R.O. Fournier, B.B. Hanshaw
1986, Applied Geochemistry (1) 189-197
The chemical and isotopic compositions of hot springs in the San Marcos region of Guatemala are internally consistent with a hydrologic model in which a deep 240°C reservoir and one or more shallow 195–200°C reservoirs are present. Variations in hot-spring water...

W. F. Krise, L. Bulkowski-Cummings, A.D. Shellman, K. A. Kraus, R. W. Gould
1986, Progressive Fish-Culturist (48) 95-100
Various techniques for eliminating the clumping of newly spawned walleye eggs (Stizostedion vitreum) were evaluated by measuring hatch, growth, and survival. Percent hatch was highest (83%) in egg groups water hardened in 0.01% protease solution. Other water‐hardening techniques tested were: (1) continuous stirring; (2) 250 mg/L tannic acid solution; and...

Schuster Robert L., editor(s)
1986, Conference Paper
The collapse of the north face of Mount St. Helens on May 18, 1980, and the debris avalanche that resulted blocked outflow from Spirit Lake and Coldwater and South Fork Castle Creeks. Spirit Lake began to increase in size and lakes began to form in the canyons of Coldwater and...
PERSPECTIVE ON LANDSLIDE DAMS.
Robert L. Schuster, John E. Costa
Schuster Robert L., editor(s)
1986, Conference Paper
The most common types of mass movements that form landslide dams are rock and soil slumps and slides; mud, debris, and earth flows: and rock and debris avalanches. The most common initiation mechanisms for dam-forming landslides are excessive rainfall and snow melt, and earthquakes. Most landslide dams are remarkable short-lived....

Ground-water resource assessment of the Montauk area, Long Island, New York
K. R. Prince
1986, Water-Resources Investigations Report 85-4013
The water resources of the Montauk area were investigated from October 1980 through September 1983 to assess the availability of fresh groundwater. The principal aquifer, which consists of fine- to coarse-grained stratified glacial drift, is the sole source of freshwater. The freshwater/saltwater interface lies as much as 150 ft below...
Limitations in the use of commercial humic acids in water and soil research
Ronald L. Malcolm, P. MacCarthy
1986, Environmental Science & Technology (20) 904-911
Seven samples of commercial "humic acids", purchased from five different suppliers, were studied, and their characteristics were compared with humic and fulvic acids isolated from streams, soils, peat, leonardite, and a dopplerite sample. Cross-polarization and magic-angle spinning 13C NMR spectroscopy clearly shows pronounced differences between the commercial materials and all...

Urbonas BenRoesner Larry A., editor(s)
1986, Conference Paper
The United States was divided into three regions, on the basis of mean annual rainfall, to decrease the variability in storm-runoff constituent loads and to improve regression relations with basin and climatic characteristics. Multiple-regression analyses, in progress, are being refined to determine the best regression models for each of the...
EFFECTS OF DRAIN ENVELOPE AND SLOPE ON PERFORMANCE OF A DRAINAGE-SUBIRRIGATION SYSTEM.
Marjorie S. Davenport, R.W. Skaggs
1986, Conference Paper, Paper - American Society of Agricultural Engineers
A field study was conducted to determine the effect of fabric wrap envelope and drain slope on the performance of a combination drainage and subirrigation system. Data were analyzed by examining relationships between flow rate and midpoint water table elevations. An entry resistance was defined and its value for each...

Michael L. Merritt
1986, Conference Paper
Subsurface freshwater storage has been operationally tested at seven sites in central and south Florida. Injection was into a high chloride water aquifer at six sites, and into a high sulfate water aquifer at the seventh. Recovery efficiency has ranged from 0 to 75 percent in high chloride water aquifers,...

