Electronic thermal sensor and Landsat data collection platform technology
Duane M. Preble, Jules D. Friedman, David Frank
1977, Open-File Report 77-87
Five Data Collection Platforms (DCP) were integrated electronically with thermal 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 between...
Shelled benthic fauna of the eastern Chukchi Sea
Dennis M. Mann
1977, Open-File Report 77-672
The purposes of this study were to identify the benthic shelled infauna and epifauna of the eastern Chukchi Sea, compile species lists and distribution maps, determine recurrent groups of species (communities), and examine the environmental parameters that may control the distribution of the faunal groups. The study was partly supported...
Summary appraisals of the Nation's ground-water resources; Souris-Red-Rainy region
Harold O. Reeder
1977, Open-File Report 77-565
A broad-perspective analysis of the ground-water resources and present and possible future water development and management in the Souris-Red-Rainy Region is presented. The region includes the basins of the Souris River within Montana and North Dakota; the Red River of the North in South Dakota, North Dakota, and Minnesota; and...
Preliminary study of sources and processes of enrichment of manganese in water from University of Rhode Island supply wells
William Dudley Silvey, Herbert E. Johnston
1977, Open-File Report 77-561
Concentrations of dissolved manganese have increased from 0.0 to as much as 3.3 mg/liter over a period of years in closely spaced University of Rhode Island supply wells. The wells tap stratified glacial deposits and derive part of their water from infiltration from a nearby river-pond system. The principal sources...
Limnological studies of the major streams in Chester County, Pennsylvania
Bruce W. Lium
1977, Open-File Report 77-462
The major streams in Chester County, Pennsylvania were studied to determine their environmental state, and to relate this condition to land- use patterns. A biological numerical rating system on a scale of 1 to 10 was developed to classify stream conditions. One indicates extremely toxic conditions and 10 balanced biological...
Chemical data and variation diagrams of igneous rocks from the Timber Mountain-Oasis Valley Caldera Complex, southern Nevada
W. D. Quinlivan, F. M. Byers
1977, Open-File Report 77-724
Silica variation diagrams presented here are based on 162 chemical analyses of tuffs, lavas, and intrusives, representative of volcanic centers of the Timber Mountain-Oasis Valley caldera complex and cogenetic rocks of the Silent Canyon ca1dera. Most of the volcanic units sampled are shown on the U.S. Geological Survey geologic map...
Reconnaissance geologic study of the Vazante zinc district, Minas Gerais, Brazil
Charles H. Thorman, Samir Nahass
1977, Open-File Report 77-630
The Vazante district, Minas Gerais, 130 km south of Paracatu, produces nearly all of Brazil's zinc metal. The district is situated on the western side of the Late Precambrian Bambul basin and along the eastern and leading edge of the north-trending Brazilian orogenic belt (ca. 600-500 m.y. old) that borders...
Preliminary geomagnetic data, College Observatory, Fairbanks, Alaska: February 1977
J.B. Townshend, J.E. Papp, M.J. Moorman, C.E. Deadmon, S.P. Tilton
1977, Open-File Report 77-300-B
The preliminary geomagnetic data included here is made available to scientific personnel and organizations, as part of a cooperative effort and on a data exchange basis because of the early need by some users. To avoid delay, all of the data is copied from original forms processed at the observatory;...
