N.E. King, James C. Savage
1984, Journal of Geophysical Research B: Solid Earth (89) 2471-2477
The Tehachapi trilateration network spans the intersection of the San Andreas and Garlock faults in southern California in the “Big Bend” region of the San Andreas fault. Analysis of data from 1973–1983 shows strain differences between the northwest and southeast regions of the network and slip at...
Storm-generated variations in nearshore beach topography
Harry F. Lins
1984, Marine Geology (62) 13-29
A series of nearshore beach profile measurements from the Outer Banks of North Carolina spanning a four-month period have been examined for temporal variations in nearshore topography. Principal component analysis of the profile data indicates that most of the variation in nearshore topography occurs in four principal modes, two quasiseasonal...

Michael R. Simpson, Lowell F. W. Duell Jr.
1984, Groundwater Monitoring & Remediation (4) 155-163
As part of a plant survivability and ground water study in Owens Valley, California, semipermanent installations are used to measure continuous range‐land evapotranspiration in the valley's phreatophyte community. A proposed mobile installation also has been designed. The semipermanent micrometeoro‐logical station collects continuous data for solution of the Bowen ratio/energy budget...
Proceedings of a workshop on fish habitat suitability index models
James W. Terrell
1984, Biological Report (85)
One of the habitat-based methodologies for impact assessment currently in use by the U.S. Fish and Wildlife Service is the Habitat Evaluation Procedures (HEP) (U.S. Fish and Wildlife Service 1980). HEP is based on the assumption that the quality of an area as wildlife habitat at a specified target year...
A workshop model simulating fate and effect of drilling muds and cuttings on benthic communities
Gregor T. Auble, Austin K. Andrews, David B. Hamilton, James E. Roelle, Thomas G. Shoemaker
1984, Report
Oil and gas exploration and production at marine sites has generated concern over potential environmental impacts resulting from the discharge of spent drilling muds and cuttings. This concern has led to a broad array of publicly and privately sponsored research. This report described a cooperative modeling effort designed...
A comparative ground response study near Los Angeles using recordings of Nevada nuclear tests and the 1971 San Fernando earthquake
A. M. Rogers, Roger D. Borcherdt, P. A. Covington, D. M. Perkins
1984, Bulletin of the Seismological Society of America (74) 1925-1949
A comparative ground response study at sites in the Los Angeles region is based on the extensive strong-motion data set recorded in the 1971 San Fernando earthquake and 159 three-component recordings of distant nuclear tests in Nevada. Amplitude spectral ratios computed for the nuclear...

J. E. Hazel, Laurel M. Bybell, Lucy E. Edwards, G. D. Jones, L. W. Ward
1984, GSA Bulletin (95) 1040-1044
The biostratigraphic and chronostratigraphic position of the Comfort Member of the Castle Hayne Formation has been the subject of much debate. At the Martin-Marietta Quarry at Castle Hayne, New Hanover County, North Carolina, the planktic foraminifers indicate an assignment within an interval of the uppermost Turborotalia frontosa Zone to the Turborotalia pomeroli Zone. The...
Oxygen isotope ranking of late Eocene and Oligocene planktonic foraminifers: Implications for Oligocene sea-surface temperatures and global ice-volume
R.Z. Poore, R.K. Matthews
1984, Marine Micropaleontology (9) 111-134
Oxygen isotope analyses of late Eocene and Oligocene planktonic foraminifers from low and middle latitude sites in the Atlantic Basin show that different species from the same samples can yield significantly different isotopic values. The range of isotopic values observed between species is greatest at low-latitudes and declines poleward. Many...
National Cartographic Information Center
Water Resources Division, U.S. Geological Survey
1984, Report
The National Cartographic Information Center (NCIC) exists to help you find maps of all kinds and much of the data and materials used to compile and to print them. NCIC collects, sorts and describes all types of cartographic information from Federal, State and local government agencies and, where possible, from...
Determination of hydraulic conductivity in three dimensions and its relation to dispersivity: Chapter D in Ground-water contamination by crude oil at the Bemidji, Minnesota, research site; US Geological Survey Toxic Waste--ground-water contamination study
1984, Water-Resources Investigations Report 84-4188-D
Recent investigations suggest that dispersion in aquifers is scale dependent and a function of the heterogeneity of aquifer materials. Theoretical stochastic studies indicate that determining hydraulic-conductivity variability in three dimensions is important in analyzing the dispersion process. Even though field methods are available to approximate hydraulic conductivity in three dimensions,...
Geologic evolution, sedimentation, and paleoenvironments of the Angola Basin and adjacent Walvis Ridge: Synthesis of results of Deep Sea Drilling Project Leg 75
Walter E. Dean, W.W. Hay, Jean-Claude Sibuet
1984, Initial Reports of the D.S.D.P. (75) 509-544
The section recovered at Site 530 (Holes 53OA and 530B) consists of eight sedimentary units and one basalt unit. The composition of the basalt recovered in Hole 53OA is distinct from typical mid-ocean ridge basalts (MORBs) but is similar to that of Hawaiian tholeiites and basalt from the central part...
Remote sensing and geophysical investigations of glacial buried valleys in northeastern Kansas
Jane E. Denne, Harold L. Yarger, P. A. Macfarlane, Ralph W. Knapp, Marios A. Sophocleous, James R. Lucas, Don W. Steeples
1984, Groundwater (22) 56-65
Aquifers found in glacial buried valleys are a major source of good-quality ground water in northeastern Kansas. The extent and character of many of these deposits are not precisely known, so a detailed study of the buried valleys was undertaken. Test drilling, Landsat imagery, shallow-earth temperature...

Statistical summaries of streamflow data at 335 streamgaging sites are presented in this two volume report to aid in appraising the hydrology of river basins in Oregon. Records for 31 gaging stations were compiled into separate periods owing to changes in regulation during the period of data collection. The periods...

Availability of water from the alluvial aquifer in part of the Green River Valley, King County, Washington
W. E. Lum II, R. C. Alvord, B. W. Drost
1984, Water-Resources Investigations Report 83-4178
The Muckleshoot Indian Tribe plans (1982) to build a fish hatchery in part of a 1.56-square-mile area in the Green River valley, Washington, and use groundwater to operate it. Groundwater data were collected in the area and used in a U.S. Geological Survey two-dimensional groundwater-flow model calibrated to simulate the...
The quality of ground water in the principal aquifers of northeastern-north central Washington
J.C. Ebbert
1984, Water-Resources Investigations Report 83-4102
In 1979 the quality of ground water in major aquifers in northeastern-north central Washington State was assessed in terms of inorganic-chemical, trace-metal, and fecal-coliform concentrations. For the Spokane Valley aquifer some organic-chemical data were also included. Results of this assessment indicate that the ground water in the region is generally...

1984, Conference Paper, Marine birds: Their feeding ecology and commercial fisheries relationships
Food brought to nestling Rhinoceros Auklets (Cerorhinca monocerata) was sampled by applying tape or cloth muzzles to the chicks and collecting the uningested food from the burrow daily. Limited data were also gathered for Tufted and Horned puffins (Fratercula cirrhata and F. corniculata). Auklet chicks received an average of 34.1...

Schreiber David L., editor(s)
1984, Conference Paper
The South Fork Cumberland River begins in Tennessee at the confluence of the New River and Clear Fork. Strip mining for coal in the New River basin has been ongoing for decades with little reclamation prior to 1977. Water-quality data show that suspended-sediment and dissolved-constituent loads from the New River...
