Broad scale habitat types (HOLAS 3)

Data represent the presence/absence distribution of Broad Habitat types (BHT) in the Baltic Sea. The data is based on the EUSeaMap 2021 data, downloaded from EMODnet Seabed Habitats thematic portal (https://emodnet.ec.europa.eu/en/euseamap-2021-emodnet-broad-scale-seabed-habitat-map-europe). The dataset includes an ecosystem component raster layer for all 18 habitat types listed under MSFD BHT in the original EUSeaMap dataset, excluding the habitat “NA” where the classification was not applicable. The habitats are formed by combining the biological zone (infralittoral/circalittoral / Offshore circalittoral) and substrate information (coarse, mixed, mud, sand, mud or sand, rock and biogenic reef), forming altogether 18 layers. Original vector data was transformed to 1x1km grid rasters, one data set for each BHT.
