Bottom currents at about m depth in and around a submarine valley on the continental slope of the northern South China Sea were studied by a month long experiment from July to September The observations reveal that bottom currents are strongly influenced by the topography, being along valley axis or : Lunyu Wu, Xuejun Xiong, Xiaolong Li, Maochong Shi, Yongqing Guo, Liang Chen.

Currents in submarine canyons F. SHEPARD,*N. MARSHALL* and P. McLouGHLIN* (Received24 October ; in revisedform 1 April ; accepted 1 April ) Abstract--Earlier work indicated that currents move alternately up and down the floors of submarine canyons with greater average speeds Cited by: In another example of canyons, the Monterey Submarine Canyon begins at Moss Landing, California, the middle of the Monterey Bay, and extends 95 miles ( km) into the Pacific Ocean where it terminates at the Monterey Canyon submarine fan, reaching depths.

Most of the internal tide energy entering the canyon is generated to the south, on Sur Slope and at the head of Carmel Canyon. The internal tide is topographically steered around the large canyon by: The submarine canyon example of the BbC demonstrates that activity in submarine canyons along convergent margins, and their role in transporting large quantities of sediment and associated pollutants, nutrients, and organic carbon to the deep seafloor during sea-level highstands, is controlled by several local variables, including bottom Cited by:   On the basis of newly collected multibeam bathymetric data, chirp profiles and existing seismic data, we presented a detailed morphological interpretation of a series of slope-confined canyons in water depths of – m in the Baiyun deep-water area, northern margin of the South China Sea.

Some of the more intriguing scientific techniques employed by Paull and his team to provide a. Although such weak flow speed is comparable to deep-sea turbidity currents on levees adjacent to channels (e.g., Khripounoff et al., ), it is almost one order of magnitude slower than those previously measured in the main body of submarine turbidity currents from locations in the axis of canyons such as the Congo Canyon (Azpiroz-Zabala et Cited by: Monterey Canyon system, marks the transition zone from the wide continental shelf in the north to the narrower shelf in the south.

Carmel Bay is protected in the waters between Point Pinos and Point Lobos. The Carmel Bay is bisected by Carmel Canyon, which extends southwest from the Carmel River until it joins the submarine canyon in Monterey Bay.

upwelling. In the upper and southern bay, cross-shelf exchange is due to cold-water bores that propagate out of the Monterey Submarine Canyon.

The source of variability in the arrival of these bores on the mid and inner shelf is likely due to complex surface-internal tidal interactions that can lead to cold waters cresting the canyon or shelf edge.

The semidiurnal internal tide sets up a partly standing wave within the canyon due to reflection at the canyon head, dissipating all of its energy within the canyon.

Dissipation in the near-bottom is associated with the diurnal trapped tide, while midwater isopycnal shear and strain is associated with the semidiurnal : Amy Waterhouse. Inside the submarine canyons, this kind of habitat is also isolated from deep open water, and hence could enhance speciation of organisms that inhabit their near-bottom layers.

Submarine canyons act as a trap for particulate matter in its movement from the sea shelf to deeper by: Scientists and technical staff within the USGS Coastal and Marine Geology Program study coastal and ocean resources from shorelines and estuaries to the continental shelf and deep sea, providing expertise, tools, products, and data that address and inform a broad array of resource challenges facing our Nation.

shelf. In this study, our interest was primarily with the topography of this center shelf—the site location of the three replication (WCB) and the "production model" (Redondo Canyon) reefs.

The shelf is generally characterized as being "smooth" and gently sloping seaward to approximately 50 fathoms (Figure 1).Turbidity currents may be common in basinal settings. Submarine canyons are unique because the shelf-slope break does not control processes within the canyon; both tidal currents and mass flows operate within canyons (see Chapter 4).
