FD_BH: a program for simulating electromagnetic waves from a borehole antenna
Karl J. Ellefsen
2002, Open-File Report 2002-276
Program FD_BH is used to simulate the electromagnetic waves generated by an antenna in a borehole. The model representing the antenna may include metallic parts, a coaxial cable as a feed to the driving point, and resistive loading. The program is written in the C programming language, and the program...

Philip E. Wannamaker, William M. Doerner, John A. Stodt, Timothy L. Sodergen, Brian D. Rodriguez
2002, Open-File Report 2002-214
We have collected about 150 magnetotelluric (MT) soundings in northeastern Nevada in the region of the Ruby Mountains metamorphic core complex uplift and southern Carlin mineral trend, in an effort to illuminate controls on core complex evolution and deposition of world-class gold deposits. The region has experienced a broad range...
Merged digital aeromagnetic data for the middle Rio Grande and southern Espanola basins, New Mexico
Ronald E. Sweeney, V. J. S. Grauch, Jeffrey D. Phillips
2002, Open-File Report 2002-205
The U. S. Geological Survey (USGS) recently conducted a multi-disciplinary study of the Middle Rio Grande basin (Bartolino and Cole, 2002; Fig. 1). The main purpose of this study was to gain a better multi-dimensional understanding of the basin's hydrogeologic framework and use this new understanding to construct an improved...
Results of the U. S. Geological Survey's Analytical Evaluation Program for Standard Reference Samples Distributed in March 2002
M.T. Woodworth, B.F. Conner
2002, Open-File Report 2002-243
This report presents the results of the U.S. Geological Survey's analytical evaluation program for six standard reference samples -- T- 169 (trace constituents), M- 162 (major constituents), N-73 (nutrient constituents), N-74 (nutrient constituents), P-38 (low ionic-strength constituents), and Hg-34 (mercury) -- that were distributed in March 2002 to laboratories enrolled...

Water Resources Division, U.S. Geological Survey
2002, Open-File Report 2002-48
As part of the South Florida Water Management District's Ground Water-Surface Water Interactions Study, a project was undertaken to identify the ages and sources of water in the area of Pool C, Kissimmee River, Florida. Twenty-two water samples were collected along two transects: at a remnant river oxbows (Site D)...
