Plant microfossils from the Lakota Formation
Robert H. Tschudy, Sharon D. Van Loenen
1966, Open-File Report 66-134
As a part of continuing studies to provide palynological data from critical sequences for comparative biostratigraphic studies, the microfossils found in a sample of "Pine Needle" coal have been examined and photographed. The assemblage is presented on one plate....
Plant microfossils from the Fort Union Formation
Robert H. Tschudy, Sharon D. Van Loenen
1966, Open-File Report 66-133
As a part of continuing studies to provide palynological data from critical sequences for comparative biostratigraphic studies, the microfossils found in two Paleocene samples have been examined and photographed....
Methods for analysis of selected metals in water by atomic absorption
Marvin J. Fishman, Sanford C. Downs
1966, Water Supply Paper 1540-C
This manual describes atomic-absorption-spectroscopy methods for determining calcium, copper, lithium, magnesium, manganese, potassium, sodium, strontium and zinc in atmospheric precipitation, fresh waters, and brines. The procedures are intended to be used by water quality laboratories of the Water Resources Division of the U.S. Geological Survey. Detailed procedures, calculations, and methods...
Water in the Humboldt River Valley near Winnemucca, Nevada
Philip M. Cohen
1966, Water Supply Paper 1816
Most of the work of the interagency Humboldt River Research Project in the Winnemucca reach of the Humboldt River valley has been completed. More than a dozen State and Federal agencies and several private organizations and individuals participated in the study. The major objective of the project, which began in...
Fresh-water discharge salinity relations in the tidal Delaware River
Walter B. Keighton
1966, Water Supply Paper 1586-G
Sustained flows of fresh water greater than 3,500, 4,400, and 5,300 cubic feet per second into the Delaware River estuary at Trenton, NJ assure low salinity at League Island, Eddystone, and Marcus Hook, respectively. When the discharge at Trenton is less than these critical values, salinity is very sensitive to...
Selected techniques in water resources investigations, 1965
1966, Water Supply Paper 1822
Increasing world activity in water-resources development has created an interest in techniques for conducting investigations in the field. In the United States, the Geological Survey has the responsibility for extensive and intensive hydrologic studies, and the Survey places considerable emphasis on discovering better ways to carry out its responsibility. For...
Utilization of ground water in the Santa Maria Valley area, California
G.A. Miller, R. E. Evenson
1966, Water Supply Paper 1819-A
Overdraft in the Santa Maria Valley ground-water basin since about 1946 has resulted in a significant decline in water levels throughout the basin as ground water has been removed from storage. In 1959 approximately 2,200,000 acre-feet of ground water was in storage above sea level in the ground-water reservoir. Estimates...
Summary of hydrologic conditions of the Louisville area, Kentucky
Edwin Allen Bell
1966, Water Supply Paper 1819-C
Water problems and their solutions have been associated with the growth and development of the Louisville area for more than a century. Many hydrologic data that aided water users in the past can be applied to present water problems and will be helpful for solving many similar problems in the...
