The Dogger Bank is an extensive sublittoral sandbank in the southern North Sea formed by glacial processes and submergence through sea-level rise. A large part of the southern area of the bank is covered by water seldom deeper than 20 m below chart datum. The bank is non-vegetated and comprises moderately mobile, clean sandy sediments. It is likely that the fauna of the bank has been impacted by bottom-trawling which may have reduced the number of long-lived or fragile organisms, and resulted in a community dominated by robust short-lived invertebrates including polychaetes such as Nephtys cirrosa. However, the gross physical structure of the bank is intact, and the biology is likely to be representative of the habitat.
