SD1 - Bridging scales: From small-scale morphological and sedimentological features to coast and shelf systems
C. Winter, T. v. Dobeneck, A. Bartholomä
V. Ernstsen, T. Hanebuth, K. Huhn, A. Kopf
Sediment transport pathways from the estuaries and coasts to the shelf seas are governed by various physical and biogeochemical processes across a wide bandwith of spatial and temporal scales. This project aims towards a process-based deterministic understanding of the sediment- and morphodynamics of coastal and shelf systems based on physical and biogeochemical principles. Existing transport concepts and parameterizations of particle dynamics at micro-scales to bedform dynamics and depocenters at kilometer-scales are tested and enhanced.
High-resolution surveys with in-situ technologies including multi-sensor benthic profilers, landers, camera systems, penetrometers, and ship based optical and hydro-acoustic measurements allow us to determine sedimentary physical properties and processes in their natural environment. The effects of steady, seasonal and episodic forcing mechanisms are isolated based on monitoring installations at selected sites in cooperation with national and international partners. Process based numerical models are applied to inter- and extrapolate field data and to simulate inter-relations between processes across scales.
