A major goal of a research expedition by the Australian Antarctic Division over the summer of (2003/04) in the Southern Ocean off Heard Island was to answer some of the questions needed to determine what level of exploitation of Southern Ocean fisheries is sustainable. The use of novel equipment, cutting edge technology and some adept logistical co-ordination allowed the Aurora Australis, on the ... Southern Ocean, to catch the prey of the predators of Heard Island.
This work was accomplished by placing satellite trackers on animals at Heard Island, and then, using the ARGOS system, monitoring their activities in the Southern Ocean around the island. The Aurora Australis assisted in the monitoring and tracking of the animals by searching the areas the animals were foraging for prey species.
The animals tracked in this experiment were:
Light-mantled sooty albatrosses
Antarctic fur seals
An interactive map detailing the location and extents of a representative sample of the animals foraging trips is available at the url given below. An extract of all the positional data of the animals is not yet publicly available.
