That erosion scar is arranged in a northwest-southeast direction, generates a relief of about m and has declivity of 8 degrees and reaches the edges of both canyons previously :// The focus site for this study lies near the intersection of the Carolina Rise and the Blake Ridge ().This area of the South Atlantic Bight has long been recognized as a major gas hydrate province within the US Exclusive Economic Zone (e.g., Markl et al., ; Tucholke et al., ; Paull and Dillon, ).Over most of the region, the top of the methane hydrate deposit probably lies at depths Inthe US Geological Survey (USGS) conducted a mapping program in the Gulf of Mexico.

This basin is somewhat like a miniature ocean in that it contains all of the main bathymetric provinces of an ocean along with a complicated coastal zone (Figure ).This chapter will consider the overall nature of the basin with emphasis on the sediments it :// Bacterial community structures were evaluated in oil samples using culture‐independent pyrosequencing, including oil mousses collected on sea surface and salt marshes during the Deepwater Horizon oil spill, and oil deposited in sediments adjacent to the wellhead 1 year after the spill.

The Levantine Basin, located at the southeastern corner of the Mediterranean Sea, is controlled by Nilotic supplies of sediments and nutrients, it is ultra-oligotrophic and is extremely sensitive to climatic changes (e.g., Almogi-Labin et al., ).The basin floor is directly supplied by a dense net of turbidite channels of the Nile Deep Sea Fan The Sedimentological analysis indicates that sediments most of the locations the sediments are very poorly to well sorted with mean size ranging from to φ.
