This dataset comprises the annual count of chinstrap penguins arriving to Signy Island each breeding season, from 1996 to 2020. Penguins arriving at the beach in mid to late November (the austral summer) were counted. This monitoring contributes to the CCAMLR (Commission for the Conservation of Antarctic Marine Living Resources) Ecosystem Monitoring Program (CEMP) and is part of the annual seabird Long Term Monitoring carried out by the British Antarctic Survey at Signy Island. Ecosystems component of BAS Polar Science for Planet Earth Programme, funded by NERC.

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 datasets captures the body mass, bill length and bill depth of adult chinstrap penguins immediately after their arrival to Signy Island at the start of the annual breeding from 1996 to 2020. Penguins arriving at the beach were measured for bill length, depth, and body mass before being released where they were captured. These measurements were made in mid/late November, as chinstrap penguins arrive for the austral summer.

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.
