Geostrophic contour-following bottom currents involved in the deep thermohaline circulation of the world ocean appear to be the principal agents which control the shape of the continental rise and other sediment bodies. 
Oceanic Sediment Volumes and Continental Drift
The volume of sediment off the Atlantic Coast of the United States is at least six times as great as that off the Pacific Coast if the continent is drifting westward and has overrun large volumes of sediment on a former Benioff zone.
A sedimentary channel along Gibbs Fracture Zone
The depositional asymmetry associated with a channel along the fracture zone at 52°N in the Atlantic is explained by an eastward-flowing bottom current. This current, below 3000 m, is opposite to the
Morphology of the Northeastern Atlantic and Labrador Sea
Recent surveys by the US Naval Oceanographic Office have added greatly to the knowledge of the primary and secondary processes which have created the present morphology of the northeastern Atlantic
All core evidence supports the conclusion that abyssal plains are sites of graded-bed sequences deposited from turbidity flows. The deposits appear to be present-day equivalents of thin- to
The Faeroe—Iceland—Greenland Aseismic Ridge and the Western Boundary Undercurrent
The Miocene increase of bottom currents in the western North Atlantic is linked to subsidence, by thermal contraction of the cooling lithosphere, of the sills forming the aseismic ridge east and west

Suspended Matter in Deep Ocean Water
A nepheloid layer has been observed by optical means in the lower part of the water column on the continental slope and rise. By sampling it has been found to be a suspension of lutite, apparently in
Atlantic Ocean atlas of temperature and salinity profiles and data from the International Geophysical Year of 1957-1958
The cost of preparation and publication of this atlas was borne by a grant from the National Science Foundation, made in support of the International Geophysical Year Interdisciplinary Research
On the existence of bottom corrugations in the Blake‐Bahama Basin
Echo sounding records taken in the Blake-Bahama basin near 26°00′N, 76°10′W show crescents later than the main bottom reflection. The crescents are interpreted as diffraction arrivals from a
Bottom Sediments of the Atlantic Shelf and Slope off the Southern United States
The submarine geology of the South Atlantic continental shelf and slope of the United States has been described using data from bottom sediment samples collected aboard the Research Vessel T. N. Gill
Manganese Pavements on the Blake Plateau
Dredge samples and photographs from the Blake Plateau indicate that a layer of manganese oxide forms pavement that may be continuous over an area of about 5000 square kilometers, and the Gulf Stream probably maintains a very unusual environment that prohibits deposition of clastic sediment and permits accretion ofManganese pavements.
A moated knoll in the Canary Passage
A 100-fathoms high one-mile-wide elongate knoll approximately ten nautical miles long lies in 650 fms (1200 m) depth in the Canary Passage. The long axis is parallel to the axis of the passage. The
Seismic profiling with a hydroacoustic transducer and correlation receiver
Seismic profiles were made near 27°N, 73°W, on the outer ridge with a 2-kw broadband hydrostatic transducer as the sound source. This transducer is essentially an electrohydraulic positioning servo
Comparative nuclear effects of biomedical interest.
Selected physical and biological data bearing upon the environmental variations created by nuclear explosions are presented. Emphasis is placed upon the early consequences of exposure to blast,
