1964, Crustal Studies Technical Letter 23
The U.S. Geological Survey complete d a seismic-refraction survey in the vicinity of the Tonto Forest Seismological Observatory (T.F.S.O.) in April and May 1964. More than 1200 km of reversed profiles were surveyed to determine the crustal structure and crustal and upper mantle velocities in this area. The purpose of...
Crustal structure between Lake Mead, Nevada, and Mono Lake, California
Lane R. Johnson
1964, Crustal Studies Technical Letter 22
Interpretation of a reversed seismic-refraction profile between Lake Mead, Nevada, and Mono Lake, California, indicates velocities of 6.15 km/sec for the upper layer of the crust, 7.10 km/sec for an intermediate layer, and 7.80 km/sec for the uppermost mantle. Phases interpreted to be reflections from the top of the intermediate...
Seismic-refraction measurements of crustal structure between American Falls Reservoir, Idaho, and Flaming Gorge Reservoir, Utah
Ronald Willden
1964, Crustal Studies Technical Letter 21
Interpretation of a reversed seismic-refraction profile recorded between American Falls reservoir and Flaming Gorge reservoir in May 1963 indicates that the depth to the Mohorovicic discontinuity is about 31 km at American Falls and 37 km at Flaming Gorge. The existence of an intermediate crustal layer at a depth of...

1964, Water Investigation 3
The water resources of Van Buren County include productive ground-water reservoirs, a network of perennial streams, about 60 major inland lakes, and Lake Michigan. Most water users obtain their supplies from wells. The ground-water reservoirs in the glacial drift can provide several times the amount of water now used, but...
Hydrologic conditions: Dade County, Florida

1964, Florida Geological Survey Report of Investigations 24
Thin layers of dense limestone of low permeability that occur near the top of the Biscayne aquifer in the vicinity of the north end of Levee 30 in Dade County, Florida are of hydrologic importance because they retard the downward infiltration of ponded water in Conservation Area No. 3. This...
Water-resources data for Alachua, Bradford, Clay, and Union Counties, Florida

1964, Florida Geological Survey Information Circular 43
A study of the water resources of Alachua, Bradford, Clay, and Union counties, Florida (fig. 1), was made by the Water Resources Division of the U. S. Geological Survey in cooperation with the Florida Geological Survey during the period 1957-61. The results of this study will be published by the...

Water Quality Records in California
1964, Water Data Report CA-64
The quality-of-water investigations of the U.S. Geological Survey are concerned with the chemical and physical characteristics of surface and ground water supplies of the Nation in conjunction with water usage and its availability. The basic records for the 1964 water year for quality of surface waters within the State of...

Variations in regional traveltimes
J. H. Healy
1964, Crustal Studies Technical Letter 16
Precise epicentral location of a seismic event is made difficult by variations in regional traveltimes. A discussion is presented on delays to be expected in the various segments of a generalized travel path of seismic waves. Traveltime variations caused by changes in crustal structure and velocity introduce a major part...
Crustal structure in the eastern Colorado Plateaus Provence from seismic-refraction measurements
John C. Roller
1964, Crustal Studies Technical Letter 19
A reversed seismic-refraction profile was recorded in the Colorado Plateaus Province from Hanksville, Utah, to Chinle, Arizona, The velocity of Pg is 6.2 km/sec, and the true velocity of Pn is 7.8 km/sec, Waves identified as reflections indicate that an intermediate layer in the crust has a velocity of approximately...
Preliminary report on some factors affecting shotpoint efficiency
W. H. Jackson, J. H. Healy
1964, Crustal Studies Technical Letter 17
A study of first-arrival amplitudes from 6 water shotpoints and 7 drill-hole shotpoints in parts of central and western United States indicate a variation of over 100 to 1 between the best and poorest shotpoints. Water shotpoints are, in general, superior to drill-hole shotpoints; however, one drill-hole shotpoint produced higher...
Compilation of seismic-refraction crustal data in the Soviet Union

1964, Crustal Studies Technical Letter 18
The U.S. Geological Survey is preparing a series of terrain atlases of the Sino-Soviet bloc of nations for use in a possible nuclear-test detection program. Part of this project is concerned with the compilation and evaluation of crustal-structure data. To date, a compilation has been made of data from Russian...
Continental crust
L. C. Pakiser
1964, Crustal Studies Technical Letter 20
The structure of the Earth’s crust (the outer shell of the earth above the M-discontinuity) has been intensively studied in many places by use of geophysical methods. The velocity of seismic compressional waves in the crust and in the upper mantle varies from place to place in the conterminous United...
A merganser die-off associated with larval eustrongylides

1964, Avian Diseases (8) 420-427
A die-off of red-breasted mergansers on Lake Holly, Virginia Beach, Virginia, was found to be due to a larval Eustrongylides. Massive tissue destruction and hemorrhage was produced by the migration of the larval Eustrongylides. Earlier stages of the same Eustrongylides were found in eastern mosquitofish and silversides upon which the...

1964, Audubon Field Notes (18) 151-152
Nocturnal habitats used by American woodcock (Scolopux minor) were studied using radio telemetry at two coastal wintering sites in Georgia (1982-84) and Virginia (1991-92). In Georgia, use of forested habitats at night was extensive while use of fields at night varied between years but generally was low. We found no...
