Long-term observations of bottom conditions and sediment movement on the Atlantic continental shelf; time-lapse photography from instrumented tripod
An instrument system that measures bottom current, temperature, light transmission, and pressure, and that photographs the bottom at 2- to 6-hour intervals has been developed to study sediment transport on the Atlantic Continental Shelf. Instruments have been deployed extensively along the United States East Coast Continental Shelf for periods of from 2 to 6 months to study the frequency, directio

Physical oceanography of continental shelves
Knowledge of the physical oceanography of continental shelves has increased tremendously in recent years, primarily as a result of new current and hydrographic measurements made in locations where no comparable measurements existed previously. In general, observations from geographically distinct continental shelves have shown that the nature of the flow may vary considerably from region to region

The Sea Data 651-4 data logger
This paper describes a digital data logger used as the primary controller and data collection device for the U.S. Geological Survey Sediment Monitoring Tripod Program. The tripods are deployed at sea in water depths up to 100 m for periods of 3 to 6 months. The system measures bottom current speed and direction, pressure, temperature, light transmission, and photographs the bottom. This report is

Morphology and processes associated with the accumulation of the fine-grained sediment deposit on the southern New England shelf
A 13,000 km2 area of the southern New England Continental Shelf which is covered by anomalously fine-grained sediment has been surveyed by means of high-resolution, seismic-reflection and side-scan sonar techniques to map its morphology and structure, and a near-bottom instrument system contributed to understanding present activity of the deposit. Seismic-reflection profiles show that the fine-gra

Semidiurnal bottom pressure and tidal currents on Georges Bank and in the Mid-Atlantic Bight
Observations of the semidiurnal (M2) tidal current, bottom pressure, and coastal sea level from Nova Scotia to Cape May, New Jersey) show that: 1) the surface pressure at the edge of the Continental Shelf in the study area has a relatively uniform amplitude (40 cm) and phase (12 hr Greenwich); 2) in the Mid-Atlantic Bight, the semidiurnal M2 tide is co-oscillating, and the onshore M2 tidal current

Long-term observations of bottom current and bottom sediment movement on the mid-Atlantic continental shelf
Long-term in situ observations made at three locations on the mid-Atlantic continental shelf during 1975–1976 clearly show intermittent movement of bottom sediment caused by currents, waves, and other forcing mechanisms. In winter, storm-associated bottom currents greater than 30 cm s−1 resuspended and transported sediments. Net water particle excursions during storms were about 20–30 km longshelf

An instrument system for long-term sediment transport studies on the continental shelf
A bottom-mounted instrument system has been designed and built to monitor processes of bottom sediment movement on the continental shelf. The system measures bottom current speed and direction, pressure, temperature, and light transmission and photographs the bottom. The system can be deployed for periods of 2–6 months to monitor intermitent processes of sediment movement such as storms and to ass

Summary report of the sediments, structural framework, petroleum potential, and environmental conditions of the United States Mid-Atlantic continental margin in area of proposed Oil & Gas Lease Sale No. 59
This report has been compiled to update and summarize the geological information concerning the area of the Atlantic continental margin off the U.S. Mid-Atlantic proposed for Oil and Gas Lease Sale No. 59 (fig. 1). The region of interest lies between 35° and 41° N and 70.5° and 76° W. The north-south dimension is about 660 km (356 nautical miles, 410 statute miles) and the maximum east-west dimens
