A shallow bank in the central North Sea between Great Britain and Denmark. The name comes from the Dutch word for a two-masted North Sea fishing boat. At the 40m isobath, it is about 300km long and 130km wide at its widest point, with a shallow depth of 17-37m. It was formed when a huge moraine was submerged by a postglacial transgression, and its surface is covered with glacial deposits such as gravel, with mammoth fossils and peat widely distributed. It is a spawning ground for fish, making it a world-class fishing ground, and trawlers land mainly herring, cod, and flounder. Source: Heibonsha World Encyclopedia, 2nd Edition Information |
北海中央部のイギリスとデンマークの間にある浅堆(せんたい)。語源は2本マストの北海漁船を指すオランダ語。40m等深線では長さ約300km,最大幅約130kmに及び,水深は17~37mと浅い。巨大なモレーン(堆石)が後氷期の海進によって沈水して形成され,表層は砂利などの氷河堆積物でおおわれ,マンモスの化石や泥炭などが広く分布する。魚類の産卵場となるため世界的な漁場となり,トロール船でニシン,タラ,ヒラメを中心に水揚げされる。
