Molecular species identification of historical whale remains from South Georgia
The island of South Georgia is located at the southern extreme of the South Atlantic Ocean, on the edge of the Southern Ocean that surrounds Antarctica. Intensive commercial whaling at South Georgia began in 1904, when the first land-based whaling station was built in Grytviken (54°17′S, 36°30′W). F...

The island of South Georgia is located at the southern extreme of the South Atlantic Ocean, on the edge of the Southern Ocean that surrounds Antarctica. Intensive commercial whaling at South Georgia began in 1904, when the first land-based whaling station was built in Grytviken (54°17′S, 36°30′W). Five other shore stations were eventually built: Ocean Harbour (54°20′S, 36°16′W), Leith Harbour (54°08′S, 36°41′W), Husvik Harbour (54°18′S, 36°71′W), Stromness Harbour (54°90′S, 36°41′W), and Prince Olav Harbour (54°40′S, 36°90′W). Another site, Godthul (54°17′S, 36°17′W), was used as a protected anchorage for floating factories. By 1965, when shore-based whaling activity ceased, over 175,000 whales had been processed on the island (Moore et al. 1999).
