... occurring contemporaneously on nearby continental shelves. Changing shelf environments effectively control sediment bypassing of the shelf edge and thus modulate sediment accumulation in linked shelf, slope, and rise depocenters. In deep-water sections it is unlikely that large ecozone changes recorded...
