Models Variables Description and derived metric Resolution Source SST climatological composites were used to generate four relevant metrics: annual maximum, minimum, mean and AVHRR pathfinder SST Sea surface the annual range (the difference 5 arcmin (version 5) available at temperature (SST) between maximum and minimum http://www.nodc.noaa.gov/ represent proxies of seasonality and temporal variation in SST) from the period 1982 to 2009 BEM Derived from the Bio- ORACLE dataset which is a high-resolution global Sea surface salinity Mean salinity monthly climatologies datasets designed for 5 arcmin (SSS) from the period 1961 to 2009 Species Distribution Model applications (Tyberghein et al., 2012) available at http://www.oracle.ugent.be/ Depth, slope and aspect were extracted from a Digital Elevation Model (DEM). The aspect was transformed into two The bathymetric elevation derived variables: Eastness (values data was derived from Seafloor close to 1 represent an eastward aspect, 90-meter source soundings collected topography while values close to –1 represent a by the INSTM referenced to westward aspect) and Northness the local tidal datum (values close to 1 represent a northward aspect, while values close to –1 represent a southward aspect). We reduced the original 15 seafloor types to 8 broad seafloor type as these Habitat modeling Habitat types represent relatively distinct physical environments supposed to Digital seafloor type data Seafloor type influence demersal marine species 90-meter was obtained from the distributions. We mapped the seafloor INSTM type by attributing to the centroid of each 0.0081 km² grid cell a seafloor category.
