Long term measurements of benthos composition in the Dutch national part of the North Sea. Samples have been taken by benthic sledge, box-corer, video and Hamon sampler. Samples were taken annually between 1991-2010, in 2012 and in 2015 and analysed to the genus or species level. For video sampling, coverage percentages were measured. The dataset has been used for assessment of the marine environment and habitat quality in the scope of the OSPAR Quality Status Reports and the Marine Strategy Framework Directive.

Long term measurements of phytoplankton composition in the Dutch national part of the North Sea. Samples were taken 12 - 24 times per year between 1990 and 1999 and analysed to the level of genus, species, or other taxon group. The dataset has been used for assessment of the marine environment and habitat quality in the scope of the OSPAR Quality Status Reports and the Marine Strategy Framework Directive. Currently, there are known issues concerning the quality of the data caused by changes in analytic procedures and labs. When more information is available, this will be published through EMODnet.

Long term measurements of phytoplankton composition in the Dutch national part of the North Sea. Samples were taken 12 - 24 times per year between 2000 and 2018 and analysed to the level of genus, species, or other taxon group. The dataset has been used for assessment of the marine environment and habitat quality in the scope of the OSPAR Quality Status Reports and the Marine Strategy Framework Directive. Currently, there are known issues concerning the quality of the data caused by changes in analytic procedures and labs. When more information is available, this will be published through EMODnet. The monitoring is directed and the dataset is maintained by Rijkswaterstaat, the executing body of the Dutch Ministery for Infrastructure and Environment. Publication of the dataset has been facilitated by Deltares, The Netherlands.

Oxygen regime class layer in the Black Sea produced by EMODnet Seabed Habitats as an input layer for the 2019 EUSeaMap broad-scale habitat model. The map of oxygen regime classes was produced using underlying potential density anomaly at the seabed and thresholds derived from statistical analyses or expert judgement on known conditions. Detailed information on the modelling process for the 2016 is found in the EMODnet Seabed Habitats technical report and its appendices (Populus et al, 2017, link in Resources). We are working on an updated report for the 2019 version.

Layer showing the boundaries used to subset the modelling of EUSeaMap (2019) therefore streamlining the processing. Each region had a specific partner lead within the consortium: Celtic seas & Arctic - JNCC Iberian peninsula & Black Sea - Ifremer Baltic sea - GEUS Mediterranean - ISPRA

Salinity regime class layer in the Baltic Sea and Kattegat strait. Produced by EMODnet Seabed Habitats as an input layer for the 2019 EUSeaMap broad-scale habitat model. The map of salinity regime classes was produced using underlying salinity data at the seabed and thresholds derived from statistical analyses or expert judgement on known conditions. Detailed information on the modelling process for the 2016 is found in the EMODnet Seabed Habitats technical report and its appendices (Populus et al, 2017, link in Resources). We are working on an updated report for the 2019 version.

Classified seabed substrate types for European seas. Produced by EMODnet Seabed Habitats as an input layer for the 2019 EUSeaMap broad-scale habitat model, based on EMODnet Geology seabed substrate products. The extent of the mapped area includes the Mediterranean Sea, Black Sea, Baltic Sea, and areas of the North Eastern Atlantic extending from the Canary Islands in the south to the Barents Sea in the north. The layer of seabed substrate was produced using data from EMODnet geology 1:100K, 1:250K and 1:1M seabed substrate maps, and integrated with extra substrate feature relevant for habitat mapping (seagrass beds, for example). The Folk 5 classification of substrate is adopted because it is compatible with the EUNIS classification of habitats used in EUSeaMap 2019. Detailed information on the modelling process for the 2016 is found in the EMODnet Seabed Habitats technical report and its appendices (Populus et al, 2017, link in Resources). We are working on an updated report for the 2019 version.

Energy class layer produced by EMODnet Seabed Habitats as an input layer for the 2019 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. Detailed information on the modelling process for the 2016 is found in the EMODnet Seabed Habitats technical report and its appendices (Populus et al, 2017, link in Resources). We are working on an updated report for the 2019 version.

Predictive Biological Zone layer produced by EMODnet Seabed Habitats as an input layer for the 2019 EUSeaMap broad-scale habitat model. The extent of the mapped area includes the Mediterranean Sea, Black Sea, Baltic Sea, and areas of the North Eastern Atlantic extending from the Canary Islands in the south to the Barents Sea in the North. The map of biological zone was produced using underlying physical data and thresholds derived from statistical analyses or expert judgement on known conditions. The model is produced in R and Arc Model Builder (10.1). The model was created using raster input layers with a cell size of 0.00104dd (roughly 100 meters). The model includes the sublittoral zone only (Infralittoral to Abyssal zone). Detailed information on the modelling process for the 2016 is found in the EMODnet Seabed Habitats technical report and its appendices (Populus et al, 2017, link in Resources). We are working on an updated report for the 2019 version.

Areas of high riverine inputs for EUSeaMap 2019 Biological zone model. The map cover the Adriatic Sea (Po river plume), east Mediterranean (Thessaloniki gulf and bay, the Maliakos gulf, and Geras gulf in the Aegean Sea) and the Black Sea (Dnieper-Bug river plume area). These were handled separately in the modelling process. This layer is one of several habitat descriptors used to model biological zone and habitat class. To establish the limit of these areas datasets on salinity and water temperature were used, where possible. Detailed information on the modelling process for the 2016 is found in the EMODnet Seabed Habitats technical report and its appendices (Populus et al, 2017, link in Resources). We are working on an updated report for the 2019 version.
