Viola (trawler)
The ''Viola'' is a steam trawler built in 1906 at Hull. She is the oldest surviving steam trawler in the world. During her long career, she was known as HMT ''Viola'', ''Kapduen'', and ''Dias''. She is currently beached at Grytviken in South Georgia, though there are currently plans afoot to return her to Hull. History Cook, Welton & Gemmell of Beverley built ''Viola'' for the Hellyer Steam Fishing Company in 1906. After launching, she was floated down the River Hull to Hull where the engineering firm of Amos & Smith fitted her with steam engines. She burnt coal until 1956 when she was converted to oil. She was part of the Hellyer Steam Fishing Company's North Sea fleet, and like much of Hellyer's fleet was named after a Shakespearean character. Hellyer trawlers stayed out at sea for weeks at a time, transferring their catch to a fleet of five fast steam cutters that commuted between the fishing grounds and the fish markets of eastern England. ''Viola'' was regularly at ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grytviken Hg Viola Albatros Cropped
Grytviken ( ) is a settlement on South Georgia in the South Atlantic and formerly a whaling station and the largest settlement on the island. It is located at the head of King Edward Cove within the larger Cumberland East Bay, considered the best harbour on the island. The location's name, meaning "pot bay", was coined in 1902 by the Swedish Antarctic Expedition and documented by the surveyor Johan Gunnar Andersson, after the expedition found old English try pots used to render seal oil at the site. Settlement was re-established on 16 November 1904 by Norwegian Antarctic explorer Carl Anton Larsen on the long-used site of former whaling settlements. Grytviken is built on a substantial area of sheltered, flat land and has a good supply of fresh water. Although it was the largest settlement on South Georgia, the island's administration was based at the nearby British Antarctic Survey research station at King Edward Point. The whaling station closed in December 1966 when dwindlin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
U-boat
U-boats were naval submarines operated by Germany, particularly in the First and Second World Wars. Although at times they were efficient fleet weapons against enemy naval warships, they were most effectively used in an economic warfare role (commerce raiding) and enforcing a naval blockade against enemy shipping. The primary targets of the U-boat campaigns in both wars were the merchant convoys bringing supplies from Canada and other parts of the British Empire, and from the United States, to the United Kingdom and (during the Second World War) to the Soviet Union and the Allied territories in the Mediterranean. German submarines also destroyed Brazilian merchant ships during World War II, causing Brazil to declare war on both Germany and Italy on 22 August 1942. The term is an anglicised version of the German word ''U-Boot'' , a shortening of ''Unterseeboot'' ('under-sea-boat'), though the German term refers to any submarine. Austro-Hungarian Navy submarines were also kno ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Barents Sea
The Barents Sea ( , also ; no, Barentshavet, ; russian: Баренцево море, Barentsevo More) is a marginal sea of the Arctic Ocean, located off the northern coasts of Norway and Russia and divided between Norwegian and Russian territorial waters.World Wildlife Fund, 2008. It was known among Russians in the Middle Ages as the Murman Sea ("Norse Sea"); the current name of the sea is after the historical Netherlands, Dutch navigator Willem Barentsz. The Barents Sea is a rather shallow Continental shelf, shelf sea, with an average depth of , and it is an important site for both fishing and hydrocarbon exploration.O. G. Austvik, 2006. It is bordered by the Kola Peninsula to the south, the shelf edge towards the Norwegian Sea to the west, and the archipelagos of Svalbard to the northwest, Franz Josef Land to the northeast and Novaya Zemlya to the east. The islands of Novaya Zemlya, an extension of the northern end of the Ural Mountains, separate the Barents Sea from the Kar ...

Iceland
Iceland ( is, Ísland; ) is a Nordic island country in the North Atlantic Ocean and in the Arctic Ocean. Iceland is the most sparsely populated country in Europe. Iceland's capital and largest city is Reykjavík, which (along with its surrounding areas) is home to over 65% of the population. Iceland is the biggest part of the Mid-Atlantic Ridge that rises above sea level, and its central volcanic plateau is erupting almost constantly. The interior consists of a plateau characterised by sand and lava fields, mountains, and glaciers, and many glacial rivers flow to the sea through the lowlands. Iceland is warmed by the Gulf Stream and has a temperate climate, despite a high latitude just outside the Arctic Circle. Its high latitude and marine influence keep summers chilly, and most of its islands have a polar climate. According to the ancient manuscript , the settlement of Iceland began in 874 AD when the Norwegian chieftain Ingólfr Arnarson became the first p ...

