CaribbeanSeaMap 2025 Broad-Scale Predictive Habitat Map - Confidence in Classification of Biological Zones (Habitat Descriptor)

Confidence in the classification of biological zones in the 2025 CaribbeanSeaMap broad-scale predictive habitat map, as there were no changes to the biological zones in the 2025 update the confidence remains the same as the 2023 version.

Values are on a range from 1 (Low confidence) to 3 (High confidence).

Biological Zone is one of the layers of information used to categorise physical habitat types in CaribbeanSeaMap; these layers of information are collectively known as 'habitat descriptors'. Confidence in the classification of a Biological Zone at any location is driven by both the confidence in the values of the input variables, and the confidence in the classification based on proximity to, and uncertainty in, the boundary between classes (i.e. areas closer to a boundary between two classes will have lower confidence).

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.
