05-MMG-SS1 Sedimentary Structures of Shelves and Passive Margins

Representative Tilmann Schwenk

Learning Contents:

The central focus of this module is the transport and deposition of sediment particles on passive margins and shelves with respect to external and internal forces, thereby integrating sedimentological, geophysical and actuo-paleontological results. One course is the training of the (integrated) interpretation of all kind of seismo-acoustic data as multibeam, sidescan sonar, sediment echosounder and high-resolution seismic systems. A second course introduces the main features of carbonate and terrigenous sedimentation patterns in tropical and non-tropical shelf environments along latitudinal and bathymetrical traverses. Analysis of sediment dynamics and ecological pattern on shelves provide important links between terrestrial and oceanic responses to global climate forcing. Within the third course sediment dynamics at passive margins are analyzed. In particular, a variety of gravity-driven mass flows and contouritic deposition are discussed in terms of evolutionary models and a processed-based understanding.
