Question: Where is the continental limit of the continent where Gulch Island is found?

full_context: Document 1: 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 2: Gándara Island: Gándara Island is an island immediately southwest of Kopaitic Island in the Duroch Islands of Antarctica. The name appears on a Chilean government chart of 1959. It was presumably named for Comodoro Jorge Gándara, the leader of the 1954–55 Chilean Antarctic Expedition.
Document 3: 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 4: Chinstrap Point: Chinstrap Point is the southeast point of Vindication Island, South Sandwich Islands. This feature was named Rocky Point during a survey of the island from RRS "Discovery II" in 1930, but the name was changed to avoid duplication. The new name applied by the UK Antarctic Place-Names Committee in 1971 refers to the enormous colony of chinstrap penguins on the point.
Document 5: 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 6: Breaker Island: Breaker Island is a small rocky island lying in Arthur Harbour close south-west of Norsel Point, off the south-west coast of Anvers Island in the Palmer Archipelago of Antarctica. It was surveyed by the Falkland Islands Dependencies Survey (FIDS) in 1955 and named by the UK Antarctic Place-Names Committee (UK-APC) because the island causes breakers when the sea is rough.
Document 7: Gosling Islands: The Gosling Islands are a scattered group of islands and rocks lying close south and west of Meier Point, off the south coast of Coronation Island in the South Orkney Islands of Antarctica. They were first charted and named "Gestlingen" by Petter Sorlle in 1912–13. This was corrected to "Gjeslingene" (the goslings) on a later chart by Sorlle. The approved name is an anglicized form recommended by the UK Antarctic Place-Names Committee.
Document 8: 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 9: 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 10: Gulch Island (Antarctica): Gulch Island () is an island lying northwest of Small Island in the Christiania Islands, in the Palmer Archipelago, Antarctica. The island is shown on an Argentine government chart of 1952. Gulch Island was so named by the UK Antarctic Place-Names Committee in 1960 because the island is deeply indented.
Document 11: 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 12: 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 13: Outcast Islands: The Outcast Islands are two small islands, nearly apart, and a number of surrounding rocks lying southwest of Bonaparte Point, off the southwest coast of Anvers Island in the Palmer Archipelago of Antarctica. The Outcast Islands were named by the United Kingdom Antarctic Place-names Committee (UK-APC) following a survey in 1955 by the Falkland Islands Dependencies Survey (FIDS). The name arose because of their isolated position some distance from the other islands in the vicinity of Arthur Harbor.
Document 14: 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 15: Lacuna Island: Lacuna Island () is a small island lying east of Tula Point, the northern end of Renaud Island, in the Biscoe Islands, Antarctica. It was mapped from air photos obtained by Hunting Aerosurveys Ltd, 1956–57, and was so named by the UK Antarctic Place-Names Committee because the island lies in a lacuna (a gap) in the vertical air photos.
