Morphology of Hudson Canyon and Hudson Apron

Abstract

Hudson Canyon is the most prominent submarine canyon on the U,S. east coast, and it lies just north of Hudson Apron, an extensive depositional region on the continental slope that is unusually unstructured (stable') compared to the slope along the remainder of the margin. With funding from this grant, we processed bathymetric and backscatter data from an existing SeaBeam 2112 multibeam survey of these two provinces and made a preliminary analysis of the results. Hudson Canyon exhibits a wide range of morphological features which, to first order, can be related to lithology of the seafloor, the behavior of turbid down-canyon flows in response to regional seafloor gradient, and possibly the presence of gas hydrates beneath the continental rise. Hudson Apron, while regionally stable, shows small-scale indications of incipient slope failure.
