Basic data on urban storm-water quality, Portland, Oregon
Stuart W. McKenzie, Timothy L. Miller
1976, Open-File Report 76-594
To assess urban storm-water-quality characteristics in the metropolitan area of Portland, Oreg., seven drainage basins were selected with varying drainage areas, basin slopes, impervious areas, land uses, and active construction areas.  Automatic water-quality samplers, rain gages, and stream gages were installed in each basin.  From September 1, 1975, to may...
Geologic map of the Oxia Palus Quadrangle of Mars
D.E. Wilhelms
1976, IMAP 895
The Oxia Palus quadrangle contains three distinct geologic provinces: (1) an elevated cratered plateau that occupies three-fourths of the quadrangle and is similar to much of the southern hemisphere of Mars; (2) the low, relatively featureless Chryse Planitia in the northwest corner; and (3) a complex province of chaotic terrain...
Thermographic mosaic of Yellowstone National Park
Richard S. Williams Jr., Philip G. Hasell Jr., Albert N. Sellman, Harry W. Smedes
1976, Photogrammetric Engineering and Remote Sensing (42) 1315-1324
An uncontrolled thermographic mosaic, which covers most of the area of Yellowstone National Park, has been compiled. The recording of aerial thermographic data on videotape is established as one of the prerequisites for the preparation of more accurate mosaics. Post-mission processing of the videotape record can rectify the nadir line...
A qualitative evaluation of Landsat imagery of Australian rangelands
R.D. Graetz, David M. Carneggie, R. Hacker, C. Lendon, D.G. Wilcox
1976, The Australian Rangeland Journal (1) 53-59
The capability of multidate, multispectral ERTS-1 imagery of three different rangeland areas within Australia was evaluated for its usefulness in preparing inventories of rangeland types, assessing on a broad scale range condition within these rangeland types, and assessing the response of rangelands to rainfall events over large areas. For the...
Estudio general de la region del Lago Titicaca evaluando en forma preliminar un sistema de analisis interactivo de imagenes multiespectrales
C.E. Brockmann, William D. Carter
1976, Revista tecnica de Yacimientos Petroliferos fiscales Bolivianos (5) 5-31
ERTS-1 digital data in the form of computer compatible tapes provide the geoscientist with an unusual opportunity to test the maximum flexibility of the satellite system using interactive computers, such as the General Electric Image 100 System. Approximately 9 hours of computer and operator time were used to analyze...
The survival of coho salmon (Oncorhynchus kisutch) eggs in two Wisconsin tributaries of Lake Michigan
James E. Cloern
1976, American Midland Naturalist (96) 451-461
Natural reproduction of coho salmon (Oncorhynchus kisutch) in two Wisconsin tributaries of Lake Michigan (Little Scarboro Creek, Kewaunee Co., and Fischer Creek, Manitowoc Co.), is limited by an unusually high mortality of eggs and preemergent embryos. Of approximately 1800 coho salmon eggs planted in six study redds (spawning beds) within...
Limnological data for the major streams in Chester County, Pennsylvania
Bruce W. Lium
1976, Report
Limnological data on major streams in Chester County, Pennsylvania are tabulated to provide a base line as to the present stream conditions. As land-use patterns change and further urbanization takes place, it is anticipated that these data will serve as a basis for comparison of conditions in the future. The...

Ground-water resources of the White River Junction area, Vermont
Arthur L. Hodges Jr., David Butterfield
1976, Report
A study of the ground-water resources of the White River Junction area, Windsor County, Vermont, was begun in 1969 as part of a cooperative program between the Vermont Department of Water Resources and the U.S. Geological Survey. The purpose of the study was to provide technical appraisal of potential sources...
Ground-water resources of the Barre-Montpelier area, Vermont
Arthur L. Hodges Jr., David Butterfield
1976, Report
A study of the ground-water resources of the Barre - Montpelier area (fig. 1), Washington County, was begun in 1968 as part of a cooperative program between the Vermont Department of Water Resources and the U.S. Geological Survey. The purpose of the study is to provide technical appraisal of potential...
Hydrogeochemistry of Bermuda: A case history of ground-water diagenesis of biocalcarenites
L.N. Plummer, H. L. Vacher, F.T. MacKenzie, O.P. Bricker, L.S. Land
1976, Geological Society of America Bulletin (87) 1301-1316
Bermuda is composed of relatively young skeletal limestones currently undergoing diagenesis by the ground water passing through them. The saturated zone consists of separate fresh-water bodies laterally surrounded and underlain by extensive brackish aureoles, in which the meteoric water is mixed with sea water. The meteoric water enters the aquifer...
Trace-element variations at Summer Coon volcano, San Juan Mountains, Colorado, and the origin of continental-interior andesite
Robert A. Zielinski, Peter W. Lipman
1976, GSA Bulletin (87) 1477-1485
The Oligocene Summer Coon center, an eroded continental-interior volcano of the eastern San Juan Mountains, Colorado, was the source of magmas ranging in composition from basaltic andesite to rhyolite. Previous Pb and Sr isotope studies indicate derivation of the magmas from an isotopically homogeneous source. This study presents new data...
Heat-flow data and their relation to observed geothermal phenomena near Klamath Falls, Oregon
J.H. Sass, Edward A. Sammel
1976, Journal of Geophysical Research (81) 4863-4868
Two holes were drilled to depths of about 180 m in the Lower Klamath Lake basin south of Klamath Falls, Oregon, to obtain heat flow data and to provide estimates of the thermal conductivity of the valley fill. Twenty-nine thermal conductivity determinations on eight cores give a mean conductivity of...
