Decreased survival of rainbow trout exposed to no. 2 fuel oil caused by sublethal preexposure
B. L. Steadman, W. A. Stubblefield, T. W. Lapoint, H.L. Bergman, M.S. Kaiser
1991, Environmental Toxicology and Chemistry (10) 355-363
Rainbow trout (Oncorhynchus mykiss) were exposed for 21 d to sublethal levels of No. 2 fuel oil (2FO). The four exposure concentrations ranged from 12 to 100 mg/L 2FO dispersed in water and resulted in 0 to 12% mortality. Following this exposure period (preexposure) the ability of preexposed trout to...

Degassing and differentiation in subglacial volcanoes, Iceland
James G. Moore, L. C. Calk
1991, Journal of Volcanology and Geothermal Research (46) 157-180
Within the neovolcanic zones of Iceland many volcanoes grew upward through icecaps that have subsequently melted. These steep-walled and flat-topped basaltic subglacial volcanoes, called tuyas, are composed of a lower sequence of subaqueously erupted, pillowed lavas overlain by breccias and hyaloclastites produced by phreatomagmatic explosions in shallow water, capped by...
Microbial production of organic acids in aquitard sediments and its role in aquifer geochemistry
P.B. McMahon, F. H. Chapelle
1991, Nature (349) 233-235
Microbial activity in aquifers plays an important part in the chemical evolution of ground water1–5. The most important terminal electron-accepting microbial processes in deeply buried anaerobic aquifers are iron reduction, sulphate reduction and methanogenesis5–8, each of which requires simple organic compounds or hydrogen (H2) as electron donors. Until now, the...
Simulation of the effects of proposed tide gates on circulation, flushing, and water quality in residential canals, Cape Coral, Florida
Carl R. Goodwin
1991, Open-File Report 91-237
Decades of dredging and filling of Florida's low-lying coastal wetlands have produced thousands of miles of residential tidal canals and adjacent waterfront property. Typically, these canals are poorly flushed, and over time, accumulated organic-rich bottom materials, contribute to an increasingly severe degraded water quality. One-dimensional hydrodynamic and constituent-transport models were...
Preliminary analysis of the hydrologic and geochemical controls on acid‐neutralizing capacity in two acidic seepage lakes in Florida
Curtis D. Pollman, T. M. Lee, William J. Andrews, L. A. Sacks, S.A. Gherini, R.K. Munson
1991, Water Resources Research (27) 2321-2335
In late 1988, parallel studies of Lake Five‐O (pH 5.14) in the Florida panhandle and Lake Barco (pH 4.50) in north central Florida were initiated to develop hydrologic and major ion budgets of these lakes as part of an overall effort to improve understanding of the hydrologic, depositional, and biogeochemical...

Assessing the solubilities and reaction kinetics of aluminous minerals in soils
Howard M. May, D. Kirk Nordstrom
1991, Book chapter, Solid acidity
The use of chemical thermodynamics and reaction kinetics is necessary to quantitatively model the transformation of aluminous minerals and their dissolved constituents in soils and other geochemical systems. Soils are thermodynamically open systems subject to atmospheric and biological forces and do not attain overall thermodynamic equilibrium with respect to either...

User's guide to the wetland creation/restoration data base, version 2
Lee Miller, Gregor T. Auble, Keith Schneller-McDonald
1991, Book
Wetland creation or restoration projects are frequently proposed as mitigation for unavoidable wetland losses, as components of wetland enhancement programs, and as tools to accomplish specific objectives such as waterfowl production or flood control. There is considerable controversy concerning the effectiveness of such projects as well as the most appropriate...
Evaluation of unsaturated zone air permeability through pneumatic tests
Arthur L. Baehr, Marc F. Hult
1991, Water Resources Research (27) 2605-2617
Predicting the steady state distribution of air pressure in the unsaturated zone resulting from a pneumatic test provides a method for determining air-phase permeability. This technique is analogous to the inverse problem of well hydraulics; however, air flow is more complicated than ground water flow because of air compressibility, the...
Electromagnetic terrain conductive and ground penetrating radar investigation at and near the Ciba-Geigy Superfund site, Ocean County, New Jersey: quality control assurance plan and results
Gary J. Barton, Tamara Ivahnenko
1991, Book, Proceedings of the Symposium on the Application of Geophysics to Engineering and Environmental Problems
Ground water is the principal source of drinking water in the vicinity of the Ciba-Geigy Superfund site near Toms River, Ocean County, New Jersey. The presence of earlier identified point sources of organic-compound and, to a lesser extent, metals contamination dt the Ciba-Geigy Toms River Chemical Company Plant has resulted-in severe degradation of ground-water quality...

Riparian vegetation of the Black Canyon of the Gunnison River, Colorado: composition and response to selected hydrologic regimes based on a direct gradient assessment model
Gregor T. Auble, Jonathan M. Friedman, Michael L. Scott
1991, Report
The Black Canyon of the Gunnison National Monument is located along the Gunnison River on the western slope of the Rocky Mountains in Montrose County, Colorado. The canyon is narrow because it is cut into resistant pre-Cambrian gneiss: it has a maximum depth of 900m and a minimum width of...

Late Quaternary stratigraphy and depositional history of the Long Island Sound basin
Ralph S. Lewis, Janet Radway Stone
1991, Journal of Coastal Research (11) 1-23
The stratigraphy of Late Quaternary geologic units beneath Long Island Sound (LIS) is interpreted from 3,500 km of high-resolution, seismic-reflection profiles supplemented by vibracore data. Knowledge gained from onshore regional geologic studies and previous offshore investigations is also incorporated in these interpretations. Glacial deposits overlie and nearly fill an Inner Lowland...

Isotropic fractination of leaf water during transpiration is influenced by both equilibrium and kinetic factors. Previous workers have predicted that the influence of each factor varies depending upon the path of water loss,m whether centralized through stomata, or diffuse through the cuticle. We studied the relationship between the...

The western part of the conterminous United States is often thought of as being a desert without any large bodies of water. In the desert area of western Utah, however, lies Great Salt Lake, which in 1986 covered approximately 2,300 square miles and contained 30 million acre-feet of water (an...
