Characterisation of Submarine Acoustic Transmission Channels

1981
Some experimental results about an active characterisation of the submarine acoustic horizontal and middle range propagation are given. First simultaneous monochromatic signals are emitted which lead to the analysis of power and phase fluctuations. Then high — product BT signals are used to estimate the channel bitemporal response and the scattering ...

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 ...
