Gun Island is one of the larger islands in the Pelsaert Group of the Houtman Abrolhos, in the Indian Ocean off the west coast of Australia. It is nominally located at ,〔''Gazetteer of Australia'' (1996). Belconnen, ACT: Australian Surveying and Land Information Group.〕 about 4 km north and east of Half Moon Reef and is a flat limestone outcrop of about by in size. The island is part of the Houtman Abrolhos Important Bird Area, identified as such by BirdLife International because of its importance for supporting large numbers of breeding seabirds. ==History== Between June 1727 and March 1728, crew of the Dutch VOC ship ''Zeewyk'' were stranded on the island after it struck Half Moon Reef. After a longboat with 11 seamen which had been despatched to go for help had failed to return, the remaining survivors constructed a sloop from the wreckage, which they named the ''Sloepie''. Of the 88 who survived the ordeal, 82 arrived in Batavia on 30 April 1728. During admiralty surveys of the north-west coast in 1840, crew from HMS ''Beagle'' discovered a brass gun of about three pounds calibre and an iron swivel on which paint was still adhered. Captain Stokes with Commander John Clements Wickham named the place Gun Island.〔 p. 15〕 They also discovered several coins, including one dated about 1707 and another dated 1720. Also seen was what appeared to be the beam of a ship with an iron bolt through it, and glass bottles and clay pipes. The material was presumed to have been left there by the ''Zeewyk'' castaways, 112 years earlier. In 1883, Charles Edward Broadhurst, who had been granted a lease for guano export, discovered several campsites and seal bones there, which had evidentially been killed for sustenance by the Zeewyk crew. Gun Island was one of the most heavily worked islands of the Abrolhos Islands for guano.〔(【引用サイトリンク】title=Zeewijk )〕 Guano workings continued on a commercial scale from the 1880s to the 1920s, and again in the mid-1940s. A stone jetty built for loading guano on the south-eastern corner is still intact. A yacht, the ''Nautilus'' was wrecked at Gun Island in 1897.〔(【引用サイトリンク】title=Abrolhos Islands Shipwrecks )〕 A stratigraphic test well was drilled on Gun Island (28º53'30.11"S, 113º51'27.0"E) by BP Petroleum Development Australia in June–November 1968. It was drilled within the Perth Basin and reached a total depth (TD) of 3725 m (12,220 ft). The extent of the drilling platform near the wharf can still be seen on satellite images today. 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「Gun Island」の詳細全文を読む スポンサード リンク
