Data on physical impact intensity caused by trawling (bottom otter trawl, twin bottom otter trawl, dredges) estimated from VMS (Vessel Monitoring System) data cross-referenced with the Community Fishing Fleet Register and, for French vessels, with the landing data between 2008 and 2020. The data is constituted of 14 rasters in a resolution of 1’x1’ (13 annual abrasion rasters between 2008 and 2020 and 1 raster representing the 90th percentile of inter-annual abrasion). The abrasion is expressed in swept area ratio per year for each layer. This work enabled the study of the trawling impact on benthic communities in the Gulf of Lions and Corsica. The objective was to better describe the spatial and temporal repartition of trawling in this area and its potential impact on benthic habitats.

Cold-water coral habitat mapping in submarine canyons of the bay of Biscay was realized by the deep sea laboratory of Ifremer. Data came from the EVHOE 2009 cruise in the framework of the CoralFish project and as part of an agreement between Ifremer and the Agence des Aires Marines Protégées. The method was based on image analyses. Images were acquired using the towed camera « SCAMPI » during the EVHOE 2009 cruise (from 18/10/2009 to 01/12/2009, chief scientists: Jean-Pierre LEAUTE and Michèle SALAUN). Observed habitats were defined according to the CoralFish typology (J.S. Davies, B. Guillaumont, F. Tempera, A. Vertino, L. Beuck, S.H. Ólafsdóttir, C.J. Smith, J.H. Fosså, I.M.J. van den Beld, A.

Cold-water coral habitat mapping in submarine canyons of the bay of Biscay was realized by the deep sea laboratory of Ifremer. Data came from the BOBECO cruise in the framework of the CoralFish project and as part of an agreement between Ifremer and the Agence des Aires Marines Protégées. The method was based on video and image analyses. Videos and Images were acquired using the ROV Victor 6000 during the BOBECO cruise (from 9/09/2011 to 11/10/2011, chief scientists: Sophie Arnaud-Haond et Anthony Grehan). Observed habitats were defined according to the CoralFish typology (J.S. Davies, B. Guillaumont, F. Tempera, A. Vertino, L. Beuck, S.H. Ólafsdóttir, C.J. Smith, J.H. Fosså, I.M.J. van den Beld, A.
