Debris flow, debris avalanche, and flood hazards at and downstream from Mount Rainier, Washington
Kevin M. Scott, J.W. Vallance
1995, Hydrologic Atlas 729
Mount Rainier volcano has produced many large debris flows and debris avalanches during the last 10,000 years. These flows have periodically traveled more than 100 kilometers from the volcano to inundate parts of the now-populated Puget Sound Lowland. Meteorological floods also have caused damage, but future effects will be partly...

Postflood occurrence of selected agricultural chemicals and volatile organic compounds in near-surface unconsolidated aquifers in the upper Mississippi River basin, 1993
Dana W. Kolpin, E. Michael Thurman
1995, Circular 1120-G
The historic stream flooding and intense rainfall across the upper Mississippi River Basin during summer 1993 had an immediate effect on near-surface unconsolidated aquifers by raising the water levels closer to the land surface . The objective of this study was to determine if this flooding also had immediate effects...

Geologic and topographic maps of the Elysium Paleolake basin, Mars
D. H. Scott, M. G. Chapman
1995, IMAP 2397
These geologic and topographic maps show a basin in the Elysium region of Mars that is thought to have been the site of a large paleolake during the most recent period (Amazonian) in Mars’ history (Scott and Chapman, 1991b). The basin, referred to as the Elysium basin, extends for...
Transport of chromium and selenium in a pristine sand and gravel aquifer: Role of adsorption processes
D.B. Kent, J.A. Davis, L.C.D. Anderson, B.A. Rea
1995, Water Resources Research (31) 1041-1050
Field transport experiments were conducted in an oxic sand and gravel aquifer using Br (bromide ion), Cr (chromium, injected as Cr(VI)), Se (selenium, injected as Se(VI)), and other tracers. The aquifer has mildly acidic pH values and low concentrations of dissolved salts. Within analytical errors, all mobile Cr was present as...
Effect of increased water depth on growth of a common perennial freshwater-intermediate marsh species in Coastal Louisiana
Rebecca J. Howard, Irving A. Mendelssohn
1995, Wetlands (15) 82-91
The response of Sagittaria lancifolia to increased water depths of 7.5 and 15 cm was examined in this field study. Water-depth treatments were achieved by digging sods containing one or two individual plants or ramets of S. lancifolia from the marsh, removing sediment from the resulting hole, and replacing the...
Development of a DNA probe for the myxosporean parasite, Ceratomyxa shasta, using the polymerase chain reaction with arbitrary primers
Jerri L Bartholomew, Rusty J. Rodriguez, Cindy K. Arakawa
1995, Diseases of Aquatic Organisms (21) 215-220
The arbitrarily primed polymerase chain reaction (PCR) was used to generate a DNA marker specific for the myxosporean parasite Ceratomyxa shasta. The [32P]-labeled marker hybridized to purified C. shasta DNA and to parasite DNA combined with salmonid DNA in a dot blot assay, demonstrating its potential as a diagnostic tool. The amplified...
The M2 tide on the Amazon Shelf

1995, Journal of Geophysical Research C: Oceans (100) 2283-2319
As part of A Multidisciplinary Amazon Shelf Sediment Study (AMASSEDS), moored and shipboard current measurements made over the Amazon shelf during 1990–1991 have been analyzed to determine the dominant semidiurnal tidal constituent, the M2. These results have been combined with coastal sea level data from within the Amazon and Para...
Seismic refraction measurements within the Peninsular terrane, south central Alaska
Elizabeth L. Ambos, Walter D. Mooney, Gary S. Fuis
1995, Journal of Geophysical Research (100) 4079-4095
We present an interpretation of crustal seismic refraction data from the Peninsular terrane, one of the many exotic terranes that have been accreted to the continental margin of southern Alaska in the past 200 m.y. A seismic refraction line was collected along the Glenn Highway in the...
Mechanism of formation of humus coatings on mineral surfaces 1. Evidence for multidentate binding of organic acids from compost leachate on alumina
R.L. Wershaw, J.A. Leenheer, R.P. Sperline, Yuan Song, L.A. Noll, R.L. Melvin, G.P. Rigatti
1995, Colloids and Surfaces A: Physicochemical and Engineering Aspects (96) 93-104
Measurements of the infrared linear dichroism of carboxylate groups of organic acids from compost leachate adsorbed to an alumina surface and the enthalpy of adsorption of this reaction have been made. The linear dichroism measurements indicated that the carboxylate groups are not free to rotate. This limited rotation probably results...
Rapid deformation of the south flank of Kilauea volcano, Hawaii
S. Owen, P. Segall, Jeffrey T. Freymueller, Asta Mikijus, R. Denlinger, T. Arnadottir, M. Sako, R. Burgmann
1995, Science (267) 1328-1332
The south flank of Kilauea volcano has experienced two large [magnitude (M) 7.2 and M 6.1] earthquakes in the past two decades. Global Positioning System measurements conducted between 1990 and 1993 reveal seaward displacements of Kilauea's central south flank at rates of up to about 10 centimeters per year. In contrast, the...
Large-scale atmospheric forcing of recent trends toward early snowmelt runoff in California
Michael D. Dettinger, Daniel R. Cayan
1995, Journal of Climate (8) 606-623
Since the late 1940s, snowmelt and runoff have come increasingly early in the water year in many basins in northern and central California. This subtle trend is most pronounced in moderate-altitude basins, which are sensitive to changes in mean winter temperatures. Such basins have broad areas in which winter temperatures...
Graphical and PC-software analysis of volcano eruption precursors according to the Materials Failure Forecast Method (FFM)
Reinold R. Cornelius, Barry Voight
1995, Journal of Volcanology and Geothermal Research (64) 295-320
The Materials Failure Forecasting Method for volcanic eruptions (FFM) analyses the rate of precursory phenomena. Time of eruption onset is derived from the time of “failure” implied by accelerating rate of deformation. The approach attempts to fit data, Ω, to the...
Use of modern infrared thermography for wildlife population surveys
D.L. Garner, H.B. Underwood, W.F. Porter
1995, Environmental Management (19) 233-238
A commercially available thermal-infrared scanning system was used to survey populations of several wildlife species. The system's ability to detect species of different sizes in varying habitats relative to conventional survey methods, to differentiate between species in the same habitat, and the influence of environmental factors on operational aspects of...

The Hubble Space Telescope made systematic observations of the split comet P/Shoemaker-Levy 9 (SL9) (P designates a periodic comet) starting in July 1993 and continuing through mid-July 1994 when the fragments plunged into Jupiter's atmosphere. Deconvolutions of Wide Field Planetary Camera images indicate that the diameters of some...

1995, Circular 1123
The U.S. Geological Survey stream-gaging program provides streamflow data for a variety of purposes. The uses of streamflow data are described, and the growth of the stream-gaging program is related to legislation and the need to manage the Nation's water resources more effectively. A brief description is provided of the...
Quality of water in the alluvial aquifer and tributary alluvium of the Fountain Creek valley, southwestern El Paso County, Colorado, 1991-92
M.E. Lewis
1995, Water-Resources Investigations Report 94-4118
The alluvial aquifer in Fountain Creek Valley between Colorado Springs and Widefield is the source for several public water-supply systems. Since 1981, concentrations of dissolved nitrite plus nitrate as nitrogen (nitrate) have exceeded the drinking-water standard of 10 milligrams per liter in several areas of the aquifer. Water-quality data collected...
