How submarine channels (re)shape continental margins
Journal of Sedimentary Research, 2020ABSTRACTSubmarine landscapes, like their terrestrial counterparts, are sculpted by autogenic sedimentary processes toward morphologies at equilibrium with their allogenic controls. While submarine channels and nearby, inter-channel continental-margin areas share boundary conditions (e.g., terrestrial sediment supply, tectonic deformation), there are ...

Curvature-induced secondary flow in submarine channels
Environmental Fluid Mechanics, 2014The curvature-driven secondary flow in sinuous submarine channels has been a subject of considerable interest and controversy. Here, results from numerical model studies involving saline flow in laboratory-scale channels are presented. A 3D finite volume model of density and turbidity currents is used and simulations are run with different inflow ...

Submarine channels act as the main conduits for the transport of sediment to deep‐water basins by sediment gravity flows. The interplay between fault‐related deformation and the initiation and development of the channels is poorly known. Here, we present

Marine Geology, 2006
Submarine channels have long been considered analogous to meandering fluvial channels due to their similar planform geometry, and this has given rise to strong analogies in terms of the fluid dynamics of these channel types. However, there is a paucity of direct measurements detailing the structure of velocity or sediment concentration, and nothing is ...

Two-channel submarine carrier telegraph system
Electrical Engineering, 1950ANEW 2-channel carrier telegraph system for short submarine telegraph cables has been developed for the Western Union Key West-Havana cables, about 100 nautical miles in length and with attenuations up to 80 decibels at 1,000 cycles per second. It utilizes standard land-line frequency-modulation channel terminal equipment and provides 50-cycle ...

Submarine channel response to intrabasinal tectonics: The influence of lateral tilt
AAPG Bulletin, 2010Lateral tilting is a common deformation style in extensional basins; its influence on subaerial channels is, to a degree, understood and may be significant, controlling the style of channel development and the resultant sand-body architecture. Growth faulting and lateral tilting in turbidite channel systems have been demonstrated from three-dimensional

Submarine lava tubes and channels
Bulletin of Volcanology, 1986High-resolution, side-looking sonar surveys of the East Pacific rise and seamounts in the eastern Pacific have revealed the common presence of lava tubes and channels in seafloor volcanic terrains. Tube and channel systems commonly issue from small volcanic cones or domes, are continuous for distances of 1–3 km, and are considered to be important in ...

Submarine channel evolution: active channels in fjords, British Columbia, Canada
Geo-Marine Letters, 2012Seafloor channel systems are well developed in several British Columbia (Canada) fjords, including Knight, Bute and Toba inlets. The channels are active conduits for turbidity currents during episodic failures of delta fronts at the fjord heads. Recently acquired swath multibeam bathymetric data enabled a complete and detailed assessment of the form of

Controls on sinuosity evolution within submarine channels
Geology, 2008The planform geometry of submarine channels commonly exhibits a spatio-temporal stability generally not observed in fluvial channels. As such, submarine channels tend to lack the meander loop cutoffs and frequent avulsion history typical of fluvial channels. fluvial sinuosity develops through inner-bend deposition and outer-bend erosion.
