Managers' summary - Ecological studies of the Pryor Mountain Wild Horse Range, 1992-1997
F. J. Singer, K.A. Schoenecker
2000, Book
Ecological Studies of the Pryor Mountain Wild Horse Range, 1992-1997 provides a synthesis of key findings of landscape-scale, interdisciplinary studies of the effects of wild horses and native ungulates on a rugged, mountain ecosystem. This is perhaps the most comprehensive study of a wild horse herd conducted. This...
Effects of introduced crayfish on selected native fishes of Arizona
J. Carpenter
2000, Thesis
The virile crayfish (Orconectes virilis), an aggressive polytrophic species, has been introduced into many Arizona streams. I investigated competition and predation between this crayfish and several native Arizona fishes. I conducted field experiments to assess competition for food between crayfish and fish, and laboratory experiments to examine competition for shelter...

SNTEMP (In)frequently asked questions
J.M. Bartholow
2000, Report
Here, you will find a series of questions and answers resulting from many years of technical assistance with SNTEMP and SSTEMP. These (in)frequently asked questions are presented here so that you may get a feel for the range of questions posed, learn from the questions and their 'answers,' and share...

Publications of the U.S. Geological Survey, 1999
Water Resources Division, U.S. Geological Survey
2000, Report
This catalog is a list of (1) books and maps that were published during 1998 and (2) articles by U.S. Geological Survey personnel in non-U.S. Geological Survey journals and books that came to our attention in 1998; it supplements the permanent catalogs "Publications of the Geological Survey, 1879-1961," "Publications of...
Non-destructive measurement of soil liquefaction density change by crosshole radar tomography, Treasure Island, California
Robert E. Kayen, Walter A. Barnhardt, Scott Ashford, Kyle Rollins
2000, Book, Proceedings of Sessions of Geo-Denver 2000 - Computer Simulation of Earthquake Effects, GSP 110
A ground penetrating radar (GPR) experiment at the Treasure Island Test Site [TILT] was performed to non-destructively image the soil column for changes in density prior to, and following, a liquefaction event. The intervening liquefaction was achieved by controlled blasting. A geotechnical borehole radar technique was used to acquire high-resolution...
Relations of habitat-specific algal assemblages to land use and water chemistry in the Willamette Basin, Oregon
K.D. Carpenter, I.R. Waite
2000, Conference Paper, Environmental Monitoring and Assessment
Benthic algal assemblages, water chemistry, and habitat were characterized at 25 stream sites in the Willamette Basin, Oregon, during low flow in 1994. Seventy-three algal samples yielded 420 taxa - Mostly diatoms, blue-green algae, and green algae. Algal assemblages from depositional samples were strongly dominated by diatoms (76% mean relative...
Authigenic molybdenum formation in marine sediments: A link to pore water sulfide in the Santa Barbara Basin
Yen Zheng, Robert F. Anderson, A. VanGeen, J. Kuwabara
2000, Geochimica et Cosmochimica Acta (64) 4165-4178
Pore water and sediment Mo concentrations were measured in a suite of multicores collected at four sites along the northeastern flank of the Santa Barbara Basin to examine the connection between authigenic Mo formation and pore water sulfide concentration. Only at the deepest site (580 m), where pore water sulfide...
Pollen-based biomes for Beringia 18,000, 6000 and 0 14C yr BP
M. E. Edwards, P. M. Anderson, L.B. Brubaker, T. A. Ager, A.A. Andreev, N.H. Bigelow, L.C. Cwynar, Wendy R. Eisner, S. P. Harrison, F.-S. Hu, D. Jolly, A.V. Lozhkin, G. M. MacDonald, Cary J. Mock, J.C. Ritchie, A.V. Sher, R.W. Spear, J.W. Williams, G. Yu
2000, Journal of Biogeography (27) 521-554
The objective biomization method developed by Prentice et al. (1996) for Europe was extended using modern pollen samples from Beringia and then applied to fossil pollen data to reconstruct palaeovegetation patterns at 6000 and 18,000 14C yr BP. The predicted modern distribution of tundra, taiga and cool conifer forests in...
The art, history, and geoscience of Hindustan Whetstone gravestones in Indiana
E.P. Kvale, R.L. Powell, M.J. McNerney
2000, Journal of Geoscience Education (48) 333-336
Cemeteries can be intriguing places to people, in part because of a fascination with death but also because of the quiet solitude and artistic beauty found there. Many grave monuments are really works of art and can be appreciated on that basis alone. Cemeteries can also serve as teaching laboratories...
Measuring stream discharge by non-contact methods: A proof-of-concept experiment
J. E. Costa, K.R. Spicer, R. T. Cheng, F.P. Haeni, N.B. Melcher, E.M. Thurman, W.J. Plant, W.C. Keller
2000, Geophysical Research Letters (27) 553-556
This report describes an experiment to make a completely non-contact open-channel discharge measurement. A van-mounted, pulsed doppler (10GHz) radar collected surface-velocity data across the 183-m wide Skagit River, Washington at a USGS streamgaging station using Bragg scattering from short waves produced by turbulent boils on the surface of the river....
