Sentinel2 satellite imagery and derived geographic locations of emperor penguin colonies in the central and eastern Bellingshausen Sea between October and December, 2022
This dataset comprises Sentinel2 satellite imagery and derived geographic locations of five emperor penguin colonies located in the central and eastern Bellingshausen Sea, between October to December 2022. Medium-resolution satellite data was monitored for the presence of emperor penguin colonies, and when colonies were found, imagery was digitised and downloaded from Copernicus playground. Satellite data indicate early sea ice break-up at three of the four colonies, and the disappearance of the fourth colony.
Digitisation and annotation of satellite imagery was carried out by the British Antarctic Survey, and supported by NERC core funding and WWF grant NEB 2181.

Quality of the count data should be regarded as approximate as the methodology of counting numbers of birds from VHR imagery is unproven and although counters get agreement within 5-20 percentage any bias to as yet untested. See related paper.
The following jpeg''s imagery is only partially loaded. This has not affected the quality of the dataset and associated locations of emperor penguin colonies.
