Map showing the depth to the base of the deepest ice-bearing permafrost as determined from well logs, North Slope, Alaska
T. S. Collett, K. J. Bird, K.A. Kvenvolden, L. B. Magoon
1989, Oil and Gas Investigation Map 222
Because gas hydrates from within a limited temperature range, subsurface equilibrium temperature data are necessary to calculate the depth and thickness of the gas-hydrate stability field.  Acquiring these data is difficult because drilling activity often disrupts equilibrium temperatures in the subsurface, and a well mush lie undisturbed until thermal equilibrium...
Water resources data, Washington, water year 1988
M.B. Miles, W.D. Wiggins, G.P. Ruppert, R.L. Blazs, L.L. Reed, L.E. Hubbard
1989, Water Data Report WA-88-1
Water-resources data for the 1988 water year for Washington consist of records of stage, discharge, and water quality of streams; stage, contents, and water quality of lakes and reservoirs; and water levels of wells. This report contains discharge records for 202 gaging stations; stage only records for 6 gaging stations;...
Map showing earthquake epicenters (1964-81) in Yellowstone National Park and vicinity, Wyoming, Idaho, and Montana
A.D. Pitt
1989, Miscellaneous Field Studies Map 2022
The earthquake activity in the Yellowstone region is part of a belt of seismicity extending from southern Utah to northwestern Montana. The 1959 magnitude 7.3 Hebgen Lake earthquake is the largest historical event along this trend. Yellowstone National Park is also the focus of extensive Quaternary volcanic activity that relates...
Hydraulic characteristics of the New River in the New River Gorge National River, West Virginia
J.B. Wiley, David H. Appel
1989, Open-File Report 89-243
Traveltime, dispersion, water-surface and streambed profiles, and cross-section data were collected for use in application of flow and solute-transport models to the New River in the New River Gorge National River, West Virginia. Dye clouds subjected to increasing and decreasing flow rates (unsteady flow) showed that increasing flows shorten the...
Sedimentation survey of Lago Dos Bocas, Puerto Rico, June 1985
Ferdinand Quinones, Frank Melendez, Carlos Bonnet
1989, Open-File Report 86-241
A survey of the sedimentation of Dos Bocas reservoir, in central Puerto Rico, was conducted during July 1985. The survey showed that the capacity of the reservoir has declined from 30,420 acre-ft in 1942 to about 19,620 acre-ft. Sediment is accumulating in the reservoir at an average rate of about...
XAP, a program for deconvolution and analysis of complex X-ray spectra
James E. Quick, Abdul Malik Haleby
1989, Open-File Report 89-338
The X-ray analysis program (XAP) is a spectral-deconvolution program written in BASIC and specifically designed to analyze complex spectra produced by energy-dispersive X-ray analytical systems (EDS). XAP compensates for spectrometer drift, utilizes digital filtering to remove background from spectra, and solves for element abundances by least-squares, multiple-regression analysis. Rather than...
Analytical solutions for one-, two-, and three-dimensional solute transport in ground-water systems with uniform flow
Eliezer J. Wexler
1989, Open-File Report 89-56
Analytical solutions to the advective-dispersive solute-transport equation are useful in predicting the fate of solutes in ground water. Analytical solutions compiled from available literature or derived by the author are presented in this report for a variety of boundary condition types and solute-source configurations in one-, two-, and three-dimensional systems...
