Belgica Glacier is a glacier 8 nautical miles (15 km) long, flowing into Trooz Glacier to the east of Lancaster Hill on Kyiv Peninsula, on the west coast of Graham Land. It was first charted by the British Graham Land Expedition under John Rymill, 1934–37, and named by the UK Antarctic Place-Names Committee in 1959 after the RV Belgica, the ship of the Belgian Antarctic Expedition under Gerlache which explored this area in 1897–99.
Johnston Passage is a channel in Antarctica, running north–south and separating the Amiot Islands from the southwestern part of Adelaide Island. It was named by the UK Antarctic Place-Names Committee for Captain William Johnston, from 1956 to 1962 Master of RRS John Biscoe, the ship which assisted the Royal Navy Hydrographic Survey Unit in charting this area in 1963.
Phelps Rock is an insular rock rising 10 m above sea level southwest of Hugo Island, in the west approaches to French Passage, Wilhelm Archipelago. The rock was charted by a Royal Navy Hydrographic Survey Unit from HMS Protector, 1966–67. Named by United Kingdom Antarctic Place-Names Committee (UK-APC) after Captain Edmund M.S. Phelps, First Officer in John Biscoe, 1966-72, who assisted with the hydrographic survey of the area, 1965–67.
Forsters Passage is a body of water between Bristol Island and Southern Thule in the South Sandwich Islands. In 1775, a British expedition under James Cook gave the name "Forster's Bay", after John R. Forster, a naturalist with the expedition, to what appeared to be a bay in essentially this position. The "bay" was determined to be a strait by a Russian expedition under Fabian Gottlieb von Bellingshausen in 1820.
Mudge Passage is a marine passage running east–west from the vicinity of Prospect Point, Graham Coast, between Beer Island and Dodman Island to the north and Saffery Islands and Trump Islands to the south, to the vicinity of Extension Reef. The passage was navigated and charted by Captain C.R. Elliott in RRS John Biscoe in January 1979. Named by the United Kingdom Antarctic Place-Names Committee (UK-APC) in association with Harrison Passage and Maskelyne Passage to the northeast, after Thomas Mudge (1715–94), English horologist who made substantial improvements to marine chronometers.
Hamblin Glacier is a glacier flowing to the southeast side of Widmark Ice Piedmont, in Graham Land, Antarctica. It was photographed by Hunting Aerosurveys Ltd in 1955–57, and mapped from these photos by the Falkland Islands Dependencies Survey. It was named by the UK Antarctic Place-Names Committee in 1959 for Theodore Hamblin (1873–1952), an English optician who in the 1930s helped in the evolution of the first satisfactory snow goggle design.
Lord Bank is a submarine bank in the Bellingshausen Sea with a least depth of 18 metres (60 ft) lying west-southwest of the entrance to Quest Channel, Adelaide Island, Antarctica.

It was named by the UK Antarctic Place-Names Committee in 1959 for John Harrison, an English horologist who first definitely solved the problem of determining longitude at sea.
Heap Island is an island off the southeast coast of Renaud Island in the Biscoe Islands of the Graham Coast of Antarctica, between Jurva Point and Bates Island. In association with the names of sea-ice specialists grouped in this area, it was named by the UK Antarctic Place-Names Committee (UK-APC) in 1985 after John A. Heap, a sea-ice specialist with the Falkland Islands Dependencies Survey (FIDS), 1955–62, who worked in the Antarctic with FIDS, 1955–56, with the Commonwealth Trans-Antarctic Expedition, 1956–57, and with the United States Antarctic Research Program, 1962–63. He was later head of the Polar Regions Section at the Foreign and Commonwealth Office, and a member of the UK-APC from 1976.

Charted in 1944 by the Falkland Islands Dependencies Survey (FIDS), and so named by them because a survey party was nearly overwhelmed there by an avalanche.
