Question: What is the size of the continent the Luke Glacier is located?

full_context: Document 1: Lange Glacier: Lange Glacier () is a glacier flowing into the west side of Admiralty Bay close south of Admiralen Peak, King George Island, in the South Shetland Islands, Antarctica. It was charted by the French Antarctic Expedition, 1908–10, under Jean-Baptiste Charcot, and was named by the UK Antarctic Place-Names Committee in 1960 for Alexander Lange (1860–1922), a Norwegian pioneer of modern steam whaling in the South Shetland Islands in 1905–6, and commander of the "Admiralen".
Document 2: George Glacier: George Glacier is a valley glacier in the western part of the Anare Mountains of Victoria Land, Antarctica. The glacier rises east of Mount Burch and flows northwest past Mount Kelly to Lillie Glacier Tongue on the coast. This geographical feature was first mapped by the United States Geological Survey from surveys and U.S. Navy air photos, 1960–1965, and was named by the Advisory Committee on Antarctic Names for Robert Y. George, a zoologist at McMurdo Station, Hut Point Peninsula, Ross Island, 1967–1968. The glacier is situated on the Pennell Coast, a portion of Antarctica lying between Cape Williams and Cape Adare.
Document 3: Leonardo Glacier: Leonardo Glacier is a glacier flowing into Wilhelmina Bay between Sadler Point and Café Point, on the west coast of Graham Land, Antarctica. It was charted by the Belgian Antarctic Expedition under Gerlache, 1897–99, and was named by the UK Antarctic Place-Names Committee in 1960 for Leonardo da Vinci, artist, musician, architect and the first aeronautical scientist.
Document 4: Lacroix Glacier: Lacroix Glacier () is a glacier between Suess Glacier and Matterhorn Glacier, which flows southeast into Taylor Valley in Victoria Land, Antarctica. It was mapped by the British Antarctic Expedition, 1910–13, under Robert Falcon Scott, and named after Alfred Lacroix, as was Mount Lacroix.
Document 5: Antarctica: About 98% of Antarctica is covered by the Antarctic ice sheet, a sheet of ice averaging at least 1.6 km (1.0 mi) thick. The continent has about 90% of the world's ice (and thereby about 70% of the world's fresh water). If all of this ice were melted, sea levels would rise about 60 m (200 ft). In most of the interior of the continent, precipitation is very low, down to 20 mm (0.8 in) per year; in a few "blue ice" areas precipitation is lower than mass loss by sublimation and so the local mass balance is negative. In the dry valleys, the same effect occurs over a rock base, leading to a desiccated landscape.
Document 6: Lind Glacier: Lind Glacier () is a glacier flowing west from Alencar Peak into the southern part of Collins Bay, on the west coast of Kiev Peninsula in Graham Land, Antarctica. It was first charted by the Fourth French Antarctic Expedition under Jean-Baptiste Charcot, 1908–10, and was named by the UK Antarctic Place-Names Committee in 1959 for James Lind, the Scottish "founder of modern naval hygiene," who was the first to publish a convincing account of experimental work establishing the dietary cause and cure of scurvy, in 1755.
Document 7: Antarctica: Antarctica (US English i/æntˈɑːrktɪkə/, UK English /ænˈtɑːktɪkə/ or /ænˈtɑːtɪkə/ or /ænˈɑːtɪkə/)[Note 1] is Earth's southernmost continent, containing the geographic South Pole. It is situated in the Antarctic region of the Southern Hemisphere, almost entirely south of the Antarctic Circle, and is surrounded by the Southern Ocean. At 14,000,000 square kilometres (5,400,000 square miles), it is the fifth-largest continent in area after Asia, Africa, North America, and South America. For comparison, Antarctica is nearly twice the size of Australia. About 98% of Antarctica is covered by ice that averages 1.9 km (1.2 mi; 6,200 ft) in thickness, which extends to all but the northernmost reaches of the Antarctic Peninsula.
Document 8: Ball Glacier (Victoria Land): Ball Glacier is a glacier long with the head located between Mount Lister and Mount Hooker on the east side of the Royal Society Range. The glacier flows northeast between Craw Ridge and Tasman Ridge into Blue Glacier. It was named by the New Zealand Geographic Board after Gary Ball, a New Zealand mountaineer who climbed Mount Lister with an Italian field party, 1976–77, and camped on this glacier; he was field assistant with R.H. Findlay’s New Zealand Antarctic Research Program party to this area, 1980–81.
