Funiculina quadrangularis (Pennatulacea) presence and absence extracted from video, from Fabri et al, 2014

Soft mud facies with Funiculina quadrangularis is an essential habitat for certain crustacean species (Parapenaeus longirostris and Nephrops norvegicus). These habitats are potentially vulnerable as they are targeted by fisheries.Vulnerable Marine Ecosystems (VME) in the deep Mediterranean Sea have been identified by the General Fisheries Commission for the Mediterranean as consisting of communities of Scleractinia (Lophelia pertusa and Madrepora oculata), Pennatulacea (Funiculina quadrangularis) and Alcyonacea (Isidella elongata). This dataset concerns video data recorded in the heads of French Mediterranean canyons. Quantitative observations were extracted from 101 video films recorded during the MEDSEACAN cruise in 2009 (Aamp/Comex), in addition to four other cruises (two Marum/ Comex cruises in 2009 and 2011 and two Ifremer cruises in 1995 and 2010). Species recognized in the video films were recorded from 180 to 700 m depth, and were mapped using GIS.Funiculina quadrangularis was rarely observed, being confined for the most part to the Marti canyon (Hérault).This dataset is linked to the pulication Fabri et al, 2014. https://doi.org/10.1016/j.dsr2.2013.06.016
