Food consumption and retention time in captive whooping cranes (Grus americana)
J.T. Nelson, G.F. Gee, R.D. Slack
1997, Zoo Biology (16) 519-531
Food consumption, digesta retention time, and food preference were measured for captive whooping cranes fed pelleted diets. The basal commercial diet was compared to four mixtures containing 70% basal and 30% of one of four important winter foods for the whooping crane: blue crab (Callinectes sapidus), wolfberry...
Tapir (Tapirus) enteroliths
M.R. Murphy, J.M. Masters, D.M. Moore, H.D. Glass, R.E. Hughes, S.D. Crissey
1997, Zoo Biology (16) 427-433
Enterolith fragments from two tapir species and horses were subjected to x-ray diffraction analysis. Tapir enteroliths were formed as layers of mineral deposited around a foreign nidus. The structure was similar to that of equine enteroliths except that tapir enteroliths lacked a central region of radially symmetrical coarse crystals. The...
Preliminary Volcano-Hazard Assessment for Redoubt Volcano, Alaska
Christopher F. Waythomas, Joseph M. Dorava, Thomas P. Miller, Christina A. Neal, Robert G. McGimsey
1997, Open-File Report 97-857
Redoubt Volcano is a stratovolcano located within a few hundred kilometers of more than half of the population of Alaska. This volcano has erupted explosively at least six times since historical observations began in 1778. The most recent eruption occurred in 1989-90 and similar eruptions can be expected in the...
Techniques for estimating peak flow on small streams in Minnesota
D. L. Lorenz, G.H. Carlson, C. A. Sanocki
1997, Water-Resources Investigations Report 97-4249
Two statistically-derived techniques, regional regression equation and region of influence regression, that estimate peak flow on small, ungaged streams in Minnesota were developed. Both techniques relate physical and climatic characteristics to peak flow for 2-, 5-, 10-, 25-, 50-, and 100-year recurrence intervals. Regional regression equations were developed for each recurrence...
National Geochemical Database: Reformatted data from the National Uranium Resource Evaluation (NURE) Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) program
Steven M. Smith
1997, Open-File Report 97-492
The National Uranium Resource Evaluation (NURE) Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) program produced a large amount of geochemical data. To fully understand how these data were generated, it is recommended that you read the History of NURE HSSR Program for a summary of the entire program. By the time the...
Progress report on sediment analyses at selected faunal monitoring sites in north-central and northeastern Florida Bay
T.M. Scott, G.H. Means, G. L. Brewster-Wingard
1997, Open-File Report 97-534
Florida Bay is a shallow, subtropical lagoon at the southern tip of the Florida peninsula. The 2200 square kilometer, triangular-shaped area is the site of modern carbonate sediment formation and deposition. The intricate ecosystem of the bay has undergone significant changes as the result of natural influences and human intervention....
Geologic map of the Dillon quadrangle, Summit and Grand Counties, Colorado
Karl S. Kellogg
1997, Open-File Report 97-738
New 1:24,000-scale geologic mapping along the Interstate-70 urban corridor in western Colorado, in support of the USGS Central Region State/USGS Cooperative Geologic Mapping Project, is contributing to a more complete understanding of the stratigraphy, structure, tectonic evolution, and hazard potential of this rapidly developing region. The 1:24,000-scale Dillon quadrangle...
Proceedings of a workshop on digital mapping techniques; methods for geologic map data capture, management, and publication - June 2 - 5, 1997, Lawrence, Kansas
David R. Soller
1997, Open-File Report 97-269
Introduction: From June 2-5, 1997, selected technical representatives of the USGS and State geological surveys participated in the 'AASG/USGS Digital Mapping Techniques' workshop in Lawrence, Kansas. The workshop was initiated by the AASG/USGS Data Capture Working Group, and was hosted by the Kansas Geological Survey (KGS). With a focus on...
Organochlorine compounds and trace elements in streambed sediment and fish tissue, South Platte River Basin; Colorado, Nebraska, and Wyoming
Janet S. Heiny
1997, Fact Sheet 040-97
Concentration data for organochlorine compounds and trace elements in streambed sediment and fish tissue collected throughout the South Platte River Basin as part of the U.S. Geological Survey's National WaterQuality Assessment (NAWQA) Program were evaluated to determine the following: (1) which organochlorine compounds and trace elements occurred most frequently, (2)...
Environmental setting and implications for water quality in the Western Lake Michigan Drainages
C.A. Peters, editor(s)
1997, Water-Resources Investigations Report 97-4196
In 1991, the U.S. Geological Survey began to implement its National Water-Quality Assessment (NAWQA) program. The Western Lake Michigan Drainages was one of 20 study units selected for investigation to begin in 1991. The study-unit investigation will include an assessment of surface- and ground-water quality. The quality of water in...
Results of quality-control sampling of water, bed sediment, and tissue in the Western Lake Michigan Drainages study unit of the National Water-Quality Assessment Program
S.A. Fitzgerald
1997, Water-Resources Investigations Report 97-4148
This report contains the quality control results of the Western Lake Michigan Drainages study unit of the National Water Quality Assessment Program. Quality control samples were collected in the same manner and contemporaneously with environmental samples during the first highintensity study phase in the unit (1992 through 1995) and amounted...
