EMODnet Physics - TEMP_004 - Temperature monthly climatology for North Atlantic Ocean, Baltic Sea, Arctic Sea, Mediterranean Sea and Black Sea, covering the period from 1900 to 2014. This product is based on the SeaDataNet aggregated dataset v1.1.

Shapefile showing areas where ice concentration in the Barents Sea in 2018 was on average more than 20%. The 20% threshold was derived from WMO ice classification and corresponds to "Very open drift ice". Data averaged by Ifremer and NIVA derived from CMEMS (Copernicus) ice concentration product (resolution 1km, temporal resolution 1 year- 2018). Used in EUSeaMap 2019 as a proxy for the polar front affecting distribution of seabed habitats. Created by the EMODnet Seabed Habitats project consortium.

EMODnet Physics - Arctic Sea Ice Extend [2009 - ongoing] - Annual Max and Min contours. This product uses the Copernicus Marine Service product id. SEAICE_GLO_SEAICE_L4_NRT_OBSERVATIONS_011_001

This layer was created for the EUSeaMap 2019. It was computed from the CMEMS product "ARCTIC OCEAN - SEA ICE CONCENTRATION CHARTS - SVALBARD" (product identifier: SEAICE_ARC_SEAICE_L4_NRT_OBSERVATIONS_011_002). Daily values were averaged over the year 2018

The analysis was performed per season using DIVA software tool (Data-Interpolating Variational Analysis). The analyses products are stored as NetCDF CF files and made available as WMS layers for easy browsing and adding. Every step of the time dimension corresponds to a 6-year moving average from 1983 to 2016. The depth dimension spans from surface to 1000 m, with 21 vertical levels. The boundaries and overlapping zones between these regions were filtered to avoid any unrealistic spatial discontinuities. This combined water body dissolved oxygen concentration product is masked using the relative error threshold 0.5. Units: µmol/l Created by 'University of Liège, GeoHydrodynamics and Environment Research (ULiège-GHER)'. The data used as input for DIVA have been extracted from the EMODnet Chemistry Download Service: https://emodnet-chemistry.maris.nl/search Intermediate regional data products: Mediterranean Sea - DIVA 4D 6-year analysis of Water body dissolved oxygen concentration 1971/2017 v2018, Arctic Ocean - DIVA 4D 6-year analysis of Water body dissolved oxygen concentration 1980/2017 v2018, North Sea - DIVA 4D 6-year analysis of Water body dissolved oxygen concentration 1980/2017 v2018, Black Sea - DIVA 4D 6-year analysis of Water body dissolved oxygen concentration 1990/2016 v2018, North East Atlantic Ocean - DIVA 4D 6-year analysis of Water body dissolved oxygen concentration 1960/2017 v2018, Baltic Sea - DIVA 4D 6-year analysis of Water body dissolved_oxygen_concentration 1980/2016 v2018

A compliant implementation of WMS plus most of the SLD extension (dynamic styling). Can also generate PDF, SVG, KML, GeoRSS1

The MODIS marine chlorophyll a product provided, similar to SST, is a 4 km global monthly composite based on smaller resolution daily imagery compiled by NASA. The imagery is reliant on clear ocean (free of clouds and ice) so only months from March to October have been provided, as the chlorophyll levels in the Arctic diminish during the winter months, when sea ice is prevalent. The marine chlorophyll a is measured in mg/m3

Arctic mask shapefile produced by EMODnet Seabed Habitats as an input layer for the 2021 EUSeaMap broad-scale habitat model. Used in as a proxy to delimit the Arctic zone and it is used to classify shallow habitats into Arctic habitat classes as required by the EUNIS (V. 2019) habitat classification. The masks covers areas in the Barents Sea which are North of the polar front or where ice concentration exceeded 20% on average in 2018. The 20% threshold was derived from WMO ice classification and corresponds to "Very open drift ice". Created by the EMODnet Seabed Habitats project consortium.

Energy class layer produced by EMODnet Seabed Habitats as an input layer for the 2023 EUSeaMap broad-scale habitat model. The extent of the mapped area includes the Baltic Sea, and areas of the North Eastern Atlantic and Arctic extending from the Canary Islands in the south to Norway in the North. The map of energy classes was produced using underlying wave and current data and thresholds derived from statistical analyses or expert judgement on known conditions. This layer was updated in EUSeaMap 2023 using a new wave Kinetic energy at the seabed layer for the European Shelf area. A report on the methods used in the 2023 version of EUSeaMap and reports on previous versions (v2019 and V2021) are linked in Online Resources.
