Question: What is the size of the continent Marian Cove is located in square miles?

full_context: Document 1: Killermet Cove: Killermet Cove () is the southernmost of two coves indenting the west side of Bryde Island, off the west coast of Graham Land, Antarctica. The cove appears on an Argentine government chart of 1950. It was so named by the UK Antarctic Place-Names Committee in 1960 because three members of the Falkland Islands Dependencies Survey were chased into this cove in their dinghies by six killer whales while circumnavigating Bryde Island in May 1957. The three members' names were Evans, Hobbs and O'Neill.
Document 2: Barton Peninsula: Barton Peninsula is a small peninsula separating Marian Cove and Potter Cove at the southwest end of King George Island, in the South Shetland Islands of Antarctica. It was named by the UK Antarctic Place-Names Committee in 1963 for Colin Barton, Falkland Islands Dependencies Survey geologist who worked in this part of King George Island, 1959-61.
Document 3: 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 4: Islands Point: Islands Point () is a high rock point separating Berg Bay and Relay Bay, lying along the west shore of Robertson Bay in Victoria Land, Antarctica. The headland was charted by the northern party of the British Antarctic Expedition, 1910–13, under Captain Robert Falcon Scott, and was probably named with reference to the small island (Sphinx Rock) which lies just north of the point. The headland lies situated on the Pennell Coast, a portion of Antarctica lying between Cape Williams and Cape Adare.
Document 5: Antarctic Plate: The Antarctic Plate is a tectonic plate containing the continent of Antarctica, the Kerguelen Plateau and extending outward under the surrounding oceans. After breakup from Gondwana (the southern part of the supercontinent Pangea), the Antarctic plate began moving the continent of Antarctica south to its present isolated location causing the continent to develop a much colder climate. The Antarctic Plate is bounded almost entirely by extensional mid-ocean ridge systems. The adjoining plates are the Nazca Plate, the South American Plate, the African Plate, the Somali Plate, the Indo-Australian Plate, the Pacific Plate, and, across a transform boundary, the Scotia Plate.
Document 6: 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 7: Baba Tonka Cove: Baba Tonka Cove (, ‘Zaliv Baba Tonka’ \'za-liv 'ba-ba 'ton-ka\) is the 1.1 km wide cove indenting for 750 m the north coast of Byers Peninsula between Villard Point and Varadero Point on Livingston Island in the South Shetland Islands, Antarctica. The area was visited by early 19th century sealers.
Document 8: Gibbs Point: Gibbs Point, a rock point on the Antarctic Peninsula, the most northern area of the continent of Antarctica, was named for African American Antarctic explorer, George W. Gibbs, Jr. on September 2, 2009. On that date, the Advisory Committee on Antarctic Names (U.S. Board on Geographic Names) confirmed the place name in Antarctica for Gibbs as the first black explorer to set foot on the continent. Gibbs Point is a rock point forming the northwest entrance to Gaul Cove, on the northeast of Horseshoe Island, Marguerite Bay, Antarctic Peninsula.
Document 9: Hydra Cove: Hydra Cove is a small cove indenting for 200 m the northwest coast of Varna Peninsula, Livingston Island in the South Shetland Islands, Antarctica and entered north of Gargoyle Bastion.
Document 10: 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 11: 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 12: Southern Ocean: The Southern Ocean, geologically the youngest of the oceans, was formed when Antarctica and South America moved apart, opening the Drake Passage, roughly 30 million years ago. The separation of the continents allowed the formation of the Antarctic Circumpolar Current.
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: 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.
Document 15: Marian Cove: Marian Cove () is a cove indenting the southwest part of King George Island between Collins Harbour and Potter Cove, in the South Shetland Islands, Antarctica. The name was used by Scottish geologist David Ferguson in a 1921 report based upon his investigations of King George Island in 1913–14, but may reflect an earlier naming.
