Sediment substrate map at 1 : 250 000 of the French metropolitan EEZ produced in the work-package 3 of the European project EMODNet Geology, phase 2. And additionnal informations on index and confidence of original maps.

The In Situ Analysis System (ISAS) was developed to produce gridded fields of temperature and salinity that preserve as much as possible the time and space sampling capabilities of the Argo network of profiling floats. Since the first global re-analysis performed in 2009, the system has been extended to accommodate all types of vertical profile as well as time series. ISAS gridded fields are entirely based on in-situ measurements. The system aims at monitoring the time evolution of ocean properties for climatological studies and allowing easy computation of climate indices. A careful delayed mode processing of the 2002-2015 dataset has been carried out using version 7 of ISAS and updating the statistics to produce the ISAS-15 analysis.

This annual statistics at 500m horizontal resolution was produced from the archived time series of MARS 3D physics model hindcast runs along French Atlantic Coast. The variable that is available here is Temperature. Values are expressed in Celsius degrees. In each pixel the value is an average of the values of the 40 vertical levels that are considered in the model.

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 annual statistics at 500m horizontal resolution was produced from the archived time series of MARS 3D physics model hindcast runs along French Atlantic Coast. The variable that is available here is the Kinetic Energy induced by currents caused by tide, water density gradients and action of winds. The formula used for the Kinetic Energy calculation is 0.5mv², where m is the density of seawater (1027 kg.m-3) and v is the current-induced velocity. Values are expressed in N.m-2 (Newton per square meter). The vertical level is the seabed.

Map of average monthly non-algal suspended matter carried out in the period 2003-2010. TSS are estimated from the water reflectance using a specific algorithm developed at Ifremer.

Three environmental parameters were measured in situ during the REISE2 survey in April 1995. Temperature and salinity were measured using a probe. Fluorescence (mean for the water column) was measured using a fluorometer. This survey gives illustration of spring conditions.
