The Beam Trawl Survey dataset includes age- and length-based catch per unit effort data for commercial fish species in ICES statical rectangles.

A detailed distribution of true crabs (Brachyura) in the North-East Atlantic.

This dataset consists of casual observations reported by members of the public.

Records collected voluntarily and uploaded via indicia based web recording sites including iSpot, Irecord, Marine Sightings Network and Sealife Survey. iSpot records are recorded by members of the public wishing to have identifications confirmed and records from iRecord and the MBA Recording scheme are reported sightings from a wide range of recorders.

Occasional sighting of marine species recorded by academics, professionals or expert amateur naturalists.

"Intertidal species, effort based search undertaken by students (16+) and volunteer groups with support from an ecologist. During the twenty minute timed species search surveyors look for 22 species, 4 non native and 18 climate change indicator species within 1 of 3 habitats rockpools; boulders, crevices and overhangs; or open rock. Abundance is recorded using a simplified version of SACFORN. "

Phytobenthos community data, a large portion of the data held are monitoring data submitted for the OSPAR CEMP and HELCOM COMBINE monitoring programmes and therefore follow specific monitoring programme guidelines.

The dataset includes age- and length-based catch per unit effort data for commercial fish species collected by the French Channel Groundfish Trawl Survey.

<p>The dataset includes age- and length-based catch per unit effort data for commercial fish species collected during the Scottish Rockall Survey. This is a new survey from 2011, replacing historical ROCKALL survey in DATRAS.</p>

<p>3-D habitat suitability maps (HSM) or probability of occurrence maps, built using Shape-Constrained Generalized Additive Models (SC-GAMs) for the 30 main commercial species of the Atlantic region.</p><p>Predictor variables for each species were selected from: sea water temperature, salinity, nitrate, net primary productivity, distance to seafloor, distance to coast, and relative position to mixed layer depth. Each species HSM contains 47 maps, one per depth level from 0 to 1000 m. Probability values of each map range from 0 (unsuitable habitat) to 1 (optimal habitat). For depth levels below the 0.99 quantile of the depth values found on the species occurrence data, NA values were assigned. Maps have been masked to species native range regions. See Valle et al.
