Concave profiles of submarine channels can be explained by an overall decrease in sediment discharge downstream as sediment is stripped from the upper parts of the turbidity currents and deposits in the upper parts of a fan, but other processes such as downstream fining may also play a role (Parker et al, in press). Despite the major advances. Monterey Canyon is one of the deepest submarine canyons on the west coast of the United States. The canyon head lies just offshore of Moss Landing on the Central California coast. From there, the main channel meanders over kilometers seaward to a depth of .
Deepest Point: 12, feet or 3, meters in the Monterey Bay Submarine Canyon, which is deeper than the Grand Canyon. Volume: 4, cubic miles or 7,,, olympic-sized swimming pools.

Some geologists have interpreted this depression as a valley of erosion cut by Salinas River when the land stood higher than at present and when the bottom of the bay was dry land. Prof. A. C. Lawson, however, has maintained that a similar submarine valley, in Carmel Bay south of Monterey, which is not quite in line with the present valley of. The Monterey Peninsula cities of Monterey, Pacific Grove and Carmel-by-the-Sea are represented on the Monterey County Board of Supervisors by Supervisor Mary Adams. The cities of Seaside, Sand City, Del Rey Oaks and Marina, which many locals also consider part of the greater Monterey Peninsula, are represented by Supervisor Jane Parker.

Hamlin. It is felt that the horseshoe meander unique to this Fan Valley is related to this same mechanism and to the intersection with the Ascension Fan Valley. A secondary channel was observed beneath the western levee (right-hand levee looking downstream) of the Upper Monterey Submarine Fan : Jr.
James Sherrill Hamlin. If the westward extending fan valley, entrenched on the Monterey submarine fan is included, the total length of the canyon is miles ( km). Its maximum wall height is 5, feet (1, m), and its maximum rim-to-rim width is miles (12 km).
It is similar in depth and width to Grand Canyon. North of Monterey Bay, there are eight small canyons called the Ascension Canyon system.
Some investigators have pointed to these eight canyons as being at one time part of the lower Monterey Canyon.
13 But, there should then be another fault between the mouth of Monterey Canyon and its downslope Size: KB. could be structurally or fault controlled, but rock structure and faults are responsible for only a small number of meanders.
Extensions from submarine canyons into submarine fans are called fan valleys. The channel of the Monterey fan valley has a horseshoe-shaped entrenched meander called the Shepard Meander (see Figure ).

(1) The large-leveed valley(s) of the upper fan produce wide (1 to 5 km) valley-floor deposits that are the coarsest on the fan and are deposited in meandering or braided, shallow channels within the general confines of the valley.
These coarse deposits grade laterally into finer grained and more regularly bedded levee sands and by: (1) The large-leveed valley(s) of the upper fan produce wide (1 to 5 km) valley-floor deposits that are the coarsest on the fan and are deposited in meandering or braided, shallow channels within the general confines of the valley.

Prather, Mark E. Deptuck, David Mohrig, Berend Van Hoorn, Russell B. Wynn. The Monterey submarine canyon, incised across the continental shelf in Monterey Bay, California, provides a record of the link between onshore tectonism, fluvial transport, and deep-marine : Andrea Fildani.
a depth of 3, m, Monterey Fan-Valley is joined by the lower submarine channels of Ascension Canyon. Monterey Canyon and its tributaries are generally characterized on the shelf and upper slope areas by "V"-shape cross-sections with steep walls and nar row floors.
OFR Cited by: Written By: Monterey Canyon, largest and deepest submarine canyon off the Pacific coast of North America. The canyon has three tributaries at its upper reaches in Monterey Bay, California: minor Soquel Canyon to the north, the main Monterey Canyon head aligned east-west off Moss Landing, and Carmel Canyon to the south.
The Zodiac Fan from western Alaska Granted that there has been little movement of the lower Monterey Submarine Canyon and Fan with respect to the upper part of the canyon, there are other bottom features on the Pacific Plate that indicate even more of a discrepancy.
Luminescence Dating of Submarine Canyons: Application to the Monterey Canyon, California C. Heerema Submarine canyons are major geomorphic features, transporting large quantities of sediments from land to the deep sea.
These sediments contain nutrients, enabling life in the deep sea and potentially forming hydrocarbon reservoirs. Monterey Canyon begins at Moss Landing, California, which is situated along the middle of the coast of Monterey Bay, and extends horizontally 95 mi ( km) under the Pacific Ocean where it terminates at the Monterey Canyon submarine fan, reaching depths of up to 3, m (11, ft) below surface level at its downstream mouth.
It is a part of the greater Monterey Bay Canyon System, which consists of. The upper Monterey Canyon is an active submarine system closely coupled with sand transport along the shoreline (Paull et al., ).
The sand has been ‘followed’ moving varying distances into the canyon on a semi-regular basis during gravity-flow events (Paull et al.,), Cited by: 9. Lake Corcoran.
Lake Corcoran (also known as Lake Clyde, after Clyde Wahrhaftig, an American geophysicist) is an ancient lake that covered the Central Valley of California. The lake existed in the valleys of the Sacramento River and the San Joaquin River. An alternate view presumes that the lake covered only the southern parts of the Central Valley.Hueneme and Dume submarine fans in Santa Monica Basin consist of sandy channel and muddy levee facies on the upper fan, lenticular sand sheets on the middle fan, and thinly bedded turbidite and.Upper Miocene Potter sands in the northern part of the Midway-Sunset field were analyzed extensively using detailed electric-log correlations.
