Contrasts in Arctic shelf sea-ice regimes and some implications: Beaufort Sea versus Laptev Sea
E. Reimnitz, D. Dethleff, D. Nurnberg
1994, Marine Geology (119) 215-225
The winter ice-regime of the <80 km wide Alaskan Beaufort Sea shelf is characterized by compression and shearing, resulting in the formation of major grounded pressure ridge systems stabilizing the fast ice on the mid-shelf, and essentially no open-water areas. In contrast,...
Distribution and variability of nitrogen and phosphorus in the alluvial, High Plains, Rush Springs, and Blaine aquifers in western Oklahoma
C.J. Becker
1994, Open-File Report 94-41
Aquifers are the primary source of water for drinking and agricultural purposes in western Oklahoma. Health concerns about consuming nitrogen and an increased reliance on ground water for drinking necessitate a better understanding of the cause and effect of contamination from nutrients. The purpose of this project was to compile...

W. F. Krise, J. W. Meade, J.R. McClain
1994, Progressive Fish-Culturist (56) 207-210
Fingerling lake trout (Salvelinus namaycush) were reared for 64 d at three pressures of dissolved gases, expressed in relation to saturation values (▵P)–untreated (control) water, ▵P = 10 mm Hg; water treated by column degassing with air, ▵P = 9 mm Hg; and water treated with an oxygen injection system,...
Development of saline seeps in Southwestern United States
Kenneth S. Johnson
Anon, editor(s)
1994, Conference Paper, National Conference Publication - Institution of Engineers, Australia
Saline seeps are an increasingly serious problem in semi-arid regions of the southwestern United States. They result when excessive recharge of the shallow ground water in soils raises the water table locally to within one meter of the land surface, and the salinity of the shallow water is increased through...
Isotopic Approach to Soil Carbonate Dynamics and Implications for Paleoclimatic Interpretations
E. G. Pendall, J.W. Harden, S.E. Trumbore, O.A. Chadwick
1994, Quaternary Research (42) 60-71
The radiocarbon content and stable isotope composition of soil carbonate are best described by a dynamic system in which isotopic reequilibration occurs as a result of recurrent dissolution and reprecipitation. Depth of water penetration into the soil profile, as well as soil age, determines the degree of carbonate isotope reequilibration....

1994, Environmental Science & Technology (28) 2065-2073
Experiments in St. Kevin Gulch, an acid mine drainage stream, examined the coupling of hydrologic transport to chemical reactions affecting metal concentrations. Injection of LiCl as a conservative tracer was used to determine discharge and residence time along a 1497-m reach. Transport of metals downstream from inflows of acidic, metal-rich...

Hydrochemistry of the Mahomet Bedrock Valley Aquifer, East-Central Illinois: Indicators of recharge and ground-water flow
S.V. Panno, Keith C. Hackley, K. Cartwright, Chao-Li Liu
1994, Groundwater (32) 591-604
A conceptual model of the ground-water flow and recharge to the Mahomet Bedrock Valley Aquifer (MVA), east-central Illinois, was developed using major ion chemistry and isotope geochemistry. The MVA is a “basal” fill in the east-west trending buried bedrock valley composed of clean, permeable...
Suspended sediments of the modern Amazon and Orinoco rivers
R.H. Meade
1994, Quaternary International (21) 29-39
The Amazon and Orinoco Rivers are massive transcontinental conveyance systems for suspended sediment. They derive about 90% of their sediment from the Andes that support their western headwaters, transport it for thousands of kilometers across the breadth of the continent and deposit it in the coastal zones of the Atlantic....
Loma sp. salmonids from the Eastern United States: Associated lesions rainbow trout
P.T. Markey, V. S. Blazer, M. S. Ewing, K. M. Kocan
1994, Journal of Aquatic Animal Health (6) 318-328
A microsporidian of the genus Loma was noted in the gills of rainbow trout Oncorhynchus mykiss from a state hatchery (Buford Trout Hatchery) in Georgia. Mortalities of varying severity occur at this hatchery every fall, and the microsporidian was noted during an experiment from August 1991 to January...
Ground-water resources of Okeechobee County, Florida
L. A. Bradner
1994, Water-Resources Investigations Report 92-4166
Rapid population growth in Okeechobee County, Florida will increase future demand for potable water. Much of the ground water within the county is vulnerable to saltwater upconing or recharge water of poor-quality from the land surface. The surficial aquifer system within the county is a major source of domestic and...

R. L. Marella
1994, Open-File Report 93-364
According to the Florida Department of Environ- mental Protection, 5,100 wastewater treatment systems were in operation during 1990. Of this total, 72 percent were domestic wastewater facilities and 28 percent were industrial waste- water facilities. The number of wastewater systems inventoried for 1990 was 1,062 (systems that treated and discharged...

M.L. Davisson, T. S. Presser, R.E. Criss
1994, Geochimica et Cosmochimica Acta (58) 1687-1699
Tectonic compression has created abnormally high pressure on deep basinal fluids causing their expulsion from areally exposed Upper Cretaceous rock along the eastern margin of the California Coast ranges. The fluids emerge as near-neutral, perennial sodium chloride springs at high elevations with flow rates as high as 10 L per...

A. T. Rutledge, C.C. Daniel
1994, Groundwater (32) 180-189
The computer program, RORA, allows automated analysis of streamflow hydrographs to estimate ground-water recharge. Output from the program, which is based on the recession-curve-displacement method (often referred to as the Rorabaugh method, for whom the program is named), was compared to estimates of recharge obtained...

1994, Biological Mass Spectrometry (23) 437-439
The H2-H2O ambient-temperature equilibration technique for the determination of 2H/1H ratios in urinary waters from diabetic subjects provides improved accuracy over the conventional Zn reduction technique. The standard deviation, ~ 1-2???, is at least a factor of three better than that of the Zn reduction technique on urinary waters from...

Application of studies on the overboard placement of dredged sediments to the management of disposal sites
William Panageotou, Jeffrey Halka
McNair Clark E., editor(s)
1994, Conference Paper, International Conference on Dredging and Dredged Material Placement
From the mid 1960's until 1991, dredging and disposal occurred in the northern Chesapeake Bay without guidelines to maximize the capacity and to minimize the spread of the deposits beyond the disposal sites, particularly toward the navigation channel. Planning for future dredging projects is dependant upon the remaining site capacity...
