Some new evidence on the origin of the Zeeland Ridges
bookPart
Survey campaigns in an area off the Zeeland coast in the south-eastern part of the Southern Bight with sub-bottom profilers and coring and drilling equipment resulted in relatively detailed information on the sub-seabed conditions. Our data shed some new light on the origin of at least some of the ridges, investigated before by Baak (1936) and Houbolt (1968). Several of the modern Zeeland ridges seem to have been formed essentially by sand accumulation around small pre-existing sediment bodies. One of these so-called 'initial ridges' has been dated as early Atlantic. The sand which makes up the bulk of the modern ridges contains several mollusc species that are no longer living-or are very rare now-in the Southern Bight. This suggests that the ridge formation was essentially completed some time ago, before the deposition of up to 2000 years old, slightly clayey, lee-side deposits.
