CaribbeanSeaMap 2025 Broad-Scale Predictive Habitat Map

Output of the 2025 EUSeaMap broad-scale predictive model for the Caribbean region, produced by EMODnet Seabed Habitats.

The extent of the mapped area covers the jurisdictional waters of EU Member States and the United Kingdom (UK) in the Caribbean Sea

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 Seabed substrate

Biological zone is calculated using underlying physical data and thresholds derived from statistical analyses or expert judgement on known conditions.

The model is produced using R and ArcGIS Pro.

The model was created using raster input layers with a cell size of 0.00104dd (roughly 100 metres). The model includes the sublittoral zone only; due to the high variability of the littoral zone, a lack of detailed substrate data and the resolution of the model, it is difficult to predict littoral habitats at this scale.

For the Caribbean region EUSeaMap classified benthic broad habitat types are largely based on Andres et al. (2022) (linked in the Online Resources), which to our knowledge is the most comprehensive EUNIS-like classification of the Caribbean seabed habitats. Benthic broad habitat types are also described according to EUNIS 2022 classification level 2 and MSFD classification where possible.

An accompanying confidence layer is available for viewing and download from EMODnet Seabed Habitats - metadata is linked in the 'Composed of' section below.

A report on the methods used in the 2025 version of the CaribbeanSeaMap will be published in due course and the report on previous version (v2023) is linked in lineage.
