COMPOSITE GAZETTEER OF ANTARCTICA

extending 25km SW from Lapeyrère Bay, Anvers Island, rising to 2570m at Mount Agamemnon and including also, from N to S, Mount Nestor, Mount Achilles and Mount Helen, was surveyed by FIDS from Arthur Harbour in 1955; photographed from the air by FIDASE, 1956-57, and so named in association with Trojan Range (q.v.) and other names from Homer's Iliad in this area (APC, 1958, p.4; BA chart 3566, 16.x.1959). Features in this range are named after individual Achæans.

Range of mountains rising to 1,370 m in the central part of Anvers Island in the Palmer Archipelago. It is bounded on the E by Iliad Glacier and Trojan Range and on the W by Marr Ice Piedmont, and extends NW from Mount Agamemnon for 6 mi, curving NE for a further 12 mi to Mount Nestor. Surveyed by the FIDS in 1955 and named by the UK-APC for the Achaeans, one of the opposing forces of the Trojan War in Homer's Iliad.

The basin is an approximately triangular shaped basin of Taynaya Bay in the Vestfold Hills. It is 1 km long and 0.8km wide. The maximum known depth of the basin is 32 m although deeper spots may occur. The water of the basin is stratified, being near seawater salinity at the surface and increasing to circa 70 gL-1 at 30 m. Stratification begins at a depth of 10 m. The basin is one of the approximately 7 stratified marine basins that occur in the Vestfold Hills. Such basins are rare and these are probably the only known examples from Antarctica. The biology of Burke Basin is likely to be similar to the rest of Taynaya Bay and the ocean in the upper water, but like meromictic lakes in the lower water. The anoxic water probably supports dense populations of sulphate reducing bacteria beneath a layer of photosynthetic sulphur bacteria.
