Abstract
Continuous high-resolution echosounding of deep sea sediments up to a maximum penetration of 200 m images sedimentation patterns and processes related to climatic and oceanographic changes. A new technical concept was applied to transmission and reception of high-frequency signals and requires arevision and adaption of classical stratigraphic processing techniques and interpretative approaches with respect to signal length and bandwidth. Selected methods are discussed in comparison to the frequency range and signal shape used in conventional (marine) seismics.
