Phytoplankton Abundance and Generic Composition Data for the Potomac River and Estuary, Maryland
R.R.H. Cohen, S.O. Pollock, V.E. Stoelzel, K.E. Boulukos
1985, Open-File Report 84-859
Phytoplankton of the Potomac River and Estuary were counted and identified to the generic level. Double-blind precision tests for an individual counter yielded a standard deviation that was * 10 percent of the mean. Differences between three counters exceeded * 10 percent, and a curve could be fit to calibration...
Aeromagnetic maps of the Latir Peak and Wheeler Peak Wildernesses and the Columbine-Hondo Wilderness Study Area, Taos County, New Mexico
C. K. Moss, G. A. Abrams
1985, Miscellaneous Field Studies Map 1570-C
This report interprets data from a helicopter-borne magnetic survey to help delineate subsurface geology. Such data, acquired near the ground, reflect greater magnetic detail than do data acquired at higher altitude. Data from a high-altitude reconnaissance aeromagnetic survey (U.S. Geological Survey, 1976) are used selectively to assist in the interpretation...
Maps showing distribution of barium in heavy-mineral concentrates, Richfield 1 degree by 2 degrees Quadrangle, Utah
William R. Miller, Jerry M. Motooka, John B. McHugh
1985, Miscellaneous Field Studies Map 1246-C
These maps are part of a folio of maps of the Richfield 1o x 2o quadrangle, Utach, prepared under the Conterminous United States Mineral Assessment Program. Other publications in this folio are listed in the selected references.  Located in west-central Utach, the Richfield quadrangle covers the eastern part of the Plioche-Marysvale ingeous...
Geochemical map of the Guadalupe Escarpment Wilderness Study Area, Eddy County, New Mexico
T.D. Light, J. A. Domenico, S. M. Smith
1985, Miscellaneous Field Studies Map 1560-B
During 1982, the U.S. Geological Survey and the U.S. Bureau of Mines conducted field investigations to evaluate the mineral resource potential of the Guadalupe Escarpment Wilderness Study Area. Field studies included geologic mapping, geochemical sampling, and a survey of known mines, prospects, and mineralized zones. This map presents the results...
Mineral resource potential maps of the Fiddler Butte Wilderness Study Area and the Fremont Gorge Study Area, Garfield and Wayne counties, Utah
M. J. Larson, R. F. Dubiel, Fred Peterson, W. R. Willson, J. P. Briggs
1985, Miscellaneous Field Studies Map 1755-A
Field and laboratory investigations of the Fiddler Butte WSA (Wilderness Study Area) in Garfield County, Utah, and of the Fremont Gorge study area in Wayne County, Utah, were made to determine the mineral resource potential of these lands. The investigations indicate that two areas in the northeastern and southwestern parts of the Fiddler...
Maps showing distribution of beryllium in heavy-mineral concentrates and stream sediments, Richfield 1 degree by 2 degrees Quadrangle, Utah
William R. Miller, Jerry M. Motooka, John B. McHugh
1985, Miscellaneous Field Studies Map 1246-D
These maps are part of a folio of maps of the Richfield 1o x 2o quadrangle, Utach, prepared under the Conterminous United States Mineral Assessment Program. Other publications in this folio are listed in the selected references.  Located in west-central Utach, the Richfield quadrangle covers the eastern part of the Plioche-Marysvale ingeous...
Preliminary study of the water-temperature regime of the North Santiam River downstream from Detroit and Big Cliff dams, Oregon
Antonius Laenen
1985, Water-Resources Investigations Report 84-4105
A riverine-temperature model and associated data-collection system were developed to help the Corps of engineers determine cost benefits of selective-withdrawal structures for future use with dams on the Willamette River System. A U.S. Geological Survey Lagrangian reference frame, digital computer model was used to simulate stream temperatures on the North...
