Rapid heat-flowing surveying of geothermal areas, utilizing individual snowfalls as calorimeters
Donald E. White
1969, Journal of Geophysical Research (74) 5191-5201
Local differences in rate of heat transfer in vapor and by conduction through the ground in hot spring areas are difficult and time-consuming to measure quantitatively. Individual heavy snowfalls provide a rapid low-cost means of measuring total heat flow from such ground. After a favorable snowfall (heavy, brief duration, little...
Airborne fluorometer applicable to marine and estuarine studies
George E. Stoertz, William R. Hemphill, David A. Markle
1969, Marine Technology Society Journal (3) 11-26
An experimental Fraunhofer line discriminator detected solar-stimulated yellow fluorescence (5890 A) emitted by Rhodamine WT dye in aqueous solutions. Concentration of 1 part per billion was detected in tap water 1/2-meter deep. In extremely turbid San Francisco Bay, dye was monitored in concentrations of less than 5 parts per billion...
Some guidelines for remote sensing in hydrology
Charles J. Robinove, Daniel G. Anderson
1969, Journal of the American Water Resources Association (5) 10-19
Remote sensing in the field of hydrology is beginning to be applied to significant problems, such as thermal pollution, in many programs of the Federal and State Governments as well as in operation of many private organizations. The purpose of this paper is to guide the hydrologist to a better...
Structural geologic interpretations from radar imagery
Robert G. Reeves
1969, Geological Society of America Bulletin (80) 2159-2164
Certain structural geologic features may be more readily recognized on sidelooking airborne radar (SLAR) images than on conventional aerial photographs, other remote sensor imagery, or by ground observations. SLAR systems look obliquely to one or both sides and their images resemble aerial photographs taken at low sun angle with the...
Surveying the earth's resources from space
William T. Pecora
1969, TRW Space Log (9) 2-15
During the past 4 years, scientists of the Geological Survey, in cooperation with NASA, have been investigating the feasibility and practicality of using remote-sensor data collected during conventional aircraft flights. This work is aimed at developing techniques for gathering facts about the earth's natural resources from satellites carrying sophisticated remote-sensing...
Satellite imagery of the earth
P.M. Merifield, J. Cronin, L.L. Foshee, S.J. Gawarecki, J.T. Neal, R. E. Stevenson, R.O. Stone, R.S. Williams Jr.
1969, Photogrammetric Engineering (35) 654-668
Photography of the Earth from spacecraft has application to both atmospheric and Earth sciences. Gemini and Apollo photographs have furnished information on sea surface roughness, areas of potential upwelling and oceanic current systems. Regional geologic structures and geomorphologic features are also recorded in orbital photographs. Infrared satellite imagery provides meteorological...
The geographic applications program of the U. S. Geological Survey
Arch C. Gerlach
1969, Photogrammetric Engineering (35) 58-60
The fundamental objective of modern Geography is to improve man's level of living through a better understanding of man-environment inter actions. Related goals of the USGS program for applications of remote sensor data to Geographical research are: (1) the analysis and improvement of land use, with special emphasis on urban...
Finney County Basic Data
W.R. Meyer, E. D. Gutentag, D.H. Lobmeyer
1969, Report
This open-file report contains basic data on measurements and chemical analyses of ground water, logs of test holes, and summary information on selected logs for Finney County, Kans....
Ground-water data as of 1967, Central Coastal Subregion, California
J. S. Bader
1969, Report
Most usable ground water in the predominantly mountainous Central Coastal Subregion occurs in alluvium-filled valleys and coastal plains and in deeper aquifers of Quaternary and Tertiary age. The intervening mountainous areas are underlain by consolidated sedimentary, igneous, and metamorphic rocks, mainly of Mesozoic age. These older rocks contain only small...
A study of deep aquifers underlying coastal Orange County, California
Joe A. Moreland, John A. Singer
1969, Report
Deep untapped aquifers of late Pliocene age, which contain water having 1,000 to 2,000 milligrams per liter of dissolved solids, underlie most of the coastal part of Orange County. Inland from the Newport-Inglewood structural zone, the depth to the base of aquifers containing fresh water ranges from 1,000 to 2,500 feet...
