... 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 A unified and verifiable approach is outlined for the assessment of submarine sediment density flows (debris flows, high density and dilute turbidity currents) providing diagnostic criteria of their previous occurrence to inform forward-looking analyses. The assessment outlined...

... 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...

... accumulation rates are documented on Hueneme submarine fan in Santa Monica Basin (SMB). High-resolution seismic-reflection profiles across Ocean Drilling Program (ODP) borehole 1015 in the basin plain provide a well-dated chronostratigraphic record. Turbidity currents in Santa Monica Basin are sand-dominated...

.... Distinction is given to the different behavior of clay-rich and the more sandy flows. Introduction Submarine debris-flows, mudflows, rockslide, and turbidity currents are important mass wasting processes along the continental margin causing the transport of sediments into the deep sea. These submarine gravity...

.... In the final, abandonment stages of the life of a channel, the infill typically shifts towards silt and mud. 2.3 Levees Processes. Levees are the sediments deposited laterally to a channel by overbanking of the upper part of the flows. Due to the vertical concentration gradient in turbidity currents, the upper...

.... The abstract must contain conspicuous acknowledgment of where and by whom the paper was presented. Abstract The ocean floor, from the outer edge of a continental shelf to the abyssal depths, is subject to a range of fast sediment- charged bottom currents, such as turbidity currents, mud flows and debris flows...
