“…Here the coastline is twisted and interrupted by rocky headlands; hence, offs,hore wave patterns are more likely to be refracted by the coast and by an uneven s.ea floor. Zeigler and Ronne (1957) and Zeigler, Tuttle, Giese, and Tasha (1964) have shown a series of discontinuous bars offshore on outer Gape Cod para.Ilel to this straight stretch of coast. Much of the shaHow current-winnowed part of the sea floor off southern New England is in areas where glacial debris has been deposited as moraines and outwash in sufficient amounts to provide an ample supply of sediment for tractive cur-rents to heap it into sand shoals.…”

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.
