  • Platform Transmitting Terminal (PTT) tags were used to track Antarctic Fur Seals (Arctocephalus gazella) from Bird Island, South Georgia, 1995-2010. PTT tags use the ARGOS satellite system to collect geospatial data. Tags were deployed on breeding females during the summer, to provide information on where the seals are foraging during lactation and into the winter months.

  • Fur Seal (Arctocephalus gazella) diet has been monitored at the King Edward Point research station on South Georgia since 2008. Scats are collected regularly and krill carapaces, fish otoliths and squid beaks extracted. Krill length is calculated from the extracted carapaces whilst squid beaks and fish otoliths are measured and identified to species where possible. This dataset comprises raw and processed krill length as well as squid beak and otolith measurements and identification to species where appropriate.

  • Fur Seal (Arctocephalus gazella) diet has been monitored at Bird Island since 1989. Scats are collected regularly and krill carapaces, fish otoliths and squid beaks extracted. Krill length is calculated from the extracted carapaces whilst squid beaks and fish otoliths are measured and identified to species where possible. This dataset comprises raw and processed krill length as well as squid beak and otolith measurements and identification to species where appropriate.

  • At-sea surveys of seabirds around South Georgia were undertaken during the austral winter (May to September) in 2010 and 2011. Surveys were conducted in set transects which covered areas primarily targeted by the krill industry, and as well as areas not normally fished. Surveys consisted of simultaneous recordings of seabirds and marine mammals on the surface of the water within a continuous 300m wide strip transect on one side of the vessel, and ''snapshots'' at 300m intervals. Species, positional, environmental and trip data were recorded for each survey. The aim of the project was to investigate the potential interactions between higher predators and the South Georgia krill fishery. These surveys were carried out as part of a wider Overseas Territories Environment Programme (OTEP; SGS701) funded project ''Identifying important and vulnerable marine areas for conservation at South Georgia.'' Phil Trathan (BAS) applied for this grant.

  • 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.
