1982, Open-File Report 82-353
Specific conductance and dissolved chloride reconnasissance sampling was conducted in six oil-producing areas of Mississippi during periods of low streamflow in 1980 and 1981. Water samples were collected at 224 ground-water and 190 suface-water sites. Samples from 55 surface-water and 17 ground-water sites contained dissolved chloride concentrations in excess of...

Prediction of earthquake response spectra
W. B. Joyner, David M. Boore
1982, Open-File Report 82-977
We have developed empirical equations for predicting earthquake response spectra in terms of magnitude, distance, and site conditions, using a two-stage regression method similar to the one we used previously for peak horizontal acceleration and velocity. We analyzed horizontal pseudo-velocity response at 5 percent damping for 64 records of 12...
Estimation of response-spectral values as functions of magnitude, distance, and site conditions
W. B. Joyner, David M. Boore
1982, Open-File Report 82-881
We have developed empirical predictive equations for the horizontal pseudo-velocity response at 5-percent damping for 12 different periods from 0.1 to 4.0 s. Using a multiple linear-regression method similar to the one we used previously for peak horizontal acceleration and velocity, we analyzed response spectra period by period for 64...
Thermodynamic properties of selected uranium compounds and aqueous species at 298.15 K and 1 bar and at higher temperatures; preliminary models for the origin of coffinite deposits
B. S. Hemingway
1982, Open-File Report 82-619
Thermodynamic values for 110 uranium-bearing phases and 28 aqueous uranium solution species (298.15 K and l bar) are tabulated based upon evaluated experimental data (largely from calorimetric experiments) and estimated values. Molar volume data are given for most of the solid phases. Thermodynamic values for 16 uranium-bearing phases are presented...
Production and decomposition of forest litter fall on the Apalachicola River flood plain, Florida
John F. Elder, Duncan J. Cairns
1982, Open-File Report 82-252
Measurements of litter fall (leaves and other particulate organic material) and leaf decomposition were made on the bottom-land hardwood swamp of the Apalachicola River flood plain in 1979-80. Litter fall was collected monthly from nets located in 16 study plots. The plots represented five forest types in the swamp and...

Annual snowmelt and rainfall peak-flow data on selected foothills region streams, South Platte River, Arkansas River, and Colorado River basins, Colorado
J. G. Elliott, R.D. Jarrett, J.L. Ebling
1982, Open-File Report 82-426
Peak flows in the foothills region of Colorado are attributable to two meteorological sources--snowmelt and rainfall. As part of a study of the hydrology of foothills streams in Colorado, charts from streamflow gages on unregulated streams were examined to determined the source of peak-flow events. Snowmelt-runoff peaks were distinguished from...
Origin of intraformational folds in the Jurassic Todilto Limestone, Ambrosia Lake uranium mining district, McKinley and Valencia counties, New Mexico
M. W. Green
1982, Open-File Report 82-69
The Todilto Limestone of Middle Jurassic age in the Ambrosia Lake uranium mining district of McKinley and Valencia Counties, New Mexico, is the host formation for numerous small- to medium-sized uranium deposits in joints, shear zones, and fractures within small- to large-scale intraformational folds. The folds probably were formed as...

1982, Open-File Report 82-130
One Landsat image in south-central Tunisia was analyzed to demonstrate the application of remote-sensing technology to regional development. A preliminary analysis included I) major landscape features; 2) gypsum-encrusted soils; and 3) phosphate-bearing beds exposed in the Gafsa mining district. The products specifically used for this report include: 1) A false-color...
Small-stream flood investigations in Minnesota, October 1958 to September 1980