Northumberland
Northumberland () is a county in Northern England, one of two counties in England which border with Scotland. Notable landmarks in the county include Alnwick Castle, Bamburgh Castle, Hadrian's Wall and Hexham Abbey. It is bordered by land on three sides; by the Scottish Borders region to the north, County Durham and Tyne and Wear to the south, and Cumbria to the west. The fourth side is the North Sea, with a stretch of coastline to the east. A predominantly rural county with a landscape of moorland and farmland, a large area is part of Northumberland National Park. The area has been the site of a number of historic battles with Scotland. Name The name of Northumberland is recorded as ''norð hẏmbra land'' in the Anglo-Saxon Chronicle, meaning "the land north of the Humber". The name of the kingdom of ''Northumbria'' derives from the Old English meaning "the people or province north of the Humber", as opposed to the people south of the Humber Estuary. History ...

Whitby
Whitby is a seaside town, port and civil parish in the Scarborough borough of North Yorkshire, England. Situated on the east coast of Yorkshire at the mouth of the River Esk, Whitby has a maritime, mineral and tourist heritage. Its East Cliff is home to the ruins of Whitby Abbey, where Cædmon, the earliest recognised English poet, lived. The fishing port emerged during the Middle Ages, supporting important herring and whaling fleets, and was where Captain Cook learned seamanship and, coincidentally, where his vessel to explore the southern ocean, ''The Endeavour'' was built.Hough 1994, p. 55 Tourism started in Whitby during the Georgian period and developed with the arrival of the railway in 1839. Its attraction as a tourist destination is enhanced by the proximity of the high ground of the North York Moors national park and the heritage coastline and by association with the horror novel '' Dracula''. Jet and alum were mined locally, and Whitby jet, which was mined by th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Naval Trawler
Naval trawlers are vessels built along the lines of a fishing trawler but fitted out for naval purposes; they were widely used during the First and Second World Wars. Some—known in the Royal Navy as "Admiralty trawlers"— were purpose-built to naval specifications, others adapted from civilian use. Fishing trawlers were particularly suited for many naval requirements because they were robust vessels designed to work heavy trawls in all types of weather, and had large clear working decks. A minesweeper could be created by replacing the trawl with a mine sweep. Adding depth charge racks on the deck, ASDIC sonar below, and a or gun in the bow equipped the trawler for anti-submarine duties. History Armed trawlers were also used to defend fishing groups from enemy aircraft or submarines. The smallest civilian trawlers were converted to danlayers. Contemporary Some nations still use armed trawlers for fisheries protection and patrol. The Indian Navy used naval trawlers for ...

Hydrophone
A hydrophone ( grc, ὕδωρ + φωνή, , water + sound) is a microphone designed to be used underwater for recording or listening to underwater sound. Most hydrophones are based on a piezoelectric transducer that generates an electric potential when subjected to a pressure change, such as a sound wave. Some piezoelectric transducers can also serve as a sound projector, but not all have this capability, and some may be destroyed if used in such a manner. A hydrophone can detect airborne sounds, but will be insensitive because it is designed to match the acoustic impedance of water, a denser fluid than air. Sound travels 4.3 times faster in water than in air, and a sound wave in water exerts a pressure 60 times that exerted by a wave of the same amplitude in air. Similarly, a standard microphone can be buried in the ground, or immersed in water if it is put in a waterproof container, but will give poor performance due to the similarly bad acoustic impedance match.

Depth Charge
A depth charge is an anti-submarine warfare (ASW) weapon. It is intended to destroy a submarine by being dropped into the water nearby and detonating, subjecting the target to a powerful and destructive Shock factor, hydraulic shock. Most depth charges use explosive, high explosive charges and a fuze set to detonate the charge, typically at a specific depth. Depth charges can be dropped by ships, patrol aircraft, and helicopters. Depth charges were developed during World War I, and were one of the first viable methods of attacking a submarine underwater. They were widely used in World War I and World War II, and remained part of the anti-submarine arsenals of many navies during the Cold War, during which they were supplemented, and later largely replaced, by anti-submarine homing torpedoes. A depth charge fitted with a nuclear warhead is also known as a "nuclear depth bomb". These were designed to be dropped from a patrol plane or deployed by an anti-submarine missile from a s ...
