Aeromagnetic map of the Tanacross Quadrangle, Alaska
Andrew Griscom
1976, Miscellaneous Field Studies Map 767-A
The aeromagnetic map (sheet 1) of the Tanacross quadrangle was prepared in 1971 and subsequently released by the State of Alaska as an open-file map (Alaska Div. Geology and Geophysics, 1973). The data were collected along north-south traverses spaced at 1.6-km intervals and from an altitude of 300 m above...
Geologic map of the Hellas Quadrangle of Mars
D.B. Potter
1976, IMAP 941
The area of MC-28 is centered on the east edge of the Hellas Planitia (Hellas basin and surrounding plains) within densely cratered terrain that covers more than half the surface of Mars (Carr, 1973, fig....
Data for calibrating unsteady-flow sediment-transport models, East Fork River, Wyoming, 1975
Holly A. Mahoney, Edmund D. Andrews, William W. Emmett, Luna Bergere Leopold, Robert H. Meade, Robert M. Myrick, Carl F. Nordin
1976, Open-File Report 76-22
In 1975, data to calibrate a one-dimensional unsteady-flow and sediment-transport routing model were collected on a reach of the East Fork River of western Wyoming. The reach, 3.1 miles (5 kilometers) in length, wan immediately upstream from a previously established bedload sampling station. Nineteen channel cross sections were sounded at...
WATEQF; a FORTRAN IV version of WATEQ : a computer program for calculating chemical equilibrium of natural waters
Niel Plummer, Blair F. Jones, Alfred Hemingway Truesdell
1976, Water-Resources Investigations Report 76-13
WATEQF is a FORTRAN IV computer program that models the thermodynamic speciation of inorganic ions and complex species in solution for a given water analysis. The original version (WATEQ) was written in 1973 by A. H. Truesdell and B. F. Jones in Programming Language/one (PL/1.) With but a few exceptions,...
Potassium-argon ages of basement rocks from St. George Island, Alaska
Miles L. Silberman, David Moody Hopkins
1976, Open-File Report 76-733
St. George Island is one of the Pribilof Islands which lie between 56°35' and 57°11' N. lat. in the Bering Sea, 350 km north of the Aleutian chain. The islands are situated near the margin of the continental platform that underlies most of the northern half of the Bering Sea...
Summary of some current and possible future environmental problems related to geology and hydrology at Memphis, Tennessee
William Scott Parks, Richard W. Lounsbury
1976, Water-Resources Investigations Report 76-4
This report summarizes information concerning many aspects of the geology and hydrology at Memphis, Tenn. It also outlines some of the current problems related to the local geology and hydrology or ones that may arise as a result of urbanization and industrialization of the area. The city is in the...
Predicted effects of a proposed water-resources management plan in the lower San Luis Rey River Valley, California, using digital ground-water flow models
James A. Skrivan
1976, Open-File Report 76-754
A proposed plan for water-resource management in the lower San Luis Rey River valley, Calif. has been evaluated using digital models of ground-water flow. Two projections of water-level changes and salt balance in 1977 were made. The first projection used 1972 climatic and pumping conditions. The second projection used these...
