Vitiaz Strait is a strait between New Britain and the Huon Peninsula, northern New Guinea. [1] [2]
The Vitiaz Strait was so named by Nicholai Nicholaievich Mikluho-Maklai to commemorate the Russian corvette Vitiaz in which he sailed from October 1870 by way of South America and the Pacific Islands reaching Astrolabe Bay in September 1871. [3]
The 1200 m deep Vitiaz Strait "was a focus of attention by Australian and USA oceanographers on voyages in 1985, 1986, 1988, 1991 and 1992 as part of the Western Equatorial Pacific Ocean Circulation Study, WEPOCS". [4]
The New Guinea Coastal Undercurrent transports "high-salinity, low-tritium, high-oxygen, low-nutrient water from the Solomon Sea northwestward along the north coast of Papua New Guinea through the Vitiaz Strait". [5]
However, the surface layer current running through the strait, the New Guinea Coastal Current, experiences a seasonal reversal. In boreal summer (northern hemisphere summer) characterized by the south-easterly monsoon, the westward current dominates; during boreal winter (northern hemisphere winter) under the influence of the northwesterly monsoonal winds, the eastward flow dominates. [6]
Abel Tasman sighted Umboi Island in the Vitiaz Strait in 1643 but failed to realise that the Strait separated the island from the coast of New Guinea. [7] William Dampier charted the passage now named Dampier Strait between Umboi Island and New Britain in 1700 [8] Dampier had established that the land mass he named New Britain was an island. As he sailed northwesterly through the passage, Dampier charted and named various islands which lay between the Dampier and Vitiaz Straits: Sir George Rook's Island (later Rooke Island, now Umboi Island), Long Island (Arop Island) and Crown Island. [9]
During the New Guinea Campaign (1942-1945), control of the Vitiaz Strait took on strategic military importance. The Japanese landed two battalions at Lae and Salamaua on the Huon Gulf on 8 March 1942 giving them control of the Dampier and Vitiaz Straits. [10] Japanese forces lost control of the Vitiaz and Dampier Straits after the capture of Finschhafen by Australian troops and the later landing of American forces on New Britain (December 1943). [11] General Douglas MacArthur announced that Rooke Island (now called Umboi Island) had been occupied on Saturday 12 February 1944 by American forces who met no opposition. [12] [13] Allied control was made secure by landings in the Admiralty Islands on 29 February 1944. [14]
The prehistory of Papua New Guinea can be traced to about 50,000–60,000 years ago, when people first migrated towards the Australian continent. The written history began when European navigators first sighted New Guinea in the early part of the 17th century.
Melanesia is a subregion of Oceania in the southwestern Pacific Ocean. It extends from New Guinea in the west to the Fiji Islands in the east, and includes the Arafura Sea.
New Britain is the largest island in the Bismarck Archipelago, part of the Islands Region of Papua New Guinea. It is separated from New Guinea by a northwest corner of the Solomon Sea and from New Ireland by St. George's Channel. The main towns of New Britain are Rabaul/Kokopo and Kimbe. The island is roughly the size of Taiwan.
The Bismarck Sea lies in the south-western Pacific Ocean within the Papua New Guinean exclusive economic zone. It is located north-east of the island of New Guinea and south of the Bismarck Archipelago. It has coastlines in districts of the Islands Region, Momase Region, and Papua Region.
Dampier Strait may refer to either of two different straits with the same name which are located near the same island of New Guinea:
The Catholic Church in Papua New Guinea is part of the worldwide Catholic Church, under the spiritual leadership of the Pope in Rome. Papua New Guinea has approximately two million Catholic adherents, approximately 27% of the country's total population.
Umboi is a volcanic island between the mainland of Papua New Guinea and the island of New Britain. It is separated from New Britain by the Dampier Strait, and Huon Peninsula and New Guinea by the Vitiaz Strait. It has an elevation of 1,335 metres.
