Question: Where is the continental limit for the continent where Megaw Island is located?

full_context: Document 1: Antarctica: Emilio Marcos Palma was the first person born south of the 60th parallel south (the continental limit according to the Antarctic Treaty), as well as the first one born on the Antarctic mainland, in 1978 at Base Esperanza, on the tip of the Antarctic Peninsula; his parents were sent there along with seven other families by the Argentine government to determine if the continent was suitable for family life. In 1984, Juan Pablo Camacho was born at the Frei Montalva Station, becoming the first Chilean born in Antarctica. Several bases are now home to families with children attending schools at the station. As of 2009, eleven children were born in Antarctica (south of the 60th parallel south): eight at the Argentine Esperanza Base and three at the Chilean Frei Montalva Station.
Document 2: Haswell Island: Haswell Island is the largest of the Haswell Islands, lying off the coast of Antarctica, about north of Mabus Point in Queen Mary Land. It was discovered by the Western Base Party of the Australasian Antarctic Expedition, 1911–14, under Mawson, and named by him for Professor William A. Haswell, a zoologist at Sydney University and a member of the expedition's Advisory Committee.
Document 3: Fourier Island: Fourier Island is a small rocky island off the coast and east-northeast of Cape Mousse, Antarctica. It was charted in 1951 by the French Antarctic Expedition and named by them for Jean-Baptiste Fourier, the French geometrician.
Document 4: Antarctica: The first semi-permanent inhabitants of regions near Antarctica (areas situated south of the Antarctic Convergence) were British and American sealers who used to spend a year or more on South Georgia, from 1786 onward. During the whaling era, which lasted until 1966, the population of that island varied from over 1,000 in the summer (over 2,000 in some years) to some 200 in the winter. Most of the whalers were Norwegian, with an increasing proportion of Britons. The settlements included Grytviken, Leith Harbour, King Edward Point, Stromness, Husvik, Prince Olav Harbour, Ocean Harbour and Godthul. Managers and other senior officers of the whaling stations often lived together with their families. Among them was the founder of Grytviken, Captain Carl Anton Larsen, a prominent Norwegian whaler and explorer who, along with his family, adopted British citizenship in 1910.
Document 5: Fowler Islands: The Fowler Islands () are a group of small islands lying between the Bernal Islands and the Bragg Islands in Crystal Sound, off the coast of Antarctica. They were mapped from air photos obtained by the Ronne Antarctic Research Expedition (1947–48) and the Falkland Islands and Dependencies Aerial Survey Expedition (1956–57), and from surveys by the Falkland Islands Dependencies Survey (1958–59). They were named by the UK Antarctic Place-Names Committee for Sir Ralph H. Fowler (1889–1944), an English physicist, joint author with J.D. Bernal of a classic paper in 1933 on the structure of ice which suggested the location of the hydrogen atoms now known as the ice rules.
Document 6: Heap Island: 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.
Document 7: Megaw Island: Megaw Island () is the easternmost of the Bennett Islands in Hanusse Bay, Antarctica. It was mapped from air photos taken by the Ronne Antarctic Research Expedition (1947–48) and the Falkland Islands and Dependencies Aerial Survey Expedition (1956–57). The island was named by the UK Antarctic Place-Names Committee for Irish physicist Helen Megaw, who in 1934 made accurate measurements of the cell dimensions of ice.
Document 8: Antarctica: New claims on Antarctica have been suspended since 1959 although Norway in 2015 formally defined Queen Maud Land as including the unclaimed area between it and the South Pole. Antarctica's status is regulated by the 1959 Antarctic Treaty and other related agreements, collectively called the Antarctic Treaty System. Antarctica is defined as all land and ice shelves south of 60° S for the purposes of the Treaty System. The treaty was signed by twelve countries including the Soviet Union (and later Russia), the United Kingdom, Argentina, Chile, Australia, and the United States. It set aside Antarctica as a scientific preserve, established freedom of scientific investigation and environmental protection, and banned military activity on Antarctica. This was the first arms control agreement established during the Cold War.
Document 9: Antarctica: Several governments maintain permanent manned research stations on the continent. The number of people conducting and supporting scientific research and other work on the continent and its nearby islands varies from about 1,000 in winter to about 5,000 in the summer, giving it a population density between 70 and 350 inhabitants per million square kilometres (180 and 900 per million square miles) at these times. Many of the stations are staffed year-round, the winter-over personnel typically arriving from their home countries for a one-year assignment. An Orthodox church—Trinity Church, opened in 2004 at the Russian Bellingshausen Station—is manned year-round by one or two priests, who are similarly rotated every year.
Document 10: Molecule Island: Molecule Island is the easternmost of the Bragg Islands, lying in Crystal Sound north of Cape Rey, Graham Land, Antarctica. It was mapped from surveys by the Falkland Islands Dependencies Survey in 1958–59. The name arose from association with Atom Rock in the same group.
Document 11: Chilean Antarctic Territory: The Chilean Antarctic Territory or Chilean Antarctica (Spanish: "Territorio Chileno Antártico", "Antártica Chilena") is the territory in Antarctica claimed by Chile. The Chilean Antarctic Territory ranges from 53° West to 90° West and from the South Pole to the 60° South parallel, partially overlapping the Argentine and British Antarctic claims. It is administered by the Cabo de Hornos municipality in the South American mainland.
Document 12: Emilio Palma: Emilio Marcos Palma (born 7 January 1978) is an Argentine man known for being the first documented person born on the continent of Antarctica.
Document 13: Chileans: Though the majority of Chileans reside in Chile, significant communities have been established in multiple countries, most noticeably Argentina, United States, Australia and Canada and countries of the European Union. Although small in number, Chilean people also make up a substantial part of the permanent population of Antarctica and the Falkland Islands (see: Chileans in the Falkland Islands).
Document 14: Antarctic Peninsula: The Antarctic Peninsula, known as O'Higgins Land in Chile, Tierra de San Martin in Argentina, and originally known as the Palmer Peninsula in the US and as Graham Land in Great Britain, is the northernmost part of the mainland of Antarctica, located at the base of the Southern Hemisphere.
Document 15: Hansen Rocks: The Hansen Rocks are a group of five small islands lying just north of Holme Bay and the coast of Mac. Robertson Land, Antarctica, about northeast of the Sawert Rocks and Nella Rock, and about northwest of the Canopus Rocks. They were plotted from Australian National Antarctic Research Expeditions (ANARE) air photographs, and were named by the Antarctic Names Committee of Australia for Captain B.T. Hansen, master of the "Nella Dan" for ANARE relief voyages in 1968, 1969, 1970 and 1972.
