Aerial surveys and annotated counts of black-browed and grey-headed albatrosses in their colonies across South Georgia during the 2023/2024 season

This dataset comprises aerial surveys using remotely piloted aerial systems (RPAS) and derived annotations of albatrosses in colonies across South Georgia during the 2023/2024 season (austral summer). The dataset includes stitched orthomosaics and digital surface models (DSM), as well as annotated counts of black-browed and grey-headed albatrosses during their breeding season. Counts are assigned to respective colonies within larger sites.

Surveys were conducted as part of an all-island albatross survey carried out every 10 years to monitor albatross trends across South Georgia. Flights were conducted by personnel at BAS and supported by the MV SG Pharos. This project was funded by the following: Friends of South Georgia Island, South Georgia Heritage Trust, Antarctic Research Trust, Peter Smith Charitable Trust for Nature, UK Blue Belt Programme.
