Operation Zarin
Operation Zarin ( en, Tsarina []) was a German Naval mine, minelaying operation off the north-western coast of the islands of Novaya Zemlya in the Arctic Ocean. The operation was conducted between 24 September and 28 September 1942 by the German heavy cruiser escorted by the destroyers , , and , because the British had sunk the specialist minelayer ' on 25 August. The mines laid during the operation had little effect. Background Operation Tsar () During Convoy PQ 17 (27 June – 10 July 1942) freighters sailed as far north as possible and used the coasts of Novaya Zemlya as cover to get to Murmansk or Arkhangelsk. In Operation Tsar () the minelayer ' was sent from Kiel to Narvik escorted by the destroyer and the torpedo boats and from 15 to 19 August. ''Ulm'' was to lay a minefield off Cape Zhelaniya, the most northerly point of Novaya Zemlya, after the completion of Operation Wonderland ( 16 August – 5 October 1942). The minefield would force Allied ships to steer more ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Second World War
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
GCHQ
Government Communications Headquarters, commonly known as GCHQ, is an intelligence and security organisation responsible for providing signals intelligence (SIGINT) and information assurance (IA) to the government and armed forces of the United Kingdom. Primarily based at "The Doughnut" in the suburbs of Cheltenham, GCHQ is the responsibility of the country's Secretary of State for Foreign and Commonwealth Affairs (Foreign Secretary), but it is not a part of the Foreign Office and its Director ranks as a Permanent Secretary. GCHQ was originally established after the First World War as the Government Code and Cypher School (GC&CS) and was known under that name until 1946. During the Second World War it was located at Bletchley Park, where it was responsible for breaking the German Enigma codes. There are two main components of the GCHQ, the Composite Signals Organisation (CSO), which is responsible for gathering information, and the National Cyber Security Centre (NCSC), whi ...

Admiralty (United Kingdom)
The Admiralty was a department of the Government of the United Kingdom responsible for the command of the Royal Navy until 1964, historically under its titular head, the Lord High Admiral – one of the Great Officers of State. For much of its history, from the early 18th century until its abolition, the role of the Lord High Admiral was almost invariably put "in commission" and exercised by the Lords Commissioner of the Admiralty, who sat on the governing Board of Admiralty, rather than by a single person. The Admiralty was replaced by the Admiralty Board in 1964, as part of the reforms that created the Ministry of Defence and its Navy Department (later Navy Command). Before the Acts of Union 1707, the Office of the Admiralty and Marine Affairs administered the Royal Navy of the Kingdom of England, which merged with the Royal Scots Navy and the absorbed the responsibilities of the Lord High Admiral of the Kingdom of Scotland with the unification of the Kingdom of Great B ...

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 ...

Kara Sea
The Kara Sea (russian: Ка́рское мо́ре, ''Karskoye more'') is a marginal sea, separated from the Barents Sea to the west by the Kara Strait and Novaya Zemlya, and from the Laptev Sea to the east by the Severnaya Zemlya archipelago. Ultimately the Kara, Barents and Laptev Seas are all extensions of the Arctic Ocean north of Siberia. The Kara Sea's northern limit is marked geographically by a line running from Cape Kohlsaat in Graham Bell Island, Franz Josef Land, to Cape Molotov (Arctic Cape), the northernmost point of Komsomolets Island in Severnaya Zemlya. The Kara Sea is roughly long and wide with an area of around and a mean depth of . Its main ports are Novy Port and Dikson and it is important as a fishing ground although the sea is ice-bound for all but two months of the year. The Kara Sea contains the East-Prinovozemelsky field (an extension of the West Siberian Oil Basin), containing significant undeveloped petroleum and natural gas. In 2014, US gov ...

Sound (geography)
In geography, a sound is a smaller body of water typically connected to a larger sea or ocean. There is little consistency in the use of "sound" in English-language place names. It can refer to an inlet, deeper than a bight and wider than a fjord, or a narrow sea or ocean channel between two bodies of land (similar to a strait), or it can refer to the lagoon located between a barrier island and the mainland. Overview A sound is often formed by the seas flooding a river valley. This produces a long inlet where the sloping valley hillsides descend to sea-level and continue beneath the water to form a sloping sea floor. The Marlborough Sounds in New Zealand are good examples of this type of formation. Sometimes a sound is produced by a glacier carving out a valley on a coast then receding, or the sea invading a glacier valley. The glacier produces a sound that often has steep, near vertical sides that extend deep underwater. The sea floor is often flat and deeper at the ...

Yugorsky Strait
The Yugorsky Strait or Yugor Strait (russian: Югорский Шар, or Yugorsky Shar) is a narrow sound between the Kara Sea and the Pechora Sea. Its maximum width is 10 km and its minimum width only 3 km. Ostrov Storozhevoy, an island 1.6 km in length, lies in the middle of the strait. This sound separates Vaygach Island from the Yugorsky Peninsula on the Russian mainland. The name is derived from Yugaria, an old name for the region to the south of Yugorsky Strait. History The earliest recorded voyage through the Yugorsky Shar, traditionally known as the Arctic "Iron Gateway", into the Kara Sea was made from Nizhny Novgorod by early Russian explorer Uleb in 1032. Russian "Pomors", the coastal dwellers of the White Sea shores, had been exploring this strait since the 11th century. The Arctic's first shipping line, the Great Mangazea Route, from the White Sea to the Ob River and the Yenisei Gulf began operating in the latter part of the 16th century. This li ...
