The laboratory work to the dynamics of turbidity currents, outlined in this volume, is the first experimental investigation of the nature of downslape gravity-driven currents of suspended sediments which are reflected/ deflected against obstacles such as seamounts oceanfloor slopes. Scientists and researchers working on the interpretation and understanding of features occurring in sequence stratigraphic sections will find useful clues. Background to the research and review of density and turbidity current flow.- Experimental study of the incidence of density currents upon ramps and obstacles.- A model for the incidence of gravity currents on obstructions to flow and a discussion of its applicability to modern and ancient turidite systems. The author's laboratorial experiments are dealing with an important aspect of sequence stratigraphic interpretations - the physical behaviour of submarine currents bouncing against an obstacle, e.g. a seamount or barrier. In this well illustrated volume scientists and students will find useful clues for their interpretation of sequence stratigraphic sections.
