Principal facts for gravity stations in Dixie; Fairview, and Stingaree valleys, Churchill and Pershing counties, Nevada
D. H. Schaefer, J. M. Thomas, B.G. Duffrin
1984, Open-File Report 84-586
During March through July 1979, gravity measurements were made at 300 stations in Dixie Valley, Nevada. In December 1981, 45 additional stations were added--7 in Dixie Valley, 23 in Fairview Valley, and 15 in Stingaree Valley. Most altitudes were determined by using altimeters or topographic maps. The gravity observations were...

J. C. Petersen, E. E. Morris
1984, Open-File Report 84-727
This report represents water-quality, sediment oxygen demand, phytoplankton, periphyton, bacteria, instantaneous and mean-daily discharge, stream geometry, time of travel, reaeration data and other water quality collected on the lower Ouachita River (from just upstream of Little Missouri River to Lock and Dam 6), West Two Bayou, Smackover Creek, Haynes Creek...
Spectral analysis of aeromagnetic profiles for depth estimation principles, software, and practical application
H.S. Sadek, S.M. Rashad, H. R. Blank
1984, Open-File Report 84-849
Fourier spectral analysis in recent years has become a widely utilized tool for the processing and interpretation of potential field data. It is particularly well suited to analysis of aeromagnetic maps and profiles, where coverage commonly is of broad scope and statistical treatment is appropriate. The techniques developed by earlier workers...
