Benthos supported by the tunnel-valleys of the Southern North Sea
The tunnel-valleys of the southern North Sea are arcuate and linear seabed depressions. The origin of these features has been the subject of much discussion, but they are generally considered to have been formed by subglacial erosion and sediment backfill beneath the outer margins of a receding ice...
