Hydrogeologic unit map of the Piedmont and Blue Ridge provinces of North Carolina
Charles C. Daniel III, R.A. Payne
1990, Water-Resources Investigations Report 90-4035
The numerous geologic formations and rock types in the Piedmont and Blue Ridge provinces of North Carolina have been grouped into 21 hydrogeologic units on the basis of their water-bearing potential as determined from rock origin, composition, and texture. All major classes of rocks--metamorphic, igneous, and sedimentary--are present, although metamorphic...
Sand and gravel aquifers of Schuyler County, New York
Todd S. Miller
1990, Water-Resources Investigations Report 90-4073
Some sand and gravel aquifers in Schuyler County may be capable of supplying large quantities of drinking water. To obtain information needed for proper management and protection of the aquifers and to ensure an adequate water supply for the future, the U.S. Geological Survey, in coopations with the county, compiled...

1990, Water Resources Management (26) 1981-2014
Stable isotope data for dissolved carbonate, sulfate, and sulfide are combined with water composition data to construct geochemical reaction models along eight flow paths in the Madison aquifer in parts of Wyoming, Montana, and South Dakota. The sulfur isotope data are treated as an isotope dilution problem, whereas the carbon...
Effectiveness of the addition of alkaline materials at surface coal mines in preventing or abating acid mine drainage--Part 2. Mine site case studies
Keith Brady, Michael W. Smith, Richard L. Beam, Charles A. Cravotta III,
1990, Conference Paper, Proceedings of the 1990 Mining and Reclamation Conference and Exhibition
The effectiveness of preventing or ameliorating acid mine drainage (AMD) through the application of alkaline additives is evaluated for eight surface coal mines in Pennsylvania. Many of the mine sites had overburden characteristics that made prediction of post‐mining water quality uncertain. Alkaline materials were applied at rates ranging from 42...
Reference manual for generation and analysis of Habitat Time Series: version II
Robert T. Milhous, John M. Bartholow, Marlys A. Updike, Alan R. Moos
1990, Report, Instream Flow Information Paper 27
The selection of an instream flow requirement for water resource management often requires the review of how the physical habitat changes through time. This review is referred to as 'Time Series Analysis." The Tune Series Library (fSLIB) is a group of programs to enter, transform, analyze, and display time series data...
Chemical weathering in the Loch Vale Watershed, Rocky Mountain National Park, Colorado
M. Alisa Mast, James I. Drever, Jill Baron
1990, Water Resources Research (26) 2971-2978
Mineralogic, hydrologic, and geochemical data were used to determine the source of solutes to surface waters draining the Loch Vale Watershed (LVWS), an alpine-subalpine drainage located in the Front Range of Colorado. The flux of dissolved solids from LVWS is primarily controlled by interactions between snowmelt and materials derived from...
The chemistry of iron, aluminum, and dissolved organic material in three acidic, metal-enriched, mountain streams, as controlled by watershed and in-stream processes
Diane M. McKnight, Kenneth E. Bencala
1990, Water Resources Research (26) 3087-3100
Several studies were conducted in three acidic, metal-enriched, mountain streams, and the results are discussed together in this paper to provide a synthesis of watershed and in-stream processes controlling Fe, Al, and DOC (dissolved organic carbon) concentrations. One of the streams, the Snake River, is naturally acidic; the other two,...
Historical Landsat data comparisons: illustrations of land surface change
Matthew D. Cross
1990, Report
The U.S. Geological Survey's (USGS) EROS Data Center (EDC) has archived two decades of Landsat data, providing a rich collection of information about the dynamics of the Earth's land surface. Major changes to the surface features of the planet can be detected, measured, and studied using Landsat data. The effects...

