The weight of Antarctic fur seal pups at Main Bay on Bird Island have been measured since 1973. 50 pups on the beach and 50 pups in the Tussac grass at the back of the beach are sexed and weighed in January, February and March each year. This work was funded by Natural Environment Research Council (UK) core funding to the British Antarctic Survey.

Platform Transmitting Terminal (PTT) tags have been used to track Antarctic Fur seals, (Arctocephalus gazella) from South Georgia, since 1998. PTT tags use the ARGOS satellite system to collect geospatial data. These tags are deployed on a project-by-project basis and so data are not available for every year. Tags are generally deployed during the summer season.

Since 2009, the weights of male and female Antarctic Fur Seal pups from the Maiviken area on South Georgia have been monitored. 100 pups are randomly sampled from two areas, tussock and beach, at the start of January, February and March. This work was funded by Natural Environment Research Council (UK) core funding to the British Antarctic Survey.

Counts of Antarctic fur seal individuals encountered daily at the Special Study Beach (SSB) at Bird Island, South Georgia. The SSB demographic study started in 1982 and has continued with consistent data collection methods to date. Daily values include total counts of territorial males, new females, all females present in the afternoon, new pups born, and number of dead pups. This work was funded by Natural Environment Research Council (UK) core funding to the British Antarctic Survey.
