Dogger Bank (Dutch: ''Doggersbank'', German: ''Doggerbank'', Danish: ''Dogger banke'') is a large sandbank in a shallow area of the North Sea about off the east coast of England. The bank extends over approximately , with its dimensions being about long and up to broad. The water depth ranges from 15 to 36 metres (from 49 to 118 feet), about shallower than the surrounding sea. It has long been known by fishermen to be a productive fishing bank; it was named after the ''doggers'', Old Dutch fishing boats especially used for catching cod. ==Geography== Geologically, the feature is most likely a moraine, formed during the Pleistocene.〔 At differing times during the last ice age it was either joined to the mainland or an island. The bank was part of a large landmass, known as Doggerland, which connected Britain to the European mainland until it was flooded some time after the end of the last ice age.〔(University of Sussex, School of Life Sciences ), C1119 Modern human evolution, Lecture 6, slide 23 〕 Fishing trawlers working the area have dredged up large amounts of moor peat, remains of mammoth and rhinoceros, and occasionally Paleolithic hunting artefacts. In 1931, the largest earthquake ever recorded in the United Kingdom took place below the bank, measuring 6.1 on the Richter scale. Its focus was 23 km beneath the bank, and the quake was felt in countries all around the North Sea, causing damage across eastern England. South of Dogger Bank is the Cleaver Bank. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Dogger Bank」の詳細全文を読む スポンサード リンク