1990, Waste Management and Research (9) 195-204
A field-scale soil liner was constructed to test whether compacted soil barriers in cover and liner systems could be built to meet the U.S. EPA saturated hydraulic conductivity requirement (⩽ 1 × 10−7 cm s−1). The 8 × 15 × 0.9 m liner was constructed in 15 cm compacted lifts using...
Tests of a habitat suitability model for black-capped chickadees
Richard L. Schroeder
1990, Report
The black-capped chickadee (Parus atricapillus) Habitat Suitability Index (HSI) model provides a quantitative rating of the capability of a habitat to support breeding, based on measures related to food and nest site availability. The model assumption that tree canopy volume can be predicted from measures of tree height and...
Coda duration magnitudes in central California: An empirical approach
Caryl A. Michaelson
1990, Bulletin of the Seismological Society of America (80) 1190-1204
A new empirical coda magnitude MD is presented for the central California seismic network (CALNET), in which station corrections are introduced to reduce the influence of hypocenter and station distributions. The new magnitude scale is obtained by relating the lapse-time τ^ to local magnitudes ML using data from 55 earthquakes with 1.1 ≦ ML ≤ 5.6...

Glenn D. DelGiudice, L. David Mech, Ulysses S. Seal
1990, Journal of Wildlife Management (54) 539-550
We examined the effects of undernutrition and recovery on body composition and blood and urinary profiles of 6 captive white-tailed deer (Odocoileus virginianus) between 18 December 1984 and 3 May 1985. Deer were weighed, and blood and urine were collected every 2 weeks from 10 January to 3 May. At...

Michael D. Samuel, Nondor T. Weiss, Donald H. Rusch, Scott R. Craven, Robert E. Trost, F. Dale Caswell
1990, Journal of Wildlife Management (54) 612-621
We used capture, harvest, and observation histories of Canada geese (Branta canadensis) banded in the Mississippi flyway, 1974-88, to examine the problem of neck-band retention. Methods for the analysis of survival data were used to estimate rates of neck-band retention and to evaluate factors associated with neck-band loss. Sex, age...

Arthur J. Horowitz, Frank A. Rinella, Paul J. Lamothe, Timothy L. Miller, Thomas K. Edwards, Richard L. Roche, David A. Rickert
1990, Environmental Science and Technology (24) 1313-1320
Detailed sampling and subsequent analyses of riverine suspended sediment obtained from six rivers in the United States indicate substantial differences in suspended sediment concentrations and possibly in some associated trace elements, depending on whether depth- and width-integrated, point, or pumping samples are used. In addition, the data from time-series, depth-integrated...
On the nature and rate of resurfacing of Venus
Raymond E. Arvidson, Robert E. Grimm, Roger J. Phillips, Gerald G. Schaber, Eugene Merle Shoemaker
1990, Geophysical Research Letters (17) 1385-1388
Crater production and obliteration are modeled for the plains of Venus, using: (1 ) the observed distribution of Venus-crossing asteroids and comets, (2) viscous relaxation of crater topography, and (3) erosion and burial by atmospheric, volcanic, and tectonic processes. Crater lifetimes are assumed to be proportional to...

K. Kelly Ellins, A. Roman-Mas, A. Lee
1990, Journal of Hydrology (115) 319-341
222Rn was used in the karst drainage basin of the Rio Grande de Manati in Puerto Rico to study groundwater/surface flow relationships. Locations of groundwater influx along two sections of the Rio Grande de Manati were identified. The 222Rn measurements were used together with stream discharge data in a mass balance...
Age estimates and uplift rates for late Pleistocene marine terraces: Southern Oregon portion of the Cascadia forearc
Daniel R. Muhs, Harvey M. Kelsey, Joseph F. Whelan, Galan W. McInelly
1990, Journal of Geophysical Research D: Atmospheres (95) 6685-6698
Interest in the Cascadia subduction zone has increased because recent investigations have suggested that slip along plates at certain types of convergent margins is characteristically accompanied by large earthquakes. In addition, other investigations have suggested that convergent margins can be broadly classified by the magnitude of their uplift rates. The...
Age determinations and growth rates of Pacific ferromanganese deposits using strontium isotopes
B.L. Ingram, J.R. Hein, G. L. Farmer
1990, Geochimica et Cosmochimica Acta (54) 1709-1721
87Sr86Sr ratios, trace element and REE compositions, and textural characteristics were determined for three hydrogenetic Fe-Mn crusts, one hydrothermal deposit, and two mixed hydrothermalhydrogenetic crusts from the Pacific. The Sr isotope data are compared to the Sr seawater curve for the Cenozoic to determine the ages and growth rates of...
