Ice gouge obliteration and sediment redistribution event: 1977-1978, Beaufort Sea, Alaska
Peter W. Barnes, Erk Reimnitz
1979, Open-File Report 79-848
In 1978 major changes in shelf morphology were observed during a routine re-survey of part of the inner shelf region of the central Beaufort Sea. Regional observations are coupled with a detailed diving and side-scan study of a single ice gouge of known age to develop a detailed description of...

Relation of sediment yield to climatic and physical characteristics in the Missouri River basin
P. R. Jordan
1979, Water-Resources Investigations Report 79-49
Data from 64 stream-sediment stations and reservoirs in the plains area and from 15 stream-sediment stations in the mountainous area were analyzed to determine the relation of sediment yield to basin characteristics. Data from each sediment station and reservoir represented at least 7 years of sediment discharge in the plains...

Quality of water in Bayou Casotte and Bayou Chico, Jackson County, Mississippi
Gene A. Bednar
1979, Open-File Report 79-1059
A short-term water-quality study on Bayou Casotte and Bayou Chico on the Mississippi Gulf Coast was conducted on July 25-27, 1978. The results of the study indicated that the chemical and physical properties and range of concentrations of several dissolved constituents in both estuaries varied during a tide cycle primarily...

Calc-alkaline plutonism along the Pacific rim of southern Alaska
Travis Hudson
1979, Open-File Report 79-953
Field, petrology, and age data on southern Alaska plutonic rocks now enable the delineation of eight calc-alkaline plutonic belts. These belts of plutons or batholithic complexes are curvilinear to linear and trend parallel or subparallel to the continental margin. The belts represent the principal loci of emplacement for plutons of...
Results of transient simulations of a digital model of the Arikaree Aquifer near Wheatland, southeastern Wyoming
Dwight T. Hoxie
1979, Open-File Report 79-1280
Revised ground-water pumpage data have been imposed on a ground-water flow model previously developed for the Arikaree aquifer in a 400 square-mile area in central Platte County, Wyo. Maximum permitted annual ground-water withdrawals of 750 acre-feet for industrial use were combined with three irrigation-pumping scenarios to predict the long-term effects...

Radiocarbon dates from the Hawaiian Islands: A compilation
M. Lea Kelley
1979, Open-File Report 79-1700
Radiocarbon dating has proved to be a useful tool for the correlation of events and their timing during the Quaternary. In the Hawaiian Islands, the application of this technique is providing a chronology of the geologic history that will serve as a framework for studies of volcanologic and related hazards,...

Ground-water data for Michigan, 1977
G.C. Huffman
1979, Open-File Report 79-332
The purpose of this report is to make available the 1977 records of water levels and related data for the principal aquifers of the State. These records and data provide a means for evaluating available ground-water supplies. Long- term records serve as a framework to which short-term records may be...
Programs EMCUPL and SCHCOPL: computation of electromagnetic coupling on a layered halfspace with complex conductivities
James P. Kauahikaua, Walter L. Anderson
1979, Open-File Report 79-1430
A number of efficient numerical computer algorithms are incorporated into a general program called EMCUPL, which calculates the electromagnetic (EM) coupling between two straight wires on the surface of a multilayered half space. Each layer has an isotropic conductivity which may be either real or complex. A second computer program,...
Projected effects of intermittent changes in withdrawal of water from the Arikaree Aquifer near Wheatland, southeastern Wyoming
Dwight T. Hoxie
1979, Open-File Report 80-15
Effects on streamflows and ground-water levels attributable to a proposed intermittent change in use and sites of withdrawal of 3 ,146 acre-feet of water from the Arikaree aquifer in central Platte County, WY, are assessed with a previously developed ground-water flow model. This water has been permitted for agricultural use...
