Abstract

At the margins of eroding salt marshes on the German North Sea coast, shell layers have been identified and interpreted as storm surge deposits. This interpretation is supported by cesium dating of the younger part of the sequence. The dates indicate an almost constant sedimentation rate over the last thirty-five years. Extrapolation of this rate to older storm surge deposits enables the identification of individual storm surge strata back to 1926.
