Data were extracted from videos recorded during MEDSEACAN_2009 and CORSEACAN_2010 cruises operated by Comex (Aamp funding). Underwater vehicles were either Achille ROV or Remora submersible. Video analyses were realized by Ifremer and GIS posidonie.

Bathymétrie - Synthèse autour de l'île de Kerguelen, au pas de 200m.Ce MNT est une compilation de données issues de plusieurs campagnes océanographiques. Le MNT a été produit dans le cadre du programme EXTRAPLAC pour la délimitation du Plateau Continental au-delà des 200 M. Description des campagnes…

Sediment average grain size in the Mediterranean was generated from sediment categories. This rough granulometry estimate may be used for habitat models at meso- and large scale.

Bathymétrie - Zone du plateau de Saint-Pierre et Miquelon (SPMPLAC, 2011), au pas de 5 mètres. Le modèle bathymétrique est réalisé à l'aide des données de sondeur multifaisceau Simrad EM302 de la campagne SPMPLAC, acquises à proximité des îles. Objectif : couverture d'une zone de recherche de l'épave du Ravenel. Description de la campagne : SPMPLAC, R/V Le Suroît, 2011, https://doi.org/10.17600/11020060 La campagne est…

Distribution connue de corail noir (3 espèces d’Antipathaires : Antipathes dichotoma, Leiopathes glaberrima, Antipathella subpinnata) dans le canyon de Cassidaigne, Méditerranée Ouest. Les colonies de corail noir ont été filmées/photographiées au cours de la campagne VIDEOCOR1 par le H-ROV Ariane (L’Europe, 2017). Les images ont été utilisées pour réaliser des modèles 3D de chaque zone. Chaque colonie de Antipathella subpinnata a été positionnée…

Abundances were recoded in term of presence-absence. Geostatistical interpolation : the spatial variation of biological data were analysed using GENSTAT (GENSTAT 7 Committee, 2004), which is a GENeral STATistics package including the main geostatistical tools. It computes experimentala variograms, fits these with various authorised mathematical models and uses them to calculate kriged estimates on a fine regular grid (of latitudes and…