P.R. Klock, G.K. Czamanske, M. Foose, J. Pesek
1986, Chemical Geology (54) 157-162
Six analytical techniques for the selective chemical dissolution of sulfides are compared with the purpose of defining the best method for accurately determining the concentration of sulfide-bound nickel. Synthesized sulfide phases of known elemental content, mixed with well-analyzed silicates, were used to determine the relative and absolute efficiency, based on...
Estimation of distributional parameters for censored trace level water quality data: 1. Estimation techniques
Robert J. Gilliom, Dennis R. Helsel
1986, Water Resources Research (22) 135-146
A recurring difficulty encountered in investigations of many metals and organic contaminants in ambient waters is that a substantial portion of water sample concentrations are below limits of detection established by analytical laboratories. Several methods were evaluated for estimating distributional parameters for such censored data sets using only uncensored observations....
Application of seismic refraction methods in groundwater modeling studies in New England (USA)
F.P. Haeni
1986, Geophysics (51) 236-249
Seismic refraction studies were conducted over unconfined glacial aquifers in New England to determine: 1) depth of the underlying bedrock; 2) depth of the water table; 3) saturated thickness of the aquifer in areas not accessible to heavy drilling equipment; 4) areas where thick, unsaturated sediments overlie thickly saturated parts...
Paleontology and deposition of the Phosphoria Formation.
B. R. Wardlaw, J.W. Collinson
1986, Contributions to Geology - University of Wyoming, Laramie (24) 107-142
The Phosphoria Formation and related rocks were deposited in an interior sag basin developed in the Cordilleran miogeocline of western North America. Deposition can be characterized as a fringing bank complex on a carbonate ramp. Conodont-brachiopod biostratigraphy provides a sufficient relative time framework for correlation of the many units. These...
A ground-water mixing model for the origin of the Imini manganese deposit (Cretaceous) of Morocco
E. R. Force, W. Back, E.C. Spiker, L.P. Knauth
1986, Economic Geology (81) 65-79
Three beds of manganese oxide ore in a 10 m-thick dolomite unit are associated with diagenetic features, and, are accordingly also diagenetic in their present aspect. Whether primary or introduced, the Mn mineralogy is attributed to reactions between fresh and saline ground-waters as the zone of mixing passed through the...

Carl J. Markon, Stephen S. Talbot
1986, Conference Paper, Technical Papers of the American Society of Photogrammetry, Fall Technical Meeting
Landsat-derived land cover maps and associated elevation, slope, and aspect class maps were produced for the Innoko National Wildlife Refuge (3,850,000 acres; 1,555,095 hectares) in northwestern Alaska. These maps and associated digital data products are being used by the U. S. Fish and Wildlife Service for wildlife management, research, and...
PHREATOPHYTE WATER USE ESTIMATED BY EDDY-CORRELATION METHODS.
H. L. Weaver, E.P. Weeks, G. S. Campbell, D.I. Stannard, B.D. Tanner
1986, Conference Paper
Water-use was estimated for three phreatophyte communities: a saltcedar community and an alkali-Sacaton grass community in New Mexico, and a greasewood rabbit-brush-saltgrass community in Colorado. These water-use estimates were calculated from eddy-correlation measurements using three different analyses, since the direct eddy-correlation measurements did not satisfy a surface energy balance. The...
Oxygen isotope compositions of selected laramide-tertiary granitoid stocks in the Colorado Mineral Belt and their bearing on the origin of climax-type granite-molybdenum systems
J. L. Hannah, H. J. Stein
1986, Contributions to Mineralogy and Petrology (93) 347-358
Quartz phenocrysts from 31 granitoid stocks in the Colorado Mineral Belt yield ??18O values less than 10.4???, with most values between 9.3 and 10.4???. An average magmatic value of about 8.5??? is suggested. The stocks resemble A-type granites; these data support magma genesis by partial melting of previously depleted, fluorine-enriched,...

J.T. Turk
1986, Water, Air, & Soil Pollution (27) 237-242
Replicate pH measurements in three dilute lakes made during extreme conditions indicate that pH can be measured in the field with a variance due to measurement error of 0.005 unit. Error of the field technique in measuring the pH of dilute solutions in the laboratory ranges from less than 0.01...
