Question: What latitude is defined as the border of the continent on which Killermet Cove is located?

full_context: Document 1: Leith Cove: Leith Cove () is a cove in the northeast part of Paradise Harbor, along the west coast of Graham Land, Antarctica. It was probably named by whalers operating in this vicinity, as Leith, Scotland, was the home of Salvesen and Company, whalers.
Document 2: 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 3: 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 4: Cora Cove: Cora Cove is the 750 m wide cove in the northwest part of Blythe Bay indenting for 590 m the southeast coast of Desolation Island off Livingston Island in the South Shetland Islands, Antarctica. The cove was used by early 19th century sealers operating from Blythe Bay.
Document 5: Australian Antarctic Data Centre: Article III.1.c of the Antarctic Treaty states that "to the greatest extent feasible and practicable" ... "scientific observations and results from Antarctica shall be exchanged and made freely available"
Document 6: Antarctica: Although coal, hydrocarbons, iron ore, platinum, copper, chromium, nickel, gold and other minerals have been found, they have not been in large enough quantities to exploit. The 1991 Protocol on Environmental Protection to the Antarctic Treaty also restricts a struggle for resources. In 1998, a compromise agreement was reached to place an indefinite ban on mining, to be reviewed in 2048, further limiting economic development and exploitation. The primary economic activity is the capture and offshore trading of fish. Antarctic fisheries in 2000–01 reported landing 112,934 tonnes.
Document 7: National Antarctic Program: Till date 48 countries have signed the Antarctic Treaty which was drafted and negotiated back in 1959. Out of these, only 28 countries have the Consultative status i.e. these Parties have the right to participate in Antarctic Treaty Consultative Meetings (ATCM) and are accordingly known as Consultative Parties and their presence in Antarctica is shown by carrying substantial research there.
Document 8: Ivaylo Cove: Ivaylo Cove (, ‘Ivaylov Zaliv’ \i-'vay-lov 'za-liv\) is the 500 m wide cove indenting for 900 m the east coast of Snow Island in the South Shetland Islands, Antarctica. Bounded by the two arms of the small Hall Peninsula, the south one extended by a chain of rocks.
Document 9: 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 10: 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 11: 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 12: Rodman Cove: Rodman Cove is a cove south of Cape Lindsey on the west coast of Elephant Island, in the South Shetland Islands of Antarctica. It was named for Benjamin Rodman of New Bedford, Massachusetts, owner of whaling ships operating from that port in the 1820s and 1830s. The name was suggested by American geographer Lawrence Martin and has appeared in descriptions and charts of Elephant Island since about 1943.
Document 13: Antarctica: The Protocol on Environmental Protection to the Antarctic Treaty (also known as the Environmental Protocol or Madrid Protocol) came into force in 1998, and is the main instrument concerned with conservation and management of biodiversity in Antarctica. The Antarctic Treaty Consultative Meeting is advised on environmental and conservation issues in Antarctica by the Committee for Environmental Protection. A major concern within this committee is the risk to Antarctica from unintentional introduction of non-native species from outside the region.
Document 14: Whalers Bay (South Shetland Islands): Whalers Bay is a small bay entered between Fildes Point and Penfold Point at the east side of Port Foster, Deception Island, in the South Shetland Islands of Antarctica. The bay was so named by the French Antarctic Expedition, 1908-10, under Charcot, because of its use at that time by whalers.
Document 15: Antarctica: In 1983, the Antarctic Treaty Parties began negotiations on a convention to regulate mining in Antarctica. A coalition of international organizations launched a public pressure campaign to prevent any minerals development in the region, led largely by Greenpeace International, which established its own scientific station—World Park Base—in the Ross Sea region and conducted annual expeditions to document environmental effects of humans on Antarctica. In 1988, the Convention on the Regulation of Antarctic Mineral Resources (CRAMRA) was adopted. The following year, however, Australia and France announced that they would not ratify the convention, rendering it dead for all intents and purposes. They proposed instead that a comprehensive regime to protect the Antarctic environment be negotiated in its place. The Protocol on Environmental Protection to the Antarctic Treaty (the "Madrid Protocol") was negotiated as other countries followed suit and on 14 January 1998 it entered into force. The Madrid Protocol bans all mining in Antarctica, designating Antarctica a "natural reserve devoted to peace and science".