Huon Peninsula is a large rugged peninsula on the island of New Guinea in Morobe Province, eastern Papua New Guinea. It is named after French explorer Jean-Michel Huon de Kermadec. The peninsula is dominated by the steep Saruwaged and Finisterre and Cromwell Mountains. The nearest large town is the Morobe provincial capital Lae to the south, while settlements on the north coast include the former German town of Finschhafen, the district capital of Wasu, Malalamai and Saidor with its World War II era Saidor Airport.
The 1998 Papua New Guinea earthquake occurred on July 17 with a moment magnitude of 7.0 and a maximum Mercalli intensity of VIII (Severe). The event occurred on a reverse fault near the north coast region of Papua New Guinea, 25 kilometers (16 mi) from the coast near Aitape and caused a large undersea landslide which caused a tsunami that hit the coast, killing between at least 2,183 and 2,700 people and injuring thousands.
Papua New Guinea, a sovereign state in Oceania, is the most linguistically diverse country in the world. According to Ethnologue, there are 840 living languages spoken in the country. In 2006, Papua New Guinea Prime Minister Sir Michael Somare stated that "Papua New Guinea has 832 living languages ."
The white-striped dorcopsis or greater forest wallaby is a species of marsupial in the family Macropodidae. It is found in the northern part of Western New Guinea, Indonesia and Papua New Guinea. It is a common species in suitable tropical forest habitat and the IUCN lists its conservation status as being of "Least concern".
Dampier Strait in Papua New Guinea separates Umboi Island and New Britain, linking the Bismarck Sea to the north with the deeper Solomon Sea to the south.
New Guinea is the world's second-largest island, with an area of 785,753 km2 (303,381 sq mi). Located in Melanesia in the southwestern Pacific Ocean, the island is separated from Australia by the 150-kilometre wide Torres Strait, though both landmasses lie on the same continental shelf, and were united during episodes of low sea level in the Pleistocene glaciations as the combined landmass of Sahul. Numerous smaller islands are located to the west and east. The island's name was given by Spanish explorer Yñigo Ortiz de Retez during his maritime expedition of 1545 due to the resemblance of the indigenous peoples of the island to those in the African region of Guinea.
Kelanoa Harbour is a harbour on the north coast of the Huon Peninsula in Papua New Guinea serving the town of Kelanoa. It is a large bay with an impenetrable reef and a small island.
Vityaz was a steam corvette of the Baltic Fleet of the Imperial Russian Navy. Later renamed Skobelev, Vityaz spent much of its career as an oceanographic research vessel, completing two circumnavigations of the world in this capacity.
On the morning of March 13, 1888, an explosion took place on Ritter Island, a small volcanic island in the Bismarck and Solomon Seas, between New Britain and Umboi Island. The explosion resulted in the collapse of most of the island and generated a tsunami with runups of up to 15 meters (49 ft) that caused damage more than 700 kilometers (430 mi) away and killed anywhere between 500 and 3,000 on neighboring islands, including scientists and explorers. This event is the largest volcanic island sector collapse in recent history.
Low-latitude western boundary currents (LLWBC) are western boundary currents located between the subtropical gyres, within 20° of the equator. They are important for closing the tropical circulation driven by the equatorial zonal flow, and facilitate inter-ocean transport between the subtropical gyres. They occur in regions of negative (positive) wind stress curl in the southern (northern) hemisphere, and originate at the western bifurcation point of the South or North Equatorial Current. They are typically equatorward (cyclonic) as opposed to sub-tropical western boundary currents, which tend to be poleward (anticyclonic). Some well-known examples include the Mindanao Current (MC) and the East African Coastal Current (EACC).
On September 9, 2002, a magnitude 7.6 earthquake struck off the coast of Wewak, Sandaun Province, Papua New Guinea. The shallow reverse earthquake triggered a local tsunami measuring 5 meters high. The disaster resulted in at least 6 deaths, 70 injuries and building damage.
