EUSeaMap (2023) Broad-Scale Predictive Habitat Map for the Caspian- Biological zones (a habitat descriptor)
Description
Predictive Biological Zone layer produced by EMODnet Seabed Habitats as an input layer for the 2023 EUSeaMap broad-scale habitat model for the Caspian region. The extent of the mapped area includes the Caspian sea. 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).
The biological zones include:
Infralittoral
Offshore circalittoral
Circalittoral
Bathyal
Abyssal
An accompanying confidence layer is available for viewing and download from EMODnet Seabed Habitats.
