Abstract:

The goal of STRATAFORM is to link short-term biological and physical processes affecting sedimentation event stratigraphy developed over hours to weeks to the stratigraphic geometry and facies distribution of the upper approx. 100 m of continental margin sediments representing approx. 10exp 6 years of preserved record. Three groups of processes have been isolated for study by STRATAFORM investigators 1 shelf sediment dynamics and the development of lithostratigraphy 2 slope processes and their role in shaping geomorphology and 3 stratigraphic sequence generation. Collecting high-resolution seismic reflection data as we have done is at the core of this third approach. All three are linked by our goal of determining how the morphology and facies patterns of the modern sea floor revealed by multibeam bathymetry, backscatter data, and sampling of the shelf and slope compare with the preserved geologic record observed in seismic images and sampled in the subsurface.
