Research question(s):

Shelf-edge deltas are the one of the principal sources of clastic material into the deepwater. Consequently, identification and understanding of the sediment transport processes in operation at these locations is critical to deepwater hydrocarbon exploration. Physical processes that can deliver sediment to the deepwater from the shelf edge are diverse, but few detailed examples currently exist that examine how these processes vary in 3 dimensions (along strike as well as down dip) and how this strike-variability at the shelf edge impacts variability in deposits on the adjacent slope and basin floor.
