We delineate the escarpment into four geomorphic provinces based on submarine canyon density and morphology, as well as pronounced geomorphological differences...

Petrophysical and geological analyses were conducted to determine the distribution of sand bodies in thirty study wells drilled across from Alaminos Canyon through Keathley Canyon to Walker Ridge (W-E). A geomechanical analysis was conducted to determine the variation of rock mechanical...

... Abstract This paper describes the measurement and modeling of turbidity currents (TC) in the Congo Canyon and the application of that data to design of a telecommunications cable. There are few direct measurements of TCs largely because the measurement instruments are often damaged. Indeed...

... Abstract Turbidity currents are known to occur frequently in the Congo Canyon which is within a few kilometers of blocks being explored and developed by oil companies. Given the potential strength of turbidity currents, design engineers are keen to know their strength, frequency, and vertical...

... Introduction The Congo Canyon, situated at the mouth of the Congo River of the west coast of Africa, is one of the largest submarine canyons in the world (Figs. 1A, 1B; Shepard, 1973). This canyon is unique among the valleys of the ocean floor in that it extends 20 miles into the Congo River...

In March of 2007, the Loop Current advanced rapidly north of 28°00 N, engulfing most of Lloyd Ridge and entering into southern DeSoto Canyon...
