Seismic stratigraphic characteristics of upper Louisiana continental slope: an area east of Green Canyon Seismic stratigraphic characteristics of upper Louisiana continental slope: an area east of Green Canyon

A high-resolution seismic reflection survey was conducted in a small area of the upper Louisiana Continental Slope known as Green Canyon Area. This area includes tracts 427, 428, 471, 472, 515, and 516, that will be offered for sale in March 1982 as part of Lease Sale 67. The sea floor of this region is, slightly hummocky and is underlain by salt diapirs that are mantled by early...

Road log and documentary photographs for 15 significant biostratigraphic sites in Miocene-Pliocene limestone, Kingshill Seaway, St. Croix, U.S. Virgin Islands Road log and documentary photographs for 15 significant biostratigraphic sites in Miocene-Pliocene limestone, Kingshill Seaway, St. Croix, U.S. Virgin Islands

Detailed examination of planktonic Foraminifera from the type section of the Miocene Kingshill Limestone and from 14 other Miocene and lower Pliocene limestone exposures in the Kingshill Seaway of St. Croix ((at 17°44' N., long 64° 46' W.; fig. 1) has led to the first publication of an in-depth biostratigraphic investigation of this area with application of the most up-to-date zonation...

Geochemical evidence for modern sediment accumulation on the continental shelf off southern New England Geochemical evidence for modern sediment accumulation on the continental shelf off southern New England

An area of fine-grained sediment approximately 170 km x 74 km in size, located in water depths between 60 m and 150 m, south of Martha's Vineyard, Mass., is a site of modern sediment deposition. The 14C ages systematically increase with sediment depth from about 1,300 years B.P. at the surface to 8,000-10,000 years B.P. at the depth of maximum core penetration. The old age for the...

East Pacific rise at 21°N: the volcanic, tectonic, and hydrothermal processes of the central axis East Pacific rise at 21°N: the volcanic, tectonic, and hydrothermal processes of the central axis

Photographs obtained by the ANGUS survey system at 21°N reveal many similarities to the geological processes delineated at other spreading centers and in particular those observed in the Galapagos Rift at 86°W. The region of recent volcanism is restricted to a narrow zone (Zone 1) approximately 1 km wide. This suggests that the width of the magma chamber feeding these flows is also...

Sidescan-sonar data collected during May 1978 from the southern New England continental shelf Sidescan-sonar data collected during May 1978 from the southern New England continental shelf

Sidescan-sonar data were collected aboard R/V WESTWARD (Cruise W-39-4) during May 1978 by the U.S. Geological Survey using an Ocean Research Equipment System. Navigation in the study area was by Loran C. The 368 kilometers of survey were conducted in Block Island Sound, in Rhode Island Sound, and over the mid-Continental Shelf south of Block Island and Martha's Vineyard. Although the...

Data file: the 1976 Atlantic Margin Coring (AMCOR) Project of the U.S. Geological Survey Data file: the 1976 Atlantic Margin Coring (AMCOR) Project of the U.S. Geological Survey

In 1976, the U.S. Geological Survey conducted the Atlantic Margin Coring Project (AMCOR) to obtain information on stratigraphy, hydrology and water chemistry, mineral resources other than petroleum hydrocarbons, and geotechnical engineering properties at sites widely distributed along the Continental Shelf and Slope of the Eastern United States (Hathaway and others, 1976, 1979). This...

210Pb method for estimating the rate of carbonate sand sedimentation 210Pb method for estimating the rate of carbonate sand sedimentation

The plot of 210Pb activity against depth in carbonate sands on the Virgin Island Bank is a negative asymmetric hyperbolic curve. As depth increases, an initial rapid decrease in 210Pb activity caused by the decay of unsupported 210Pb and 226Ra is followed by increasing activity as a result of 210Pb achieving equilibrium with in growing 230Th. As this curve is time dependent, an estimate...
