Note that Cores A 164-5 and A 164-6, which lie on either side of the Hudson Canyon on the continental rise, are entirely free of sand or silt, whereas most of the cores near the mouth of the canyon contain appreciable percentages of sand or silt. Cores A 164-63, -62 and -69 are associated with Hydrographer Canyon. (After Ericson, Ewing, Wollin and Heezen, 1961.)
