Simplified method of deep-tow seismic profiling Simplified method of deep-tow seismic profiling

To improve resolution of seismic-reflection profiles in continental slope water depths of 900 to 1500 m, a single hydrophone was towed about 150 m off the bottom to receive reflected signals from a surface-towed sparker sound source. That deep-towed hydrophone data show that valleys which appear V-shaped in records from a surface-towed hydrophone are flat-bottomed, and that subbottom...

Morphology and processes associated with the accumulation of the fine-grained sediment deposit on the southern New England shelf 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...

Composition and origin of phosphorite deposits of the Blake Plateau Composition and origin of phosphorite deposits of the Blake Plateau

An area of about 22 000 km2 on the N Blake Plateau contains an estimated 2 billion tonnes of phosphorite concretions, and about 1.2 billion tonnes of mixed ferromanganese-phosphorite pavement. The phosphorite consists primarily of carbonate-fluorapatite, some calcite, minor quartz and other minerals. Drilling and other evidence show that the phosphorite is a lag derived from Miocene...

Diatoms and stratigraphically significant silicoflagellates from the Atlantic Margin Coring Project and other Atlantic margin sites Diatoms and stratigraphically significant silicoflagellates from the Atlantic Margin Coring Project and other Atlantic margin sites

In 1976, 19 sites were cored along the U.S. Atlantic Continental Shelf and Slope by the Oceanographic Branch of the U.S. Geological Survey aboard the Glomar Conception. Only 6 sites contained siliceous microfossil assemblages of sufficient quantity and quality for biostratigraphic study. Two of the sites, AMCOR (Atlantic Margin Coring Project) 6002 and AMCOR 6011, contained good Miocene

Evolution of the continental margin of southern Spain and the Alboran Sea Evolution of the continental margin of southern Spain and the Alboran Sea

Seismic reflection profiles and magnetic intensity measurements were collected across the southern continental margin of Spain and the Alboran basin between Spain and Africa. Correlation of the distinct seismic stratigraphy observed in the profiles to stratigraphic information obtained from cores at Deep Sea Drilling Project site 121 allows effective dating of tectonic events. The...

Stratigraphy and depositional environments of Baltimore Canyon Trough Stratigraphy and depositional environments of Baltimore Canyon Trough

The Baltimore Canyon Trough, lying offshore from the United States Middle Atlantic States, contains a thickness of at least 14 km of marine and nonmarine sedimentary rocks. One deep offshore stratigraphic test (COST B-2 well), several wells on the coastal plain, 18 shallow core holes (Deep Sea Drilling Project, Atlantic Slope Project, and Atlantic Margin Coring Project) on the...

Reply to discussion by Michael A. Collins, "Fresh ground water stored in aquifers under the continental shelf: implications from a deep test, Nantucket Island, Massachusetts" Reply to discussion by Michael A. Collins, "Fresh ground water stored in aquifers under the continental shelf: implications from a deep test, Nantucket Island, Massachusetts"

We appreciate the comments made in the discussion by Michael A. Collins, regarding our paper about the anomalously low salinity of water underlying Nantucket Island. However, we feel that in his effort to justify the mathematical approach for solving salt water intrusion problems, he has overlooked several of the major points in this paper. We will try to amplify these points to

Availability of single channel seismic refraction profiles collected over U.S. Atlantic continental slope and rise north of Cape Hatteras - USGS cruises FAY 20 and FAY 21 - August/September 1976 Availability of single channel seismic refraction profiles collected over U.S. Atlantic continental slope and rise north of Cape Hatteras - USGS cruises FAY 20 and FAY 21 - August/September 1976

A series of single channel seismic reflection profiles were collected by the U.S. Geological Survey aboard the R.V. FAY from August 10, 1976 through September 7, 1976 during cruises FAY 20 and FAY 21. The chief scientist was, Dr. Kim D. Klitgord, U.S. Geological Survey, Woods Hole, MA 02543. The profiles are located on the slope and rise between Cape Hatteras and the New England...

Geology of the offshore Southeast Georgia Embayment, U.S. Atlantic continental margin, based on multichannel seismic reflection profiles Geology of the offshore Southeast Georgia Embayment, U.S. Atlantic continental margin, based on multichannel seismic reflection profiles

A geologic interpretation of the offshore Southeast Georgia Embayment is based on an 1,100-km multichannel seismic reflection survey conducted jointly by the University of Texas Marine Science Institute and the U.S. Geological Survey. The Southeast Georgia Embayment consists of a wedge of Cretaceous and Cenozoic sedimentary rocks that thins from 5 to 8 km beneath the Blake Plateau to...
