Modeling Of Selected Continental Slope Processes
نویسنده
چکیده
The objectives of this project are to: (1) Characterize the effect of spatial variations in deposition and erosion on the fluid flow, pore pressures and thus the stability of continental slope sediments. (2) Constrain the impact of individual turbidity currents on seafloor evolution. (3) Develop a technique for correlating stratigraphy complicated by spatial variations in sedimentation, erosion and post-depositional processes. (4) Assess the fidelity to which various seismic sources image stratigraphy.

Eddy generation and jet formation via dense water outflows across the Antarctic continental slope
Along various stretches of the Antarctic margins, dense Antarctic Bottom Water (AABW) escapes its formation sites and descends the continental slope. This export necessarily raises the isopycnals associated with lighter density classes over the continental slope, resulting in density surfaces that connect the near-freezing waters of the continental shelf to the much warmer CDW at mid-depth offs...
متن کاملConnecting Antarctic Cross-Slope Exchange with Southern Ocean Overturning
Previous idealized investigations of Southern Ocean overturning have omitted its connection with the Antarctic continental shelves, leaving the influence of shelf processes on Antarctic Bottom Water (AABW) export unconsidered. In particular, the contribution of mesoscale eddies to setting the stratification and overturning circulation in the Antarctic Circumpolar Current (ACC) is well establish...
متن کاملOcean processes at the Antarctic continental slope
The Antarctic continental shelves and slopes occupy relatively small areas, but, nevertheless, are important for global climate, biogeochemical cycling and ecosystem functioning. Processes of water mass transformation through sea ice formation/melting and ocean-atmosphere interaction are key to the formation of deep and bottom waters as well as determining the heat flux beneath ice shelves. Cli...
متن کاملForward Modeling of Stratigraphic Sequences at Continental Margins
The goal of the Stratigraphy project of the STRATAFORM program is to understand the creation of the preserved stratigraphic record on continental shelves and slopes as the product of physical processes acting with spatial and temporal heterogeneities. I am using numerical models to provide insight into the formation and preservation of stratigraphic sequences at margins. My goal is to obtain a ...
متن کاملSediment Formation in Nearshore Environments: Strength, Rheology, Microstructure, and Stability
Our goals are to understand how geotechnical and physical properties develop in marine sedimentary deposits on continental margins and how these properties influence sediment transport processes and the development of geomorphology. Our studies include predicting stability of sediment on the continental shelf and slope, providing input parameters for models of sediment transport and deformation...
