A comprehensive data set of the seafloor relief and superficial sedimentary cover on the Ebro progradational continental slope, NW Mediterranean Sea, reveals that its Late Quaternary building results from complex interrelationships between processes ranging from channel abandonment to incision of inner minor courses, from retrogressive erosion and channel capture to levee cutting and new channel opening, from channel wall sliding to shelf-edge and channel spillover. These processes succeed ones to the others both in time and space conforming a canibalistic frame where the balance between destructive and constructive processes is finally favourable to the last. They result in the formation of the channel-levee complexes characteristic of the Ebro continental slope and base-of-slope

The GEBRA '93 (Geological Evolution of the Bransfield Basin) survey was carried out in December 1993 in the Bransfield Strait (NW Antarctic Peninsula) and adjacent areas, onboard BIO Hespérides. The geophysical data acquired allow to characterize the morphostructure, sediment cover and magnetic anomalies of the SW-NE trending Central Bransfield Basin. Some transverse shifts and tresholds, together with alongbasin volcanic alignments, complicate the morphology and seismic structure of what otherwise would have been a long, continuous axial trough opened on a crust under extension. A major submarine valley, named Gebra Valley has also been identified

The sediment transport in a littoral system Is conditioned by the bathymorfology, sediment type, and by the dynamic regime. Generation of a numerical model including all of these factors, allow us the transport types characterization, and their location in the Maresme Coast (NE Barcelona), for all the different climate regimes

Two different types of sand bodies characterize the Maresme Coast (NE Spain). A longshore submarine sand,bar built by theTordera river output is 6 km long and progressively deepens to 8 m depth. Four littoral bar systems have been generated at decresing depths following the sea level rise from the shelf. These sand bodies are generated by quite different processes: littoral drift; reflective storm waves and rip currents. C14 dating has enabled us to make a chronological frame work for both systems
