Abstract

This report provides an update to the Shetland Islands Dominant Marine Biotope Map (SI-DMBM), a predictive benthic model covering 28 biotopes (Level 4) within Shetland waters out to 12 nm. This latest update includes several methodological improvements; upgraded modelling framework using MaxEnt implemented in R and additional validation metrics. It also provides an updated estimate of potential blue carbon storage within the predictive sediment layer, originally assessed in 2025.
