Question: Since what year has tourism been ongoing to the continent of Ginger Islands?

full_context: Document 1: Antarctica: Small-scale "expedition tourism" has existed since 1957 and is currently subject to Antarctic Treaty and Environmental Protocol provisions, but in effect self-regulated by the International Association of Antarctica Tour Operators (IAATO). Not all vessels associated with Antarctic tourism are members of IAATO, but IAATO members account for 95% of the tourist activity. Travel is largely by small or medium ship, focusing on specific scenic locations with accessible concentrations of iconic wildlife. A total of 37,506 tourists visited during the 2006–07 Austral summer with nearly all of them coming from commercial ships. The number was predicted to increase to over 80,000 by 2010.
Document 2: 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 3: 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 4: Antarctica: A census of sea life carried out during the International Polar Year and which involved some 500 researchers was released in 2010. The research is part of the global Census of Marine Life (CoML) and has disclosed some remarkable findings. More than 235 marine organisms live in both polar regions, having bridged the gap of 12,000 km (7,456 mi). Large animals such as some cetaceans and birds make the round trip annually. More surprising are small forms of life such as mudworms, sea cucumbers and free-swimming snails found in both polar oceans. Various factors may aid in their distribution – fairly uniform temperatures of the deep ocean at the poles and the equator which differ by no more than 5 °C, and the major current systems or marine conveyor belt which transport eggs and larval stages.
Document 5: 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 6: 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 7: Cape James: Cape James is a cape which forms the southern tip of Smith Island in the South Shetland Islands, Antarctica. The name appears on a chart based upon the 1828–31 British naval expedition under Captain Henry Foster, and is now well established in international usage.
Document 8: 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 9: Terra Firma Islands: The Terra Firma Islands are a small group of islands lying north of Cape Berteaux, off the west coast of Graham Land in West Antarctica. Roughly surveyed by the British Graham Land Expedition (BGLE) in 1936. The name "Terra Firma Island" was applied to the largest island (Alamode Island, q.v.), because a BGLE depot-laying party camped there following the break-up of sea ice, but the name Terra Firma Islands was later applied to the whole group. They include Dumbbell Island.
Document 10: Ginger Islands: The Ginger Islands are a group of islands lying west of Cape Alexandra, off the southern end of Adelaide Island, Antarctica. The largest of the islands appears reddish when free of snow. They were surveyed by the Royal Navy's hydrographic survey unit in 1962-63 and named by the United Kingdom Antarctic Place-Names Committee (UK-APC) for Kenneth Ginger, Civil Hydrographic Officer responsible for British Admiralty charts of the Antarctic for several years beginning in 1958.
Document 11: 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 12: 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 13: Henkes Islands: The Henkes Islands are a group of small islands and rocks in extent, lying southwest of Avian Island, close off the southern extremity of Adelaide Island, Antarctica. The islands were discovered by the French Antarctic Expedition, 1908–10, under Jean-Baptiste Charcot, and named by him for one of the Dutch directors of the Magellan Whaling Company at Punta Arenas. Charcot applied the name to the scattered rocks and islands between Cape Adriasola and Cape Alexandra, and the name was restricted to the group described by the UK Antarctic Place-Names Committee (UKAPC) following definitive mapping by the British Antarctic Survey (BAS) in 1961 and the British Royal Navy Hydrographic Survey (BRNHS) in 1963. All of the islands in the group were named by UKAPC.
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: Saint Helena: The tourist industry is heavily based on the promotion of Napoleon's imprisonment. A golf course also exists and the possibility for sportfishing tourism is great. Three hotels operate on the island but the arrival of tourists is directly linked to the arrival and departure schedule of the RMS St Helena. Some 3,200 short-term visitors arrived on the island in 2013.
