Antarctic Fur Seal foraging trip duration, Bird Island, South Georgia from 1978 onwards

Since 1978, female Antarctic Fur Seal foraging trip duration has been monitored on Bird Island, South Georgia. Each year 20 female Fur Seals are tagged with a VHF transmitter. Disruptions to the transmitter's signal indicate the seal is at sea and thus foraging trip time can be calculated. Data is available for individual seals as well as average, minimum and maximum trip times for each season. This data is collected as part of the Commission for the Conservation of Antarctic Marine Living Resources's Marine Debris Programme (CCAMLR CEMP).
