Water Depths and Topografhy of Bottom
The water depths range from about 66 m in the southwest up to 308 m in the northeast, with an average slope of approximately 0.4% (0.25 grades) to the east-northeast. The relief of the seabed is generally irregular and includes frequent scarps related with faulting and erosion.Geology
The seabed in general is composed mainly of very softclays
Clay is a type of fine-grained natural soil material containing clay minerals (hydrous aluminium phyllosilicates, e.g. kaolin, Al2 Si2 O5( OH)4).
Clays develop plasticity when wet, due to a molecular film of water surrounding the clay par ...
. The geologic features in this area include normal faults with northwest-southeast orientation, a system of exposed and buried reefs that cross the area from the
northwest toward the southeast, gas pockets trapped in faults and shallow strata at different levels of depth, paleo-channels, abrupt erosional slopes and scarps associated with submarine debris flows and faulting. Several side scan sonar targets are interpreted as scattered small debris.Deiros, D. Sackett, D.
