The objective of this session is to bring together a range of researchers including experimentalists, numerical modellers, marine geologists and field geologists, to focus on our current understanding of sedimentary processes and products of deltas, submarine fans and subaquatic sediment gravity flows. Contributions may deal with siliciclastic-fed systems or with carbonate environments, and may cover a wide spectrum of grain sizes. In such settings, the interaction between episodic dip-slope events (e.g. turbidity currents and mass-transport processes), longer-persistent along-slope contouritic processes and/or evolving seabed morphology on even longer geologic timescales result in erosional features and depositional sedimentary sequences, the reconstruction of which provides key information to constrain regional tectonic, geologic and climate history.
We invite presentations that contribute to the advancement of our understanding of sediment dynamics, paleo-reconstruction and natural hazards associated with sedimentary processes in such subaqueous environments. While studies may be regional, we particular welcome comprehensive and interdisciplinary approaches providing new findings of generic significance towards holistic comprehension of: 1. the complex interaction between along and dip-slope processes in subaqueous slope environments, and 2. the flow mechanics and deposition of fine-grained (silts and clays) gravity flow processes and products.
