Measures of feeding activity in 17 species of shallow water marine benthos, as assessed visually by SCUBA divers. The aim of the study was to determine the seasonal and interannual variability in feeding activity. Data were taken once or twice a month over the period from October 1997 to May 2005. Not all species were monitored for the entire duration of the study, and the number of observations per species ranged from 21 to 133.

This dataset captures information on the diet composition and mass of chinstrap penguin stomach contents at Signy Island, from 1997 to 2020. The monitoring period occurred over four weeks each year and involved sampling adults returning to feed their chicks during the creche period. Sampling took place approximately every five days. Numbers of birds sampled on each occasion varied over the entire period of the dataset from a maximum of eight to a minimum of six, equating to an annual maximum of forty birds and an annual minimum of thirty, depending on the year. All adult penguins were sampled on their return to the colony using the stomach lavage methodology specified in CCAMLR CEMP Standards Methods A8A. The stomach samples were then weighed and categorised into krill, cephalopods, fish and non-food and identified to species level where possible. Krill carapaces and otoliths were removed and measured. Ecosystems component of BAS Polar Science for Planet Earth Programme, funded by NERC.

This dataset captures information on the diet composition and mass of gentoo penguin stomach contents at Signy Island, from 1998 to 2010. The monitoring period occurred over four weeks each year and involved sampling adults returning to feed their chicks during the creche period. Sampling took place approximately every five days. Numbers of birds sampled on each occasion varied over the entire period of the dataset from a maximum of eight to a minimum of six, equating to an annual maximum of forty birds and annual minimum of thirty, depending on the year.

This dataset captures information on the diet composition and mass of Adelie penguin stomach contents at Signy Island, from 1997 to 2020. The monitoring period occurred over four weeks each year and involved sampling adults returning to feed their chicks during the creche period. Sampling took place approximately every five days. Numbers of birds sampled on each occasion varied over the entire period of the dataset from a maximum of eight to a minimum of six, equating to an annual maximum of forty birds and an annual minimum of thirty, depending on the year. All adult penguins were sampled on their return to the colony using the stomach lavage methodology specified in CCAMLR (Commission for the Conservation of Antarctic Marine Living Resources) Ecosystem Monitoring Program (CEMP) Standard Methods A8A. The stomach samples were then weighed and categorised into krill, cephalopods, fish and non-food and identified to species level where possible. Krill carapaces and otoliths were removed and measured. Ecosystems component of BAS Polar Science for Planet Earth Programme, funded by NERC.

This dataset captures information from GPS and Time-Depth Recorder (TDR) tracking of 221 chinstrap penguins from 4 sites at the South Orkney Islands (Cape Geddes at Laurie Island, Powell Island, Monroe Island and Signy Island). Monitoring was carried out during incubation and brood between the months of December and February from 2011 to 2016. GPS data are available at 4 minute intervals whilst birds are at the sea surface and dive data every second. Tags measured birds'' foraging patterns to study the relationship between breeding stage and foraging distribution. This research was supported by the Darwin Plus, WWF and the UKRI/BAS Ecosystems Programme under ALI-Science.

This annotated dataset comprises locational data of beluga whales along the eastern shore of the Yugor Penisula and in the inner part of Baydaratskaya Bay in the southern Kara Sea (Russia) as detected from Very High Resolution (VHR) satellite imagery on July 4th and 9th, 2016. Images were manually scanned and whales detected through the use of grids. Additional metadata includes information on image type and model, and whale distinctive characteristics (e.g., fluke or blow). This work supports the ''training'' of machine learning algorithms for automatic detection of whales from satellite imagery. This study was possible thanks to imagery support from MAXAR Technologies/Digital Globe Foundation for the VHR images and core funding from British Antarctic Survey, Natural Environment Research Council, as part of the ''Wildlife from Space'' project.

We tracked 94 common and 50 Brunnich''s guillemots from five colonies around Iceland (Latrabjarg, Grimsey, Langanes, Skrudur and Papey) during late incubation and chick rearing from June to July 2019. We also tracked 5 common and 3 Brunnich''s guillemots from Langanes during chick-rearing in July 2020 (GPS only). Finally, we tracked 4 common and 4 Brunnich''s guillemots from Langanes during late incubation and chick rearing in June 2021. We used Pathtrack nanoFix GPS loggers to record locations every 3min and Cefas G5 TDR loggers to record depth every second. The tags recorded the birds'' behaviour for a few days (typically 2 to 3). The aim was to investigate the foraging behaviour of the two species and the potential competition between them. Funding was provided by NERC grant NE/R012660/1 (part of the NERC Changing Arctic Ocean programme).
