Sonoran Pronghorn Literature: An Annotated Bibliography
Paul R. Krausman, John R. Morgart, Lisa K. Harris, Chantal S. O’Brien, James W. Cain III, Steve S. Rosenstock
2005, Open-File Report 2005-1265
EXECUTIVE SUMMARY The Sonoran pronghorn (Antilocapra americana sonoriensis) is 1 of 5 subspecies of pronghorn in North America. Sonoran pronghorn historically ranged from eastern California into southeastern Arizona and south to Sonora, Mexico. Sonoran pronghorn currently inhabit the Sonoran Desert in Southwestern Arizona and northern Sonora, Mexico. Unfortunately, their future in...
Catalog of earthquake hypocenters at Alaskan volcanoes: January 1 through December 31, 2004
James P. Dixon, Scott D. Stihler, John A. Power, Guy Tytgat, Steve Estes, Stephanie Prejean, John J. Sanchez, Rebecca Sanches, Stephen R. McNutt, John Paskievitch

The Alaska Volcano Observatory (AVO), a cooperative program of the U.S. Geological Survey, the Geophysical Institute of the University of Alaska Fairbanks, and the Alaska Division of Geological and Geophysical Surveys, has maintained seismic monitoring networks at historically active volcanoes in Alaska since 1988. The primary objectives of the seismic...
Developing ecological criteria for prescribed fire in South Florida pine rockland ecosystems
James R. Snyder, Michael S. Ross, Suzanne Koptur, Jay P. Sah
2005, Open-File Report 2006-1062
The pine rocklands of South Florida, characterized by a rich herbaceous flora with many narrowly endemic taxa beneath an overstory of south Florida slash pine (Pinus elliottii var. densa), are found in three areas: the Miami Rock Ridge of southeastern peninsular Florida, the Lower Florida Keys, and slightly elevated portions...
Questa baseline and pre-mining ground-water quality invistigation. 13. Mineral microscopy and chemistry of mined and unmined porphyry molybdenum mineralization along the Red River, New Mexico: Implications for ground- and surface-water quality
Geoff Plumlee, Heather Lowers, Steve Ludington, Alan Koenig, Paul Briggs
2005, Open-File Report 2005-1442
This report is one in a series presenting results of an interdisciplinary U.S. Geological Survey (USGS) study of ground-water quality in the lower Red River watershed prior to open-pit and underground molybdenite mining at Molycorp's Questa mine. The stretch of the Red River watershed that extends from just upstream of...
Locations and descriptions of gravity, box, and push cores collected in San Francisco Bay between January and February, 1990 and 1991
Roberto J. Anima, H. Edward Clifton, Carol Reiss, Florence L. Wong
2005, Open-File Report 2005-1453
A project to study San Francisco Bay sediments collected over 300 sediment gravity cores; six push cores, and three box cores in San Francisco Bay during the years 1990-91. The purpose of the sampling effort is to establish a database on the Holocene sediment history of the bay. The samples...
Global Positioning System measurements on the island of Hawai`i: 1997 through 2004
Asta Miklius, Peter Cervelli, Maurice Sako, Michael Lisowski, Susan Owen, Paul Segal, James Foster, Kevan Kamibayashi, Ben Brooks
2005, Open-File Report 2005-1425
This report summarizes GPS data and observations collected between 1997 and 2004 on the island of Hawai‘i with static surveying and continuously recording instruments. On Kīlauea, the long-term deformation field is dominated by steady southeastern velocities of more than 6 cm/year and uplift of about 2 cm/yr at stations on the...
libvaxdata: VAX data format conversion routines
Lawrence M. Baker
2005, Open-File Report 2005-1424
libvaxdata provides a collection of routines for converting numeric data-integer and floating-point-to and from the formats used on a Digital Equipment Corporation1 (DEC) VAX 32-bit minicomputer (Brunner, 1991). Since the VAX numeric data formats are inherited from those used on a DEC PDP-11 16-bit minicomputer, these routines can be used...
Geochemical Analyses of Geologic Materials from Areas of Critical Environmental Concern, Clark and Nye Counties, Nevada
Steve Ludington, Stephen B. Castor, James R. Budahn, Kathryn S. Flynn
2005, Open-File Report 2005-1450
INTRODUCTION An assessment of known and undiscovered mineral resources of selected areas administered by the Bureau of Land Management (BLM) in Clark and Nye Counties, Nevada was conducted by the U.S. Geological Survey (USGS), Nevada Bureau of Mines and Geology (NBMG), and University of Nevada, Las Vegas (UNLV). The purpose of...
Digital method for regional mapping of surficial basin deposits in arid regions, example from central Death Valley, Inyo County, California
A. S. Jayko, C.M. Menges, R. A. Thompson
2005, Open-File Report 2005-1445
Derivative maps generated from DEM's and panchromatic remote sensing data (TM Landsat 7 or SPOT) can be used to characterize surficial basin deposits in arid regions dominated by basin and range topography. Results indicate the technique is useful for rapid digital mapping of surficial deposits where a first order, systematic...
