“…Broad shallow channels crossing the continental shelf are the Hudson Channel southeast of Long Island, Block Channel south of Rhode Island, and Great South Channel, southeast of Cape Cod. One deep channel (Northearst Channel) provides a deepwater entrance to the basins of the Gulf of Maine and is thought to be a river valley carved before the Pleistocene and subsequently modified by glacial erosion (Torphy and Zeigler, 1957;Uchupi, 1966a). The shallow channels are thought to be relict fluvial Pleistocene drainageways formed during lower stands of sea level in glacial stages.…”

L2 ATLANTIC CONTINENTAL SHE,LF AND SLOPE OF THE UNITED STATES water deposits of silt and clay likewise tend to be log normally distributed, though with a moderate sorting. These deposits are most similar in curve shape to gravity-settled clays from abyssal plains and sheltered bays. Poorly sorted mixtures of sand, gra'\,nel, silt, and clay from the• Gulf of Maine tend to be log normal in their distribution and to show a similarity to tills deposited on land. Polymodal mixtures of sand and gravel show a nonnormal steplike curve and probably reflect transport by saltation and suspension for the sand, and surfac'e creep or ice for the gravel. The size distribution curve of most of the silty sand on the upper continental slope and on the flanks of basins in the Gulf of Maine is skewed toward the coarse fraction to give an asymmetrical distribution of moderately sorted silt and clay in with fairly well sorted sand. This type sediment generally covers a transitional area between well-sorted log-normally distributed sand of the shelf and moderately sorted log-normally dis.tributed silty clays of deeper water areas; hence, it may be the result of two processes of sedimentation-deposition of sand by currents and pelagic deposition of silt and clay. Thorough biogenic reworking has mixed the two components.
