Imagery and crabeater seal point locations from aerial surveys of Crystal Sound and Marguerite Bay, West Antarctic Peninsula 2015

This dataset comprises of vertical aerial imagery of sea ice in Marguerite Bay and Crystal Sound in 2015, the point locations of ice seals detected in that imagery, and polygons denoting the area of the surveys. It was done initially to test the possibility of counting ice seals in aerial and satellite imagery and will be used in future as a baseline dataset to track ice seal abundance in the region. The points were manually digitised in ArcGIS by one observer.

The original imagery was taken by operators from the BAS Mapping And Geographic Information Centre. Counting and analysis was part of the NERC grant NE/W009641/1.
