Abstract |
Sea-level data collected by Jelgersma (1961) from Zeeland in the southwestern Netherlands show an anomalously high time-depth position with respect to sea-level curves established for the rest of the Netherlands. Until now, it was not clear whether this was related to differential crustal movements, a higher tidal range and/or to groundwater-influenced peat growth above contemporaneous sea level. New radiocarbon dates from the base of the basal peat in Zeeland and the adjacent estuarine flood plain of the River Schelde in Belgium have a considerably lower time-depth position than the original data of Jelgersma (1961). Comparison of the lowest mean sea-level (MSL) time-depth points from the study area with a reference MSL error band for the western Netherlands yields a maximum crustal uplift of Zeeland relative to the western Netherlands of about 0.17 m/1000 yr over the last 8000 yrs cal B.P. |