Document 9: Luke Glacier: Luke Glacier () is a glacier at least long, flowing northwest into the head of Leroux Bay on the west coast of Graham Land, Antarctica. It is surmounted by Mount Chevreux on the south, Mount Perchot on the southwest and Mount Radotina on the northeast. The glacier was first sighted and roughly surveyed in 1909 by the Fourth French Antarctic Expedition. It was resurveyed in 1935–36 by the British Graham Land Expedition and later named for George Lawson Johnston, 1st Baron Luke of Pavenham, Chairman of Bovril Ltd, who contributed toward the cost of the expedition.
Document 10: Antarctica: Antarctica is colder than the Arctic for three reasons. First, much of the continent is more than 3,000 m (9,800 ft) above sea level, and temperature decreases with elevation in the troposphere. Second, the Arctic Ocean covers the north polar zone: the ocean's relative warmth is transferred through the icepack and prevents temperatures in the Arctic regions from reaching the extremes typical of the land surface of Antarctica. Third, the Earth is at aphelion in July (i.e., the Earth is farthest from the Sun in the Antarctic winter), and the Earth is at perihelion in January (i.e., the Earth is closest to the Sun in the Antarctic summer). The orbital distance contributes to a colder Antarctic winter (and a warmer Antarctic summer) but the first two effects have more impact.
Document 11: Flask Glacier: Flask Glacier (), is a gently-sloping glacier, long, flowing east from Bruce Plateau to enter Scar Inlet between Daggoo Peak and Spouter Peak in Graham Land, Antarctica. The lower reaches of this glacier were surveyed and photographed by the Falklands Islands Dependencies Survey (FIDS) in 1947. The entire glacier was photographed by the Falkland Islands and Dependencies Aerial Survey Expedition in 1955–56, and mapped by the FIDS in 1957. It was named by the UK Antarctic Place-names Committee after the third mate on the "Pequod" in Herman Melville's "Moby-Dick; or, The White Whale".
Document 12: Antarctica: Positioned asymmetrically around the South Pole and largely south of the Antarctic Circle, Antarctica is the southernmost continent and is surrounded by the Southern Ocean; alternatively, it may be considered to be surrounded by the southern Pacific, Atlantic, and Indian Oceans, or by the southern waters of the World Ocean. It covers more than 14,000,000 km2 (5,400,000 sq mi), making it the fifth-largest continent, about 1.3 times as large as Europe. The coastline measures 17,968 km (11,165 mi) and is mostly characterized by ice formations, as the following table shows:
Document 13: Wilkes Land: Wilkes Land is a large district of land in eastern Antarctica, formally claimed by Australia as part of the Australian Antarctic Territory, though the validity of this claim has been placed for the period of the operation of the Antarctic Treaty, to which Australia is a signatory. It fronts on the southern Indian Ocean between Queen Mary Coast and Adelie Land, extending from Cape Hordern in 100°31' E to Pourquoi Pas Point, in 136°11' E. The region extends as a sector about 2600 km towards the South Pole, with an estimated land area of 2,600,000 km², mostly glaciated. It is further subdivided in the following coastal areas which can also be thought of as sectors extending to the South Pole:
Document 14: Ice sheet: The Antarctic ice sheet is the largest single mass of ice on Earth. It covers an area of almost 14 million km and contains 30 million km of ice. Around 90% of the Earth's ice mass is in Antarctica, which, if melted, would cause sea levels to rise by 58 meters. The continent - wide average surface temperature trend of Antarctica is positive and significant at > 0.05 ° C / decade since 1957.
Document 15: Antarctica: Due to its location at the South Pole, Antarctica receives relatively little solar radiation. This means that it is a very cold continent where water is mostly in the form of ice. Precipitation is low (most of Antarctica is a desert) and almost always in the form of snow, which accumulates and forms a giant ice sheet which covers the land. Parts of this ice sheet form moving glaciers known as ice streams, which flow towards the edges of the continent. Next to the continental shore are many ice shelves. These are floating extensions of outflowing glaciers from the continental ice mass. Offshore, temperatures are also low enough that ice is formed from seawater through most of the year. It is important to understand the various types of Antarctic ice to understand possible effects on sea levels and the implications of global cooling.
