Output of the 2019 EUSeaMap broad-scale predictive model, produced by EMODnet Seabed Habitats and aggregated into the Benthic Broad Habitat Types of the Marine Strategy Framework Directive (as defined in the Commission Decision 17 May 2017).

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 was produced using a "top-down" modelling approach using classified habitat descriptors to determine a final output habitat.

Habitat descriptors differ per region but include:

- Biological zone

- Energy class

- Oxygen regime

- Salinity regime

- Seabed substrate

- Riverine input

Habitat descriptors (excepting Substrate) are calculated using underlying physical data and thresholds derived from statistical analyses or expert judgement on known conditions.
