Audio-magnetotelluric methods in reconnaissance geothermal exploration
D.B. Hoover, C. L. Long
1976, Conference Paper, Proceedings: second United Nations Symposium on the development and use of geothermal resources, San Francisco, California, USA, 20-29 May 1975
An audio-magnetotelluric (AMT) system has been developed by the U.S. Geological Survey for low-cost reconnaissance exploration of geothermal regions. This is an electromagnetic sounding technique in which the scalar or Cagniard resistivity is computed at 12 frequencies logarithmically spaced from 7.5 to 18 600 Hz. Our system uses natural source...
Characteristics of aquifers in the northern Uinta Basin area, Utah and Colorado
J. W. Hood
1976, Technical Publication 53
This report presents a part of the results of an investigation of the hydrology of the northern Uinta Basin area by the U.S. Geological Survey in cooperation with the Division of Water Rights, Utah Department of Natural Resources. The purpose of the report is to summarize the hydraulic and geohydrologic...
Geology and geophysics of the southern Raft River Valley geothermal area, Idaho, USA
Paul L. Williams, Don R. Mabey, Adel A. R. Zohdy, Hans D. Ackermann, Donald B. Hoover, Kenneth L. Pierce, Steven S. Oriel
1976, Conference Paper, Proceedings: second United Nations Symposium on the development and use of geothermal resources, San Francisco, California, USA, 20-29 May 1975
The Raft River valley, near the boundary of the Snake River plain with the Basin and Range province, is a north-trending late Cenozoic downwarp bounded by faults on the west, south, and east. Pleistocene alluvium and Miocene-Pliocene tuffaceous sediments, conglomerate, and felsic volcanic rocks aggregate 2 km in thickness. Large...
A portable helium sniffer
Irving Friedman, E.H. Denton
1976, Journal of Research of the U.S. Geological Survey (4) 35-36
A portable helium sniffer has been developed for field use. The instrument is mounted in a four-wheel-drive pickup truck and can detect 50 parts per billion of helium in soil gas. The usefulness of helium sniffing in soil is being investigated as a prospecting tool in gas, oil, uranium, and...
Glaciomarine deposits of Miocene through Holocene age in the Yakataga Formation along the Gulf of Alaska margin, Alaska
George Plafker, W.O. Addicott
Thomas P. Miller, editor(s)
1976, Conference Paper, Recent and ancient sedimentary environments in Alaska: Proceedings of the Alaska Geological Society Symposium held April 2-4, 1975, at Anchorage, Alaska
Perhaps the world's longest and most complete onshore sedimentary record of late Cenozoic glaciation is preserved in the Gulf of Alaska Tertiary province that extends 800 km along the coast of southern Alaska. The Yakataga Formation, with an aggregate outcrop thickness of about 5,000 m, is characterized by variable amounts...
Beacon Hill end moraine, Boston: new explanation of an important urban feature
Clifford A. Kaye
Donald R. Coates, editor(s)
1976, Book chapter, Urban Gomorphology (Geological Society of America, Special Paper 174)
The usefulness of geology to engineers is in direct proportion to how well it helps us predict the subsurface; these predictions, in turn, depend on our knowledge of the geomorphic processes that molded the terrain. The uncertainties of interpretation are particularly great in glaciated terrain because our understanding of both...
Electronic thermal sensor and Data Collection Platform technology: Part 5 in Thermal surveillance of active volcanoes using the Landsat-1 Data Collection System
Duane M. Preble, Jules D. Friedman, David Frank
1976, Report, Thermal surveillance of active volcanoes using the Landsat-1 Data Collection System
Five Data Collection Platforms (DCP) were integrated electronically with thermall sensing systems, emplaced and operated in an analog mode at selected thermally significant volcanic and geothermal sites. The DCP's transmitted 3260 messages comprising 26,080 ambient, surface, and near-surface temperature records at an accuracy of ±1.15 °C for 1121 instrument days...
National Cartographic Information Center Newsletter No. 4
Water Resources Division, U.S. Geological Survey
1976, Newsletter 4
Last week, the editor of this publication was told to start signing the introduction. Something to do with credit given for work done. We look at it in the unfortunate light of accountability; our days under the bushel of anonymity are over. Speaking of accountability, it's about time we gave...
United States Geological Survey Annual Report, Fiscal Year 1975
Water Resources Division, U.S. Geological Survey
1976, Report
The Survey resumes the practice of annually summarizing the progress it has made in identifying the Nation's land, water, energy, and mineral resources, classifying federally owned mineral lands and waterpower sites, and in supervising the exploration and development of energy and mineral resources on Federal and Indian lands. The Annual...
Chart of conversion factors: From English to metric system and metric to English system
Water Resources Division, U.S. Geological Survey
1976, Report
The conversion factors in the following tables are for conversion of our customary (English) units of measurement to SI*units, and for convenience, reciprocals are shown for converting SI units back to the English system. The first table contains rule-of-thumb figures, useful for "getting the feel" of SI units or mental...
Man against volcano: The eruption on Heimaey, Vestmann Islands, Iceland
R.S. Williams Jr., J.G. Moore
1976, Report
The U.S. Geological Survey carries out scientific studies in the geological, hydrological, and cartographic sciences generally within the 50 states, but also in cooperation with scientific organizations in many foreign countries for the investigation of unusual earth science phenomena throughout the world. The following material discusses the impact of the...
Nature . . . an environmental yardstick
William T. Pecora
1976, Information and Technology Report 72-21
To one who has spent his professional career in geologic science, conservation always has had special meaning. In the measurements so necessary to his work the geologist develops an integrity in the use of numbers and in the qualifications attending the validity of numbers. Scientific analysis of geologic events and...
