Raw seismic reflexion data collected on board of the French oceanographic fleet managed by IFREMER and archived at SISMER.

French national archive (SISMER) of time series data, particularly current meter and thermistor data.

The dataset includes age- and length-based catch per unit effort data for commercial fish species collected by the French trawl survey EVHOE.

Reflectivity measurements of the multibeam echosounders of the French Research Vessels

Validated and aggregated data from current profilers measured continuously by hull-mounted ADCPs (Acoustic Doppler Current Profiler).

The ORHAGO cruises (Observation of the benthic aquatic resources of the GOlfe de Gascogne) are part of Ifremer's mission of observation and expertise in support of fisheries management. Their main aim is to obtain series of abundance indices for flatfish and in particular for sole. Consequently, the choice was made to adopt a beam trawl to comply with the standards of the International Council for the Exploration of the Sea (ICES) for flatfish. This choice has made it possible to be part of the campaigns coordinated by ICES and thus to be a member of a community in which the methodology and results can be discussed each year in the ICES WGBEAM working groups. Since 2013, the ORHAGO campaigns have been used to assess the state of the Bay of Biscay sole stock. They allow this assessment to be carried out analytically, i.e. using a model to analyse and simulate the dynamics of the stock. The ORHAGO campaigns are also a source of information on the evolution of benthic populations and coastal benthic habitats in the Bay of Biscay.

Localisation of marine geological and biological samples, stored in the biology and geology ocean database managed by IFREMER (BIGOOD, BIology and GeOlogy Ocean Database).

The 62 RESSGASC campaigns allow the quarterly assessment of the quantities of various species (hake, sole, Norway lobster, etc.) discarded by fishing vessels (individuals below legal landing size). This information, together with data collected from the demographic structure of landings (using samples from auctions), is essential for the evolution of commercial fish stocks.
