos Library

The objective of this portal is to give you access to recent video data produced during the Ifremer submersibles dives (Cyana, ROV Victor 6000 and Nautile).

French Oceanographic Cruises

The French Oceanographic cruises directory database lists all the scientific cruises which were carried out aboard French vessels or in cooperation with foreign vessels. This database currently contains the descriptions of more than 8,200 cruises (including mooring experiments, diving) made over the past century or so. Each year, about 200 new summaries from French organizations which operate the vessels IFREMER, IRD, CNRS/INSU, IPEV and chief scientists are added.

Oceanographic Data

L'Ifremer contribue à la connaissance des océans et de leurs ressources, à la surveillance du milieu marin et du littoral ainsi qu’au développement durable des activités maritimes. Dans ce cadre, l’institut opère ou participe à des systèmes d’observations variés : navires océanographiques et submersibles, observatoires automatisées (bouées, flotteurs), satellites, réseaux d’observateurs scientifiques ou d’observateurs volontaires (professionnels de la mer ou grand public). Tous ces systèmes produisent de nombreuses données sur l’état des océans qu’il faut ensuite classer, analyser et partager.
