How submarine channels (re)shape continental margins

Journal of Sedimentary Research, 2020
ABSTRACTSubmarine 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 ...

Slope Control on Submarine Channel Widths

Journal of Sedimentary Research, 2008
Abstract Submarine channel systems associated with turbidity currents show characteristic variations in channel width and channel slope with distance from source. The most proximal parts are generally formed from pre-existing canyons but these are followed by channels which show segments with two distinct behaviors: (1) sections where channel width is ...

Submarine depth control by individual channel design

Proceedings of the 37th IEEE Conference on Decision and Control (Cat. No.98CH36171), 2002
The analysis of submarine control design under the framework of individual channel design (ICD) is presented. The boat considered corresponds to the 80 metres standard British submarine. It is shown that under the ICD framework the multivariable control design of submarines can be solved, in an effective and clear manner, by applying classical ...

Experiments on incipient channelization of submarine fans

Journal of Hydraulic Research, 2002
Experiments on the formation of channelized submarine fans by the passage of successive turbidity currents are presented. Channels similar to subaerial rivers are found in many submarine fans. The inception of channels on submarine fans, which are essentially depositional environments, can be explained in terms of the lateral distribution of the rates ...

Global (latitudinal) variation in submarine channel sinuosity

Geology, 2012
Current classifications of submarine channels and fans link channel sinuosity to gradient, and in turn to sediment caliber, with end members being high-sinuosity, low-gradient, finegrained systems and low-sinuosity, high-gradient, coarse-grained systems.

Six-channel multiplex for submarine cable telegraphy

Electrical Engineering, 1958
THE RICHLY CULTIVATED CARIBBEAN area has imposed ever-increasing demands upon communication facilities to North America. To serve this market place and crossroads of transportation, the Western Union Telegraph Company operates three submarine telegraph cables between Havana, Cuba, and Key West, Fla., an average distance of 101 nautical miles ...

Flow processes and sedimentation in submarine channel bends

Marine and Petroleum Geology, 2007
Abstract Turbidity currents in sinuous submarine channels are an important mechanism for transporting terrestrial sediments to deep water, and their deposits are of increasing importance as hydrocarbon exploration targets. Despite this, the architecture and dynamics of submarine channel systems are not well understood.

Submarine volcanism in the Sicilian Channel revisited

Marine Geology
Highlights • New geophysical data and samples redefine submarine volcanism in Sicilian Channel. • Three dominant bands of volcanism are distinguished. • Ancient, eroded structures aligned at 120° are tied to faulted banks in the north. • Younger band of similarly aligned volcanism in the south is linked to grabens. •

Submarine channel curvature and migration distance : a study of Joshua Channel with implications for sinuous submarine channel geomorphology and deepwater reservoir connectivity

2020
The nature of plan-view migration in submarine channels is a subject of debate among researchers, and of significance to oil and gas investment in deepwater prospects. Early work has suggested that common features in fluvial channels such as downstream migration are rare or absent in deepwater reservoirs, and that relationships between geometric ...
