UK Marine habitat classification (22.04) list

The Marine Habitat Classification for Britain and Ireland (Connor et al., 2004; Parry et al., 2015; JNCC, 2022) is based on the empirical analysis of benthic survey data, scientific literature, and consultation with marine experts. It describes the majority of the marine benthic habitats around the coasts and seas of Britain and Ireland. 

Available MarLIN information on habitats is listed below using the Marine Habitat Classification (v22.04) hierarchy.
