Gutter Sound
Gutter Sound is a location in Orkney, Scotland, part of the vast anchorage of Scapa Flow. It lies to the west of the main harbour between the internal islands of Cava and Fara, and the large outer island of Hoy. Gutter Sound was the one of the sites of the mass-scuttling of the interned Imperial German High Seas Fleet in 1919, and the scene of a major salvage operation in the 1920s. Today the remaining wrecks make the Sound a popular diving location. Location Gutter Sound is a body of water some four miles long and a mile wide at its widest point, and has a depth of around 30 meters in places. It separates Hoy and Cava in the north, and Hoy and Fara in the south, opening onto the Flow between Cava and Fara. In the north it opens out into the Bring Deeps, while the south it joins Weddell Sound, between Fara and Flotta, and to Switha Sound, between Flotta and Hoy. History At the end of the First World War Scapa Flow was the anchorage for the surrendered German High Seas Fle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Orkney
Orkney (; sco, Orkney; on, Orkneyjar; nrn, Orknøjar), also known as the Orkney Islands, is an archipelago in the Northern Isles of Scotland, situated off the north coast of the island of Great Britain. Orkney is 10 miles (16 km) north of the coast of Caithness and has about 70 islands, of which 20 are inhabited.

Compressed Air
Compressed air is air kept under a pressure that is greater than atmospheric pressure. Compressed air is an important medium for transfer of energy in industrial processes, and is used for power tools such as air hammers, drills, wrenches, and others, as well as to atomize paint, to operate air cylinders for automation, and can also be used to propel vehicles. Brakes applied by compressed air made large railway trains safer and more efficient to operate. Compressed air brakes are also found on large highway vehicles. Compressed air is used as a breathing gas by underwater divers. It may be carried by the diver in a high pressure diving cylinder, or supplied from the surface at lower pressure through an air line or diver's umbilical. Similar arrangements are used in breathing apparatus used by firefighters, mine rescue workers and industrial workers in hazardous atmospheres. In Europe, 10 percent of all industrial electricity consumption is to produce compressed air—amountin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Protected Wrecks Of Scotland
Protection is any measure taken to guard a thing against damage caused by outside forces. Protection can be provided to physical objects, including organisms, to systems, and to intangible things like civil and political rights. Although the mechanisms for providing protection vary widely, the basic meaning of the term remains the same. This is illustrated by an explanation found in a manual on electrical wiring: Some kind of protection is a characteristic of all life, as living things have evolved at least some protective mechanisms to counter damaging environmental phenomena, such as ultraviolet light. Biological membranes such as bark on trees and skin on animals offer protection from various threats, with skin playing a key role in protecting organisms against pathogens and excessive water loss. Additional structures like scales and hair offer further protection from the elements and from predators, with some animals having features such as spines or camouflage servi ...

Ports And Harbours Of Scotland
A port is a maritime law, maritime facility comprising one or more Wharf, wharves or loading areas, where ships load and discharge Affreightment, cargo and passengers. Although usually situated on a sea coast or estuary, ports can also be found far inland, such as Port of Hamburg, Hamburg, Port of Manchester, Manchester and Duluth; these access the sea via rivers or canals. Because of their roles as port of entry, ports of entry for immigrants as well as soldiers in wartime, many port cities have experienced dramatic multi-ethnic and multicultural changes throughout their histories. Ports are extremely important to the global economy; 70% of global merchandise trade by value passes through a port. For this reason, ports are also often densely populated settlements that provide the labor for processing and handling goods and related services for the ports. Today by far the greatest growth in port development is in Asia, the continent with some of the World's busiest ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

History Of Orkney
Humans have inhabited Orkney, an archipelago in the north of Scotland, for about 8,800 years: Archeological evidence dates from Mesolithic times. Scandinavian clans dominated the area from the 8th century CE, using the islands as a base for further incursions. In the late 14th century the archipelago became part of Scotland. Prehistoric Orkney As with Prehistoric Scotland generally, hunter gatherers followed the slow retreat of ice age glaciation. The rapid spread of Neolithic culture up the western seaways soon brought early farming settlements and Megalithic culture. The prevalent use of the local sandstone, found ready split into convenient building slabs on the shore, preserved numerous structures from this period, including prehistoric villages, brochs, souterrain structures, chambered cairns and standing stones. The oldest stone house still standing in northern Europe (occupied from 3500 BC to 3100 BC) is at Knap of Howar on the island of Papa Westray, with walls intact ...

