ABSTRACTDeception Island in the South Shetland Islands was the site of some of the earliest commercial activity to be carried out in the Antarctic with the early 19th century hunting of Antarctic fur seals. Nearly a century later it was the site of the most extensive anchorage for the reconstructed ships and ocean liners used as non-pelagic whale processing factories. Deception was also the site of what is the only successful land based commercial activity in Antarctic history. The Hektor whaling station operated in Whalers Bay from 1912 until 1931. Most of the remains of the station have now been obliterated by the volcanic activity that occurred in the late 1960s and 1970. By the later part of the twentieth century Deception Island had become a regular stop for the growing Antarctic tourist cruise industry. No other place in Antarctica has been so thoroughly identified with commercial activity.

Antarctic marine ecosystems undergo enormous changes, presumably due to climate change and fishery. Unmanned aerial vehicles (UAVs) have an unprecedented potential for measuring these changes by mapping indicator species such as penguins even in remote areas. We used a battery-powered fixed-wing UAV to survey colonies along a 30-km stretch of the remote coast of southwest King George Island and northwest Nelson Island (South Shetland Islands, Antarctica) during the austral summer 2016/17. With multiple flights, we covered a total distance of 317 km. We determined the exact position of 14 chinstrap penguin colonies, including two small unknown colonies, with a total abundance of 35,604 adults. To model the number of occupied nests based on the number of adults counted in the UAV imagery we used data derived from terrestrial time-lapse imagery. The comparison with previous studies revealed a decline in the total abundance of occupied nests. However, we also found four chinstrap penguin colonies that have grown since the 1980s against the general trend on the South Shetland Islands. The results proved the suitability of the use of small and lightweight fixed-wing UAVs with electric engines for mapping penguin colonies in remote areas in the Antarctic.

South Shetlands

The South Shetland Islands were discovered in 1819. Almost immediately the fur seal population was intensively exploited and this lasted through the early years of the 1820s, by which time seal numbers had been so depleted that sealing became uneconomic. Sealing was revived for both fur seals and Elephant seals at several periods later in the century. Sealers were put ashore in gangs and built makeshift shelters in which to live. Many of these have been identified on the South Shetlands, and a number have been excavated, though few with archaeological method. Fifty known sites are identified. The paper outlines the survey and excavation of two sites on Rugged Island by archaeologists from Australia and from the Chilean National Natural History Museum. One site relates to the sealing era of the 1820s, while the second may be associated with a marooned sealing gang in the 1870s. The nature of the occupation sites on the South Shetlands is analysed in relation to the social and operational context of the merchant navies of Britain and the USA in the nineteenth century. This is seen as a more directly relevant context for assessing physical evidence than is the application of theories of global capitalist systems.
