Based on DHI operational Hydrodynamic 3D Model DKBS2hd model run results, a point dataset describing for each year the probability of a certain seabed location in the Baltic Sea being located below the deep halocline was created. The spatial coverage was the Baltic Sea. The spatial resolution was 5km. The temporal coverage was 20 years (2001-2020). The 2 rasters made available here result from interpolation of the point dataset, and represent 20-year probability (respectively average and standard deviation) values. The development of the original point dataset was funded by the EMODnet lot ÔÇÿSeabed HabitatsÔÇÖ for use in the development of the EUSeaMap product, more specifically in modeling the spatial distribution of the biological zones ÔÇÿcircalittoralÔÇÖ and ÔÇÿoffshore circalittoralÔÇÖ. According to the EUNIS habitat classification, in the Baltic Sea the circalittoral is above the halocline/pycnocline, while the offshore circalittoral is below.

The spatial coverage is the Baltic Sea. The spatial resolution is 5km. The temporal coverage is 20 years (2001-2020). The dataset is a point shapefile, the attribute table of which contains the following columns - 20 columns whose name is in the form p[yyyy] (e.g; p2001), where yyyy is the year: for the year yyyy, probability of the point location being located below the deep halocline - column ÔÇÿmeanÔÇÖ: probability average (i.e. average of the 20 yearly probabilities) - column ÔÇÿstdÔÇÖ: probability standard deviation across the 20 years The development of the original point dataset was funded by the EMODnet lot ÔÇÿSeabed HabitatsÔÇÖ for use in the development of the EUSeaMap product, more specifically in modeling the spatial distribution of the biological zones ÔÇÿcircalittoralÔÇÖ and ÔÇÿoffshore circalittoralÔÇÖ.

The substrate and nature type mapping was carried out for the Danish Nature Agency in the summer 2012. The survey included habitat classification of Limfjorden, Kattegat and The Belt Sea This studyarea is a part of The Belt Sea.

The objective of the study is to provide more information about the seabed for use in substrate and habitat classification. In the classification there have been used 2134 km of data with sonar, sediment echosounder and sidescan. Furthermore 4519 km seismic and acustic archive data from existing studies have been included in the analysis. The study area consist of Kattegat and the Belt Sea. This area is in the Little Belt.

This area lies in the south west Baltic Sea.