Landforms Of Orkney
A landform is a natural or anthropogenic land feature on the solid surface of the Earth or other planetary body. Landforms together make up a given terrain, and their arrangement in the landscape is known as topography. Landforms include hills, mountains, canyons, and valleys, as well as shoreline features such as bays, peninsulas, and seas, including submerged features such as mid-ocean ridges, volcanoes, and the great ocean basins. Physical characteristics Landforms are categorized by characteristic physical attributes such as elevation, slope, orientation, stratification, rock exposure and soil type. Gross physical features or landforms include intuitive elements such as berms, mounds, hills, ridges, cliffs, valleys, rivers, peninsulas, volcanoes, and numerous other structural and size-scaled (e.g. ponds vs. lakes, hills vs. mountains) elements including various kinds of inland and oceanic waterbodies and sub-surface features. Mountains, hills, plateaux, and plains are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Battleship
A battleship is a large armored warship with a main battery consisting of large caliber guns. It dominated naval warfare in the late 19th and early 20th centuries. The term ''battleship'' came into use in the late 1880s to describe a type of ironclad warship,Stoll, J. ''Steaming in the Dark?'', Journal of Conflict Resolution Vol. 36 No. 2, June 1992. now referred to by historians as pre-dreadnought battleships. In 1906, the commissioning of into the United Kingdom's Royal Navy heralded a revolution in the field of battleship design. Subsequent battleship designs, influenced by HMS ''Dreadnought'', were referred to as "dreadnoughts", though the term eventually became obsolete as dreadnoughts became the only type of battleship in common use. Battleships were a symbol of naval dominance and national might, and for decades the battleship was a major factor in both diplomacy and military strategy.Sondhaus, L. ''Naval Warfare 1815–1914'', .

Light Cruiser
A light cruiser is a type of small or medium-sized warship. The term is a shortening of the phrase "light armored cruiser", describing a small ship that carried armor in the same way as an armored cruiser: a protective belt and deck. Prior to this smaller cruisers had been of the protected cruiser model, possessing armored decks only. While lighter and smaller than other contemporary ships they were still true cruisers, retaining the extended radius of action and self-sufficiency to act independently around the world. Through their history they served in a variety of roles, primarily as convoy escorts and destroyer command ships, but also as scouts and fleet support vessels for battle fleets. Origins and development The first small steam-powered cruisers were built for the British Royal Navy with HMS ''Mercury'' launched in 1878. Such second and third class protected cruisers evolved, gradually becoming faster, better armed and better protected. Germany took a lead in small crui ...

Scuba Diving
Scuba diving is a mode of underwater diving whereby divers use breathing equipment that is completely independent of a surface air supply. The name "scuba", an acronym for "Self-Contained Underwater Breathing Apparatus", was coined by Christian J. Lambertsen in a patent submitted in 1952. Scuba divers carry their own source of breathing gas, usually compressed air, affording them greater independence and movement than surface-supplied divers, and more time underwater than free divers. Although the use of compressed air is common, a gas blend with a higher oxygen content, known as enriched air or nitrox, has become popular due to the reduced nitrogen intake during long and/or repetitive dives. Also, breathing gas diluted with helium may be used to reduce the likelihood and effects of nitrogen narcosis during deeper dives. Open circuit scuba systems discharge the breathing gas into the environment as it is exhaled, and consist of one or more diving cylinders containing breat ...

Wreck Diving
Wreck diving is recreational diving where the wreckage of ships, aircraft and other artificial structures are explored. Although most wreck dive sites are at shipwrecks, there is an increasing trend to scuttle retired ships to create artificial reef sites. Diving to crashed aircraft can also be considered wreck diving. The recreation of wreck diving makes no distinction as to how the vessel ended up on the bottom. Some wreck diving involves penetration of the wreckage, making a direct ascent to the surface impossible for a part of the dive. Reasons for diving wrecks A shipwreck may be attractive to divers for several reasons: * it serves as an artificial reef, which creates a habitat for many types of marine life * it often is a large structure with many interesting parts and machinery, which is not normally closely observable on working, floating vessels * it often has an interesting history * it presents new skill challenges for scuba divers to manage the risks associate ...
