Purdy Islands
The Purdy Islands (or Mwilitau Islands) are an uninhabited island group in the Bismarck Sea, belonging to the people of M'Buke Island in Manus, Papua New Guinea. The Purdy Islands, Mole, Mouse, Rat, plus Bat and Alim (or North Bat and South Bat), form part of the Admiralty Islands group, in Manus Province. History The islands are owned by the Mbuke people. They were named after hydrographer John Purdy by his friend Captain Abraham Bristow on 16 February 1817. Bat Island was the site of RAAF radar station 340 RS between March 1944 and April 1944 during the Second World War. It was one of five such radar stations located within the Admiralty Islands to support the American Invasion. Bat Island proved to be a very dangerous location because it was infested with rats that carried mites which in turn carried Scrub typhus. The majority of the 30 or so strong unit succumbed to Scrub typhus and the station was abandoned after just over a month of service. A contingent of survivors and ...

Bismarck Sea
The Bismarck Sea (, ) lies in the southwestern Pacific Ocean within the nation of Papua New Guinea. It is located northeast 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. Geography Like the Bismarck Archipelago, it is named in honour of the first German Chancellor Otto von Bismarck. The Bismarck Archipelago extends round to the east and north of the sea, enclosing the Bismarck Sea and separating it from the Southern Pacific Ocean. To the south it is linked to the Solomon Sea by the Vitiaz Strait. Official boundaries The International Hydrographic Organization defines the Bismarck Sea as "that area of the Pacific Ocean, South Pacific Ocean off the northeast coast of New Guinea", with the following limits: ''On the North and East.'' By the Northern and Northeastern coasts of the islands of New Ireland (island), New Ireland, New Hanover Island, New Hanover, the Admiralty I ...

Hydrography
Hydrography is the branch of applied sciences which deals with the measurement and description of the physical features of oceans, seas, coastal areas, lakes and rivers, as well as with the prediction of their change over time, for the primary purpose of safety of navigation and in support of all other marine activities, including economic development, security and defense, scientific research, and environmental protection. History The origins of hydrography lay in the making of charts to aid navigation, by individual mariners as they navigated into new waters. These were usually the private property, even closely held secrets, of individuals who used them for commercial or military advantage. As transoceanic trade and exploration increased, hydrographic surveys started to be carried out as an exercise in their own right, and the commissioning of surveys was increasingly done by governments and special hydrographic offices. National organizations, particularly navies, realized ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Purdy (hydrographer)
John Purdy (1773–1843) was an important English hydrographer. His work and influence extended beyond hydrography with the coinage of the term pharology, the study of modern lighthouses and their designs. Purdy's work ''Memoir, descriptive and explanatory, to accompany the New Chart of the Atlantic Ocean'' was adapted and improved; continuing to be released in its fifteenth edition fifty years after his death. Life The son of a bookseller at Norwich, Purdy took up the study of naval charts and similar subjects. Before 1812 he succeeded De la Rochette as hydrographer to Messrs. Laurie & Whittle, of 53 Fleet Street, London. Purdy does not seem to have taken part in hydrographic expeditions himself, and his work consisted in writing works and constructing charts based upon the reports of others; but eventually he became a leading authority of his time on hydrography. He was mainly instrumental in bringing ''Rennell's Current'' before the notice of navigators, and in 1832 James ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Abraham Bristow
Abraham Bristow (c1771-1846) was a British mariner, sealer and whaler. In August 1806 he discovered the Auckland Islands.

Radar
Radar is a detection system that uses radio waves to determine the distance (''ranging''), angle, and radial velocity of objects relative to the site. It can be used to detect aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations, and terrain. A radar system consists of a transmitter producing electromagnetic waves in the radio or microwaves domain, a transmitting antenna, a receiving antenna (often the same antenna is used for transmitting and receiving) and a receiver and processor to determine properties of the objects. Radio waves (pulsed or continuous) from the transmitter reflect off the objects and return to the receiver, giving information about the objects' locations and speeds. Radar was developed secretly for military use by several countries in the period before and during World War II. A key development was the cavity magnetron in the United Kingdom, which allowed the creation of relatively small systems with sub-meter resolution. Th ...
