The gravity field of the U.S. Atlantic continental margin
John A. Grow, C.O. Bowin, Deborah R. Hutchinson
1979, Tectonophysics (59) 27-52
Approximately 39,000 km of marine gravity data collected during 1975 and 1976 have been integrated with U.S. Navy and other available data over the U.S. Atlantic continental margin between Florida and Maine to obtain a 10 mgal contour free-air gravity anomaly map. A maximum typically ranging from 0 to +70...
Seismic refraction study of the continental edge off the eastern United States
R. E. Sheridan, J. A. Grow, John C. Behrendt, K.C. Bayer
1979, Tectonophysics (59) 1-26
Three long, strike-parallel, seismic-refraction profiles were made on the continental shelf edge, slope and upper rise off New Jersey during 1975. The shelf edge line lies along the axis of the East Coast Magnetic Anomaly (ECMA), while the continental rise line lies 80 km seaward of the shelf edge. Below...
Anomalous topography on the continental shelf around Hudson Canyon
H.J. Knebel
1979, Marine Geology (33) 67-75
Recent seismic-reflection data show that the topography on the Continental Shelf around Hudson Canyon is composed of a series of depressions having variable spacings (< 100 m to 2 km), depths (1–10 m), outlines, and bottom configurations that give the sea floor an anomalous “jagged” appearance in profile. The acoustic...
Effects of oil transferred from incubating gulls to their eggs
Kirk A. King, C.A. LeFever
1979, Marine Pollution Bulletin (10) 319-321
No. 2 fuel oil, or water, was applied to the breast feathers of incubating laughing gulls trapped at their nest site on an island colony in Texas. Gulls were released after treatment and allowed to incubate their eggs for 5 days. Oil was transferred from the feathers of incubating adults...
Clay mineralogy, fine-grained sediment dispersal, and inferred current patterns, lower Cook Inlet and Kodiak shelf, Alaska
James R. Hein, Arnold H. Bouma, Monty A. Hampton, Ross C. Robin
1979, Sedimentary Geology (24) 291-306
Because lower Cook Inlet and Kodiak shelf are being explored and developed for their petroleum resources, it is essential for environmental reasons to understand the sediment dispersal routes and current patterns. The Susitna River flows into upper Cook Inlet and is the source of clay minerals in Holocene deposits found...
Relationship between physical condition of the carbonate fraction and sediment environments: Northern Puerto Rico shelf
O. H. Pilkey, E.I. Fierman, James V. A. Trumbull
1979, Sedimentary Geology (24) 283-290
Each of three sediment types recognizable on the northern Puerto Rico shelf and beaches is characterized by calcareous material in different physical condition. Dark terrigenous sand is accumulating at a relatively rapid rate and has a carbonate fraction containing fresh-appearing angular particles. The pure-carbonate skeletal-sand sediment type has a much...
Research in the United States relative to geochemistry and health
W.L. Petrie, H.L. Cannon
1979, Physics and Chemistry of the Earth (11) 829-847
Increasing concern regarding the effects of the geochemical environment on health in the United States has fostered research studies in a number of universities and government agencies. The necessity to evaluate the effects of natural and man-made elemental excesses in the environment on health requires the establishment of requirements and...
The determination of lead in 13 USGS standard rocks
P. J. Aruscavage, E.Y. Campbell
1979, Talanta (26) 1052-1054
Lead was determined in 13 U.S. Geological Survey standard rocks by graphite furnace atomization and atomic-absorption spectrometry after extraction of lead with diethylammonium diethyldithiocarbamic acid. An analysis of variance of the results obtained from a random sampling of three different bottles of each standard rock showed no heterogeneity among bottles,...

Maps showing late Pleistocene and Holocene evolution of the South Texas continental shelf
Carroll A. Pyle, Henry L. Berryhill Jr., Anita R. Trippet
1979, Miscellaneous Field Studies Map 1134
Interpretation of acoustical profiles has provided insight into the late Quaternary geologic history of the Continental Shelf off South Texas. (See the geographic index map on sheet 1 for location of the area studied.) The profiles reveal the interplay of tectonism, sedimentation, and cyclic fluctuations of sea level in the...
Results of Laboratory Tests on Surficial Sediments from the Upper Continental Slope Northern Gulf of Mexico
James S. Booth
1979, Open-File Report 79-579
The purpose of this report is to present the results of geotechnical, textural, and chemical tests performed on samples from the upper Continental Slope, northern Gulf of Mexico.The samples were collected by a piston corer up to 12 m (40 ft.} in length with a head weight of 908 kg...

Impact of flow regulation and powerplant effluents on the flow and temperature regimes of the Chattahoochee River— Atlanta to Whitesburg, Georgia
Robert E. Faye, Harvey E. Jobson, Larry F. Land
1979, Professional Paper 1108
A calibrated and verified transient flow-temperature model was used to evaluate the effects of flow regulation and powerplant loadings on the natural temperature regime of the Chattahoochee River in northeast Georgia. Estimates were made of both instantaneous and average natural temperatures in the river during an 8-day period in August...

R. C. Severson, L. P. Gough
1979, Professional Paper 1083
In order to assess the contribution to plants and soils of certain elements emitted by phosphate processing, we sampled sagebrush, grasses, and A- and C-horizon soils along upwind and downwind transects at Pocatello and Soda Springs, Idaho. Analyses for 70 elements in plants showed that, statistically, the concentration of 7...
