Vestfold Hills
Template:Short description The Vestfold Hills are rounded, rocky, coastal hills, Script error: No such module "convert". in extent,[1][2] on the north side of Sorsdal Glacier on the Ingrid Christensen Coast of Princess Elizabeth Land, Antarctica. The hills are subdivided by three west-trending peninsulas bounded by narrow fjords. Most of the hills range between Script error: No such module "convert". in height, with the highest summit reaching nearly Script error: No such module "convert"..
Geography
The Vestfold Hills are largely snow- and ice-free and are thus classified as an Antarctic oasis. They contain a great variety of lake systems with over 300 lakes and ponds[3] including what is possibly the largest concentration of meromictic (stratified) lakes in the world.[4] This region contains 37 permanently stratified water bodies,[5] including six marine basins and seven seasonally isolated marine basins (SIMBs). These stratified basins also have great variety. They range in salinity from 4 g L−1 to 235 g L−1, in temperature from Script error: No such module "convert"., in depth from Script error: No such module "convert"., in area from Script error: No such module "convert". and surface level from Script error: No such module "convert". below to Script error: No such module "convert". above sea level.[4] The region contains a large lake, Lake Burton, as well as the smaller Krok Lake and Camp Lake.
History and naming
The Vestfold Hills were discovered, and a landing was made in the northern portion, on February 20, 1935, by Captain Klarius Mikkelsen together with his wife and seven crew members (including the ship's dentist, Lief Sørsdal) of the Norwegian whaling ship "Thorshavn" sent out by Lars Christensen. Caroline Mikkelsen, thereby became the first woman to set foot on the Antarctic continent.Script error: No such module "Unsubst".
The Vestfold Hills are named after Vestfold, a county in Norway where Sandefjord, headquarters of the whaling industry, was located. This hill area and its off-lying islands were mapped from air photos taken by the Lars Christensen Expedition (1936–37). Further brief landings were made by Lincoln Ellsworth and several claims were made by Hubert Wilkins in 1939. The area was photographed from the air by USN Operation Highjump (1946–47). Landings were made and exploration carried out in 1954 and 1955 by ANARE (Australian National Antarctic Research Expeditions) led by Phillip Law. Davis Station was established by ANARE in January 1957.[6]
