Relation of electrochemical potentials and iron content to ground-water flow patterns
William Back, Ivan Barnes
1965, Professional Paper 498-C
This study was undertaken to develop means of measuring oxidation potentials in aquifer systems and to use the measured values in interpreting the behavior of iron in ground water. Anne Arundel County, Md., was selected as the area of study because of the wide range of concentration of iron-nearly zero...
Variations in chemical character of water in the Englishtown Formation, New Jersey
Paul R. Seaber
1965, Professional Paper 498-B
This investigation describes the variations in the chemical character of the water in the Englishtown Formation of Late Cretaceous age in the Atlantic Coastal Plain of New Jersey, and demonstrates the application of the concept of hydrochemical mapping to the study and evaluation of water-bearing materials. The chemistry of ground water...
Resource understanding: a challenge to aerial methods
Stewart L. Udall
1965, Photogrammetric Engineering (31) 63-75
Aerial survey methods are speeding acquisition of survey data needed to provide and manage the nation's resources. These methods have been applied to topographic mapping for a number of years and the record clearly shows their advantages in terms of cost and speed in contrast to the ground methods that...
Photointerpretation of Alaskan post-earthquake photography
R.J. Hackman
1965, Photogrammetric Engineering (31) 604-610
Aerial photographs taken after the March 27, 1964, Good Friday, Alaskan earthquake were examined stereoscopically to determine effects of the earthquake in areas remote from the towns, highways, and the railroad. The two thousand black and white photographs used in this study were taking in April, after the earthquake,...
Geological exploration from orbital altitudes
Peter C. Badgley, William A. Fischer, Ronald J. P. Lyon
1965, Geotimes (10) 11-14
The National Aeronautics & Space Administration is planning geologic exploration from orbiting spacecraft. For that purpose it is evaluating new and refined exploration tools, often called remote sensors, including devices that are sensitive to force fields, such as gravity gradient systems, and devices that record the reflection or emission of...
Water resources data for Indiana, 1965
Water Resources Division, U.S. Geological Survey
1965, Water Data Report IN-65-1
The surface-water records for the 1965 water year for gaging stations, partial-record stations, and miscellaneous sites within the State of Indiana are given in this report. For convenience there are also included records for a few pertinent gaging stations in bordering States. The records were collected and computed by the...
Late quaternary geologic history of the lower Chippewa Valley, Wisconsin
George W. Andrews
1965, Bulletin of the Geological Society of America (76) 113-124
The lower Chippewa Valley in west-central Wisconsin extends 65 miles from the Cary terminal moraine in Chippewa County to the Mississippi River Valley. The Chippewa Valley and its tributaries were filled with a valley train of sand and gravel during the maximum stand of the Cary ice, and entrenchment of...
Ordovician, Silurian, and Devonian biostratigraphy of east-central Alaska
Michael Churkin Jr., Earl E. Brabb
1965, American Association of Petroleum Geologists Bulletin (49) 172-185
A predominantly shale and chert sequence has been mapped from the Canadian border at Latitude 65°00′ N. to the Nation River about 25 miles northwest. It has Ordovician and Silurian graptolites in the lower half, and Middle Devonian corals and Upper Devonian spores in the upper half.The lower half of...
Artifact from deposits of mid-Wisconsin age in Illinois
P.J. Munson, J.C. Frye
1965, Science (150) 1722-1723
Discovery of an artifact of human manufacture imbedded in Roxana loess, classed as Altonian substage of the Wisconsin stage of the Pleistocene, of an age of 35,000 to 40,000 years, contributes to the determination of the age of man in the New World....
