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

Species distribution
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. These VME fauna seem to have been swept away by repeated trawling. Vulnerable Marine Ecosystems (VME) in the deep Mediterranean Sea have been identified by the General Fisheries Commission for the Mediterranean as…

Distribution des colonies de Corallium rubrum (corail rouge) dans le canyon de Cassidaigne en 2017, Méditerranée Ouest

Species distribution
Distribution connue de corail rouge Corallium rubrum (Alcyonacea) dans le canyon de Cassidaigne, Méditerranée Ouest. Les colonies de corail rouge 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 Corallium rubrum a été positionnée à la main sur les modèles géoréférencés. Données liées à la publication…

Species and habitats - Syngnatidae - Larvae - All stages - IBTS Presence probability in January (2008-2011)

Species distribution
Fish larvae were collected during the night using a MIK (Methot Isaac Kidd) net (2m diameter, 500 um mesh). Abundances were expressed in term of number of individuals per 5000 cubic meter (ind.5000m-3). For clupeidae (herring and pilchard), gobiidae and ammodytidae, abundances were log-transformed (log10(x+1)) prior to analysis whereas for pleuronectidae and syngnathidae, abundances were recoded in term of presence-absence.

Species and habitats - Merlangius merlangus (Whiting) - Eggs - Abundance in January (IBTS, 2007) Kriging error

Species distribution
Biological data have been expressed in abundance (number of individuals per 20 m3). Kriging error (v) resulting from the interpolation of these data was maped.

Species and habitats - Loligo forbesi - All ages - Mean abundance in October, standard deviation maps during CGFS (1993-2009)

Species distribution
Biologic data have been expressed in abundance (numbers or density values (nbr/km²)) and always required to be log-transformed using a log10(x+1) transformation. Abundance mean (mean) and standard deviation (st) have been calculated.

Species and habitats - Sprattus sprattus - All ages - Recurrence - IBTS Q3 (1991-2010)

Species distribution
Species habitat occupation, observed during the third quarter IBTS from 1991 to 2010, has been expressed as rare, occasional, frequent, recurrent depending on density levels and variability over time.

Species and habitats - Ascidiacea - Presence probability (2006-2012)

Species distribution
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…
