Broadscale Subtidal Biotope Mapping to the West of the Outer Hebrides, Scotland, UK 2009


This project aimed to map the broadscale biotopes and habitats of the rocky reef sites west of the Outer Hebrides through integrating various survey data and facilitated through the use of GIS.

Acoustic remote sensing, video ground-truthing and grab sampling were integrated within a Geographical Information System (GIS) to derive benthic habitat maps for five survey sites off the western Outer Hebrides (west and south-west of the island of Barra). The surveys targeted potential bedrock reef areas, which are a habitat listed under the EC Habitats Directive, at the inshore-offshore waters boundary (12 nm from the coast). Background data were limited for these sites due to their distance offshore, and therefore acoustic remotely sensed data were gathered in order to generate bathymetries for each site for use in stratifying the video surveys and to ensure bedrock reef was targeted.
