Abstract

Gillian Apps, Alex Bump, Tim Dooley, and Andy Pulham
When people consider the Gulf of Mexico, the plate tectonic context is accounted for; in terms of its impact on hinterland uplift, sediment supply to the shelf and slope, and the gravity and salt tectonics. It is only recently that we have begun to consider the implications of super-regional effects of multi-million year mantle upwelling and down welling, on the surface topography, sediment flux to the coast and shelf margin. Here, we explore the implications for the evolution of the deep water, in terms of sediment flux & loading, gravity tectonics and salt dynamics.
