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.

Aerial survey of St Andrews Bay elephant seal colony, Mirounga leonina, during the 2023/24 season conducted using a remotely piloted aerial system (RPAS). The aerial survey was conducted as part of the Darwin Plus (DPLUS) 214 project: Southwest Atlantic Elephant Seal Population Assessment (SAESPA). Dataset includes the original images and log files, the original RINEX GNSS (global navigation satellite system) base station files, the post-processed global navigation satellite system and imagery data, along with the resulting georeferenced DSM (digital surface model) and an orthorectified mosaic of the imagery. This dataset is from flight number DPLUS_214_26 which was carried out on 2024-10-30. This work was supported by the Overseas Territories Environment and Climate Fund under Grant Darwin Plus ref: DPLUS214: Southwest Atlantic Elephant Seal Population Assessment (SAESPA).
