Data sustaining and diffusion

The CTDI group participates in sustaining and disseminating the scientific data of the Marine Geoscience research unit to the scientific community.

Oceanographic expedition data

The validated observation data are preserved in the various databases managed by the Sismer, National Centre of Oceanographic Data. The consistency of data from various horizons is thus ensured, as well as their sustainability and the pooling of IT developments. The final objective is to make the data available to the scientific community via the Marine Data Portal.

Validated bathymetric and seismic data


Data are accessible through the Web Portal that provides raw and validated data from oceanographic expeditions as well as synthetic products, according to the access rights of each cruise.

If you are unable to reach the data you are searching for, they may be subject to access restrictions (confidential data, too recent, or data acquired within a partnership…)

A reflexion on the storage of data from other equipment is in progress (piezometer, seismic ...).

Video data

These data are accessible through the Web Portal of Marine Sciences Videos.

They are specific scientific data. They have been collected during Ifremer submersible dives. These data are numerous, voluminous and diverse (submersible type, storage medium…)



Logbook data are accessible through the Ifremer Archives Portal.

They relate day to day characteristics and events of each oceanographic expedition. Original logbooks in paper format are now digitised and available to the scientific community.

Geographic data

Seabed mapping products elaborated by Ifremer are available to the scientific community and the public through Ifremer’s Geographic Data Infrastructure Sextant.

They represent the geographical objects resulting from the research work of the Marine Geoscience research Unit, such as, for example, numerical models of bathymetry terrain, acoustic imaging mosaics, scanned and vectored surface formation maps or geological maps.
