Analysis of information sources in references of the Wikipedia article "South Georgia and the South Sandwich Islands" in English language version.
There are no permanent residents in the Territory but the British Antarctic Survey (BAS) operates two bases on South Georgia. The base at King Edward Point (KEP) is operated under contract to GSGSSI and the FCO and is staffed by eight BAS personnel, plus two GSGSSI officers and their spouses. Bird Island has a year round complement of four BAS personnel who undertake long-term monitoring of seabirds and marine mammals. The South Sandwich Islands are uninhabited, though an originally undetected, and subsequently allowed, manned Argentinean research station was located on Thule from 1976 to 1982.
The area is often cloudy, and a seemingly constant volcanic plume conceals the lake most of the time. Fortunately, the team collected enough shots of the lake from 2003 to 2018 that clearly showed a crater floor containing a superheated lake 295 to 705 feet across. The lava is also 1,812 to 2,334 °F (1,279 °C), with the higher end of that range about as hot as lava on Earth seems to get.
