Base Orcadas is an Argentine scientific station in Antarctica, and the oldest of the stations in Antarctica still in operation. It is located on Laurie Island, one of the South Orkney Islands ((スペイン語:Islas Orcadas del Sur)), at above sea level and from the coastline. Established by the Scottish National Antarctic Expedition in 1903 and transferred to the Argentine government in 1904, the base has been permanently populated since, being one of six Argentine permanent bases in Argentina's claim to Antarctica, and the first permanently inhabited base in Antarctica. The nearest port is the Argentine city of Ushuaia, which is away. The base has 11 buildings and four main topics of research: continental glaciology, seismology, sea-ice-zone glaciology (since 1985) and meteorological observations (since 1903). Orcadas was the only station on the islands for 40 years until the British established a small summer base, Cape Geddes Station in Laurie Island in 1946, replaced by Signy Research Station in Signy Island in 1947. It also had the first radiotelegraph in the continent in 1927. The 11 buildings of the station house up to 45 people during the summer, and an average of 14 during winter. ==History== In 1903 Dr William S. Bruce's Scottish National Antarctic Expedition established ''Omond House'', a meteorological station on Laurie Island. During the expedition, however, the crew became stuck in the ice and, unable to sail off, were trapped in the station for the winter. Bruce left the station in December of that year for Buenos Aires to fix the ship and obtain supplies, leaving meteorologist Robert C. Mossman in charge of the base to continue the observations. Bruce offered to the Government of President Julio Argentino Roca the transfer of the station and instruments for the sum of 5.000 pesos, on the condition that the government committed itself to the continuation of the scientific mission. He also offered to transport in his ship the appointed personnel back to the station. Bruce had informed the British officer William Haggard of his intentions in December 1903. On 29 December, Haggard sent a note to the Argentine Foreign Minister, Jose Terry, ratifying the terms of Bruce proposition.〔 Roca submitted the matter to the ''Oficina Meteorologica Nacional'' (National Office of Meteorology) who advised to accept the offer. On January 2, 1904, the installations were accepted through a presidential decree. The ''Scotia'' sailed back for Laurie Island on 14 January 1904 carrying on board Luciano H. Valette, from the Office of Zoology of the Ministry of Agriculture, Edgard C. Szmula, employee of the National Meteorological Office, and Hugo Acuña, from the Ministry of Livestock, who was also designated Postal Chief of the Orkney Islands by the Director General of the National Postal and Telegraphs Office, Manuel Garcia Fernandez. Mossman was left in charge of the expedition, along with William Smith as cook. In 1906, Argentina communicated to the international community the establishment of a permanent base on the South Orkney Islands. On August 26, Haggard sent a letter to Foreign Minister Manuel Montes de Oca reminding him that South Orkneys Islands were British. The British position was that Argentine personnel was granted permission only for the period of one year. Argentine government ignored the note, "considering it out of time".〔 On March 30, 1927, naval non-commissioned officer Emilio Baldoni established the first radio telegraph link with Ushuaia. Up to that point, the Orcadas Base remained isolated from the rest of the world until the yearly relief arrived. The radio station (coded LRT in Argentina) allowed for a permanent communication link. The station depended on the Ministry of Agriculture until Argentine Navy relieved the crew with navy personnel on March 3, 1951. Formal transfer occurred on December 23, 1952, when by presidential decree the base was put under the Service of Maritime Hydrography as ''Destacamento Naval Orcadas''. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Orcadas Base」の詳細全文を読む スポンサード リンク
