Common/harbour seal (Phoca vitulina) - Orkney and North Coast - fine-scale at sea usage map
This map layer has been supplied directly by Marine Scotland National Marine Plan interactive. You can obtain additional information about the layer on this page
This layer is displays a fine scale common/ harbour seal (Phoca vitulina) at sea usage map. These ‘usage’ maps are produced by looking at movement data from telemetry tagged seals between 2003 and 2015. The resulting patterns of usage are scaled to population levels using data collected in aerial survey counts at haul-out sites, to produce estimates of mean density at a spatial resolution of 0.6 km x 0.6 km grid cells.
Alongside these maps, a report is available at (https://data.marine.gov.scot/dataset/fine-scale-harbour-seal-sea-usage-mapping-around-orkney-and-north-coast-scotland), that describes how fine-scale harbour seal usage maps around Orkney and the north coast of Scotland can be used and interpreted, as well as the caveats and limitations, and methodology used to produce them.
