J. Ehlers et al., STORM-SURGE DEPOSITS IN NORTH-SEA SALT MARSHES DATED BY CS-134 AND CS-137 DETERMINATION, Journal of coastal research, 9(3), 1993, pp. 698-701
At the margins of eroding salt marshes on the German North Sea coast,
shell layers have been identified and interpreted as storm surge depos
its. This interpretation is supported by cesium dating of the younger
part of the sequence. The dates indicate an almost constant sedimentat
ion rate over the last thirty-five years. Extrapolation of this rate t
o older storm surge deposits enables the identification of individual
storm surge strata back to 1926.
