Submarine canyons are deep incisions observed along most of the world's continental margins. Their topographic relief is as dramatic as that of any canyon or river valley on land but is hidden beneath the surface of the ocean. Our knowledge of canyons has therefore come primarily from remote sensing and sampling, and has involved contributions from ...

Deep Sea Research and Oceanographic Abstracts, 1974
Abstract Earlier work indicated that currents move alternately up and down the floors of submarine canyons with greater average speeds and longer duration downcanyon. Now we find there are roughly synchronous movements up to at least 34 m above the canyon floors.

Submarine Canyons in the Bathtub
Journal of Sedimentary Research, 2005Abstract Submarine megafans and their associated canyons have long attracted the attention of a large community in the earth sciences because they record the history of past erosional processes. As such, their morphology and sedimentary infill may be of use to unravel past climatic and tectonic evolution.

The submarine canyons of Kamchatka
Marine Geology, 1984Abstract A system of large submarine canyons on the continental slope off the Kamchatka Peninsula has been studied. These are the Kamachatsky, Storozh, Tyushevsky, Olga, Kronotsky, Zhupanovsky and Avachinsky canyons and they are generally controlled by fault zones and cut the Pre-Miocene basement structural elements in the cross-strike direction ...

The characteristics of the Cayar Submarine Canyon off the coast of Senegal suggest that its evolution was controlled by submarine processes. This well-delineated, hitherto-unsurveyed canyon originates near the shoreline (10 to 20 m deep) on the upcurrent side of the Cape Verde peninsula and extends downslope to the oceanic basin.

ABSTRACT In May, 1957, a brief survey of the Congo Submarine Canyon was conducted from the Research Vessel VEMA. The canyon was found on the continental slope near the seaward limit of earlier surveys and traced to the west for 150 miles.

Submarine canyon: A brief review
2023Earth's surface configuration is in constant change due to geomorphic processes in operation. These processes are responsible for initiating several features such as channels, drainage basins, incised valleys, and submarine canyons. The understanding of these features is paramount for an accurate assessment of biological, environmental and geologic ...

An Hypothesis of Submarine Canyons
Geological Magazine, 1940The publication by the Geological Society of America of that momentous work by the late A. C. Veatch and P. A. Smith (1939) with its beautifully executed charts, following closely Douglas Johnson's stimulating contribution on the subject (1938), again focuses attention on those stupendous erosion-features—the “Submarine Canyons”.

Turbulence measurements in a submarine canyon
Continental Shelf Research, 1985Abstract Profiles of velocity turbulence in Monterey Canyon, made with a recently developed expendable probe, show the existence of a very turbulent bottom boundary layer. The turbulent flow is up to 170 m thick and has peak microscale shears of 1 m s −1 per meter.
