Room 40
Room 40, also known as 40 O.B. (old building; officially part of NID25), was the cryptanalysis section of the British Admiralty during the First World War. The group, which was formed in October 1914, began when Rear-Admiral Henry Oliver, the Director of Naval Intelligence, gave intercepts from the German radio station at Nauen, near Berlin, to Director of Naval Education Alfred Ewing, who constructed ciphers as a hobby. Ewing recruited civilians such as William Montgomery, a translator of theological works from German, and Nigel de Grey, a publisher. It was estimated that during the war Room 40 decrypted around 15,000 intercepted German communications from wireless and telegraph traffic. Most notably the section intercepted and decoded the Zimmermann Telegram, a secret diplomatic communication issued from the German Foreign Office in January 1917 that proposed a military alliance between Germany and Mexico. Its decoding has been described as the most significant intellig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Moray Firth
The Moray Firth (; , or ) is a roughly triangular inlet (or firth) of the North Sea, north and east of Inverness, which is in the Highland council area of the north of Scotland. It is the largest firth in Scotland, stretching from Duncansby Head (near John o' Groats) in the north, in the Highland council area, and Fraserburgh in the east, in the Aberdeenshire council area, to Inverness and the Beauly Firth in the west. Therefore, three council areas have Moray Firth coastline: Highland to the west and north of the Moray Firth and Highland, Moray and Aberdeenshire to the south. The firth has more than of coastline, much of which is cliff. Etymology The firth is named after the 10th-century Province of Moray, whose name in turn is believed to derive from the sea of the firth itself. The local names ''Murar'' or ''Morar'' are suggested to derive from , the Gaelic for sea, whilst ''Murav'' and ''Morav'' are believed to be rooted in Celtic words (sea) and (side), co ...

Outer Silver Pit
The Outer Silver Pit is a west-to-east valley in the bed of the North Sea. Its widest part is east of Flamborough Head in England. It is between the Dogger Bank and the ridge dividing the northern from the southern North Sea basins, which runs between Norfolk and Friesland. When the sea level was lower (such as in the Ice Age) it was a lake in Doggerland, and sea-bed-penetrating sonar bathymetry has found its shorelines and courses and estuaries of rivers that ran into it from the high land of the Dogger Bank; it overflowed into a river at its west end.''Mapping Doggerland'', ed. Vincent Gaffney and others, publ. Archaeopres2007, Bed of the Rhine? In the Cromerian Stage, before more recent glaciation had influenced the area, a ridge of high ground, the Weald-Artois Anticline, joined the Upper Cretaceous chalk in Kent, England to that of the Boulonnais at '' Cap Blanc-Nez'' in the Pas de Calais, France.

Dogger Bank
Dogger Bank ( Dutch: ''Doggersbank'', German: ''Doggerbank'', Danish: ''Doggerbanke'') is a large sandbank in a shallow area of the North Sea about off the east coast of England. During the last ice age, the bank was part of a large landmass connecting mainland Europe and the British Isles, now known as Doggerland. It has long been known by fishermen to be a productive fishing bank; it was named after the '' doggers'', medieval Dutch fishing boats especially used for catching cod. At the beginning of the 21st century, the area was identified as a potential site for a UK round 3 wind farm, being developed as Dogger Bank Wind Farm. Name The name Dogger Bank was first recorded in the mid-17th century. It is probably derived from the word "'' dogger''" used for a two-masted boat of the type that trawled for fish in the area in medieval times. The area has similar names in Dutch, German, Swedish, and Danish. Geography The bank extends over about , and is about in exte ...
