In 1830, the
whaling company
Samuel Enderby & Sons appointed Biscoe
master of the
brig Tula and leader of an expedition to find new sealing grounds in the
Southern Ocean. Accompanied by the
cutter Lively, the
Tula left London and by December had reached the
South Shetland Islands. The expedition then sailed further south, crossing the
Antarctic Circle on 22 January 1831, before turning east at
60°S. A month later, on 24 February 1831, the expedition sighted bare mountain tops through the ocean ice. Biscoe correctly surmised that they were part of a continent and named the area
Enderby Land in honour of his patrons. On 28 February, a headland was spotted, which Biscoe named
Cape Ann; the mountain atop the headland would later be named
Mount Biscoe. Biscoe kept the expedition in the area while he began to chart the coastline, but after a month his and his crews' health were deteriorating. The expedition sailed toward Australia, reaching
Hobart, Tasmania in May, but not before two crew members had died from
scurvy. The expedition wintered in Hobart before heading back toward the Antarctic. On 15 February 1832,
Adelaide Island was discovered and two days later the
Biscoe Islands. A further four days later, on 21 February, more extensive coastline was spotted. Surmising again that he had encountered a continent, Biscoe named the area
"Graham Land", after
First Lord of the Admiralty Sir
James Graham. Biscoe landed on
Anvers Island and claimed to have sighted the mainland of the Antarctic continent. Biscoe again began charting the new coastline the expedition had found and by the end of April 1832 he had become the third man (after
James Cook and
Fabian von Bellingshausen) to
circumnavigate the Antarctic continent. On the journey home, in July, the
Lively was wrecked at the
Falkland Islands. The expedition nonetheless returned to London safely by the beginning of 1833. In 1833, Biscoe was again commissioned by Samuel Enderby & Sons to make another voyage of exploration. However, he resigned from the effort, probably because of his health. He instead engaged in the West Indies trade in a much warmer climate. He next took part in sailing ventures in Australian waters. John Biscoe died at sea in 1843 while on a voyage to bring his family from
Tasmania back to England. He was 49 years old. ==Memorials==
