Marine geotechnical data for North Pacific sediments
Adrian F. Richards
1978, Open-File Report 78-231
Geotechnical data from the published and unpublished literature are compiled in SI units and tabulated in a standardized format. Eight data sets are presented from a geographic area approximately bounded by 5° and 32° north latitude and 120° and 170° west longitude. The data exist in machine-readable form in the...
Preliminary catalog of earthquakes in southern California, October 1976-September 1977
Gary S. Fuis, J.H. Whitcomb, C.E. Johnson, D.J. Jenkins, K.J. Ritcher, A.C. Blanchard, S.A. Fischer, B.A. Reed
1978, Open-File Report 78-672
There has been a continuing demand on the part of many persons, institutions, commercial companies, government agencies, and so forth for up-to-date maps and tables of earthquakes in southern California. Unfortunately, final catalogs of earthquakes such as Hileman and others (1973), Hill and others (1975a), and Friedman and others (1976)...
Analyses of natural gases from Gulf of Mexico Outer Continental Shelf
Dudley D. Rice, Charles N. Threlkeld
1978, Open-File Report 78-428
This report contains analyses and related source data for natural gas samples from 32 fields in the Gulf of Mexico OCS (Outer Continental Shelf).The interpretation of this data, along with analyses from other fields in Texas, is still in progress....
Stamukhi shoals of the Arctic - some observations from the Beaufort Sea
Erk Reimnitz, Douglas K. Maurer
1978, Open-File Report 78-666
A number of linear shoals, representing pronounced topographic anomalies on the surface of the Arctic shelf, have been studied in the Prudhoe Bay area. These shoals have been referred to in several previous studies. Based on seismic reflection records, Reimnitz et al., (1972a), stated that the shoals are constructional features...
The Bangui magnetic anomaly, Central African Empire: Final trip report
Robert D. Regan
1978, Open-File Report 78-1006
For the past 5 years the U. S. Geological Survey (USGS) and the National Aeronautics and Space Administration (NASA) have been involved in a joint project concerning the analysis of satellite magnetometer data for geological studies. The principal objectives of this project have been the detection, identification, and interpretation of...
Use and interpretation of strong-motion records from highway bridges
J.D. Raggett, Christopher Rojahn
1978, Open-File Report 78-707
This report describes how strong-motion records obtained from the earthquake-induced motions of highway bridges may be analyzed for use in the evaluation of bridge designs and bridge design procedures.This report is divided into five principal sections. The first section describes strong-motion instrumentation and strong-motion records. In the second section, a...
Chemical, physical, biochemical, and bacteriological characteristics at selected stream sites in Puerto Rico, 1976-77
Ferdinand Quinones-Marquez, Pedro Vasquez, Rafael Pena Cortes
1978, Open-File Report 78-445
In 1969, the Caribbean District of the U.S. Geological Survey, in cooperation with the Commonwealth of Puerto Rico, initiated the operation of a network to monitor some parameters indicative of water-quality changes at selected stream sites. The initial network consisted of 18 stations, which were expanded to 20 in 1971,...
Lunar landscape morphometry
Richard J. Pike
1978, Open-File Report 78-812
This report outlines some general methods for analyzing the geometry of planetary topography and illustrates them with results obtained for the Moon. Its contents apply to selection of landing sites for spacecraft, planning traverses for vehicles, and to other aspects of planetary exploration that involve numerical expression of topographic form...
ADEPT: a program to estimate depth to magnetic basement from sampled magnetic profiles
Jeffrey D. Phillips
1978, Open-File Report 79-367
A fortran program computes depth to magnetic basement from the spatially varying autocorrelation function of a sampled magnetic profile. The depth calculation assumes a particular form for the autocorrelation function, and this assumption is tested against the measured autocorrelation function in order to reject invalid depth estimates....
Principal facts for a gravity survey of the Gerlach Extension Known Geothermal Resource Area, Pershing County, Nevada
Donald L. Peterson, Harold E. Kaufmann
1978, Open-File Report 78-107-B
During July 1977, fifty-one gravity stations were obtained in the Gerlach Extension Known Geothermal Resource Area and vicinity, northwestern Nevada. Elevations for twenty-seven stations were estimated from lake bed topographic contours. Horizontal positions for these stations were determined from topographic maps and vehicle odometer....
Directory of local assistance centers of the National Water Data Exchange (NAWDEX)
Melvin D. Edwards
1978, Open-File Report 78-162
The National Water Data Exchange (NAWDEX), managed by the U.S. Geological Survey, has established a network of Local Assistance Centers throughout the United States and Puerto Rico to assist users of water data in identifying and locating the data they need. This up-dated Directory provides the information needed to contact...
