Environmental signal propagation in sedimentary systems across timescales
Earth-surface processes operate across erosionally dominated landscapes and deliver
sediment to depositional systems that can be preserved over a range of timescales. The …

How are subaqueous sediment density flows triggered, what is their internal structure and how does it evolve? Direct observations from monitoring of active flows
PJ Talling, CK Paull, DJW Piper - Earth-Science Reviews, 2013 - Elsevier
Subaqueous sediment density flows are one of the volumetrically most important processes
for moving sediment across our planet, and form the largest sediment accumulations on …

Powerful turbidity currents driven by dense basal layers
Seafloor sediment flows (turbidity currents) are among the volumetrically most important yet
least documented sediment transport processes on Earth. A scarcity of direct observations …

Contemporary sediment-transport processes in submarine canyons
Submarine canyons are morphological incisions into continental margins that act as major
conduits of sediment from shallow-to deep-sea regions. However, the exact mechanisms …

Large-scale sediment waves and scours on the modern seafloor and their implications for the prevalence of supercritical flows
WO Symons, EJ Sumner, PJ Talling, MJB Cartigny… - Marine Geology, 2016 - Elsevier
Abstract Large-scale (20 m to 7 km wavelength) bedforms are common on the seafloor, yet
there is a lack of consensus on how they form and thus what to call them. We conducted …

[HTML][HTML] A comparative study of sediment waves and cyclic steps based on geometries, internal structures and numerical modeling
Although sediment waves cover many levees and canyon floors of submarine fan systems,
their relation to the turbidity currents that formed them is still poorly understood. Over the …

Intrinsic controls on the range of volumes, morphologies, and dimensions of submarine lobes
Submarine lobe dimensions from six different systems are compared: 1) the exhumed
Permian Fan 3 lobe complex of the Tanqua Karoo, South Africa; 2) the modern Amazon fan …

Very large subaqueous sand dunes on the upper continental slope in the South China Sea generated by episodic, shoaling deep-water internal solitary waves
DB Reeder, BB Ma, YJ Yang - Marine Geology, 2011 - Elsevier
Very large subaqueous sand dunes were discovered on the upper continental slope of the
northern South China Sea. The dunes were observed along a single 40km long transect …

Submarine channel initiation, filling and maintenance from sea‐floor geomorphology and morphodynamic modelling of cyclic steps
Advances in acoustic imaging of submarine canyons and channels have provided accurate
renderings of sea‐floor geomorphology. Still, a fundamental understanding of channel …
