Abstract. In this paper we present an algorithm based on wavelet multiscale decomposition, designed to detect lines of maximal gradients in horizontal direction within two-dimensional data sets. The algorithm is capable of identifying layer boundaries within sediment profiles, as demonstrated for artificial as well as two field data sets. Layers are detected with a good resolution within (i) digital images of a deep sea sediment core (IODP-expedition 301, core 15H) and (ii) chemical concentration patterns of recent tidal sediments (North Sea).
