The mapping of pockmark habitats (cold fluid emissions) off the coast of Congo was carried out by Ifremer's Deep-Sea Laboratory as part of the WACS cruise. The method used for this habitat mapping is based on the preliminary analysis of videos acquired with the ROV Victor 6000 during the oceanographic cruise: WACS (from 26/01/2011 to 25/02/2011, mission leader: Karine OLU). The habitats were described at the finest level of analysis and then classified according to the EUNIS typology (https://www.eea.europa.eu/data-and-maps/data/eunis-habitat-classification-1).

Distribution of catch from deep-sea impacting fishing on the North Atlantic (18°N to 76°N and 36°E to 98°W), for the period 2010-2015. The average of yearly fishing catch for the period 2010-2015 is displayed as an index on the ATLAS grid of 25km * 25km resolution. Source data originated from the Global Fisheries Landings V4.0 database. The dataset was filtered to select only the fishing gears that have an impact on large areas of the seafloor (dredges, bottom trawls, and Danish seines). Within each cell, all remaining catch records were summed to get the total catch rate of the considered year. This dataset was built to feed a basin-wide spatial conservation planning exercise, targeting the deep sea of the North Atlantic. The goal of this approach was to identify conservation priority areas for Vulnerable Marine Ecosystems (VMEs) and deep fish species, based on the distribution of species and habitats, human activities and current spatial management.

This data set was obtained during 2 ENVISION-IFREMER field campaigns carried out in 2007 and 2011, to sustain a R & D project aimed to develop pectinid aquaculture. This project was co-funded by the St Pierre et Miquelon public collectivity and ODEADOM. This represents a synthesis of spatial analysis based upon multi-criteria to assess future seeding and rearing areas for King scallop Placopecten magellanicus on the Eastern coast of Saint Pierre et Miquelon.

This data set was collected during 2 ENVISION-IFREMER field campaigns carried out in 2007 and 2011 to sustain a Pectinid aquaculture project. This was co-funded by ODEADOM and the public collectivity of Saint Pierre et Miquelon. This work aims to assess new seeding and rearing areas for the King scallop Placopecten magellanicus through a site selection process using the bottom type mapping data set obtained during the 2 ENVISION-IFREMER field campaigns. Furthermore, new estimates of potental scallop production is produced by this data treatment.

The mapping of habitats off the coast of Congo was carried out by the Ifremer Deep-Sea Laboratory as part of the ANR CONGOLOBE project (2011-2015, coordinator Christophe RABOUILLE). The method used for this habitat mapping is based on the preliminary analysis of images acquired with the ROV Victor 6000 during two oceanographic campaigns: WACS (from 26/01/2011 to 25/02/2011, mission chief: Karine OLU) and CONGOLOBE (from 11/12/2011 to 12/01/2012, mission chief: Christophe RABOUILLE). The habitats were described at the finest level of analysis and then classified according to the EUNIS typology (https://www.eea.europa.eu/data-and-maps/data/eunis-habitat-classification-1).

Data represents percentage cover of kelp forest as well as biomass of the 2 main species: L. digitata and L. hyperoborea. The used approach consists in firstly establishing surveys and appropriate processing methods in order to provide a detailed underwater topography of the area and to accurately delineate hard substrates (bedrock) potentially colonized by kelp. Secondly, a habitat suitability model is fitted for each species on some carefully selected field stations, measuring kelp presence/absence and biomass. Predictive maps are produced, based on hard substrate areas previously delineated.

The term "boulder fields" covers areas of boulders of the lowest levels of the foreshore which are uncovered during low tides. They are not really part of the mediolittoral (intertidal zone) but what is now defined as the fringe tip (or emerging or upper part) of the infralittoral. More generally, boulder fields, formed by the fragmentation of the rocks in place, are located at the foot of rocky cliffs or between rocky headlands and flats. They are only accessible on foot during tidal coefficients greater than or equal to 95. Boulder fields naturally harbor a high biodiversity due to their position at the bottom of the foreshore, but the wealth of fauna and flora also depends greatly on the type of architectural habitat. Three broad categories of boulder fields are distinguished: Sediment blocks, blocks of bedrock and blocks on blocks.

Map of benthic habitat synthesis of the Natura 2000 site FR5300015 - Bay of Morlaix is the result of the fusion and harmonization of five cartographic data. They were generated according to mapping strategies, interpretation scales and on the basis of different cartographic supports.
