Trends in ground-water levels in Wisconsin through 1981
R.M. Erickson, R. D. Cotter
1983, Wisconsin Geological & Natural History Survey Information Circular 43
Hydrographs of ground-water levels in Wisconsin display fluctuations in the potentiometric surface of confined and unconfined aquifers. The graphs are plotted from periodic (weekly or monthly) measurements and from continuous recording gage records. Two hundred and ten hydrographs having periods of record of at least 5 years between 1934 and...
Reconnaissance of ground water in vicinity of Wichita Mountains southwestern Oklahoma
John S. Havens
1983, Circular 85
Urbanization and industrial growth have increased demands on water supplies in the vicinity of the Wichita Mountains in southwestern Oklahoma. The principal city, Lawton, uses surface water, supplemented by small quantities of ground water from the Arbuckle Group (Cambrian-Ordovician), for industrial and recreational use. During periods of drought, surface-water supplies...
Geohydrologic framework of the Roswell ground-water basin, Chaves and Eddy Counties, New Mexico
G. E. Welder
1983, Technical Report 42
This report describes the geohydrology of the Roswell ground-water basin and shows the long-term hydrostatic-head changes in the aquifers. The Roswell ground-water basin consists of a carbonate artesian aquifer overlain by a leaky confining bed, which, in turn is overlain by an alluvial water-table aquifer. The water-table aquifer is hydraulically...
Reconnaissance of the quality of surface water in the Weber River basin, Utah
Kendall R. Thompson
1983, Technical Publication 76
This report on the reconnaissance of surface-water quality in the Weber River basin was prepared by the U.S. Geological Survey in cooperation with the Utah Department of Natural Resources, Division of Water Rights. The purposes of the reconnaissance were: (1) To obtain information on the general inorganic chemical characteristics of...
Multiwavelength EDM measurements in southern California
Larry E. Slater, Art McGarr, John O. Langbein, Mark F. Linker
1983, Tectonophysics (97) 39-39
We installed a precise geodetic network along the San Andreas fault near Pearblossom, California in November, 1980. The network is within the region frequently referred to as the "Palmdale Uplift" and consists of 13 lines radiating from a central benchmark. The lines range in length from 3.2 to 8.1 km...
Land use and land cover digital data
Robin G. Fegeas, Robert W. Claire, Stephen C. Guptill, K. Eric Anderson, Cheryl A. Hallam
1983, Open-File Report 82-22
The discipline of cartography is undergoing a number of profound changesthat center on the emerging influence ofdigital manipulation and analysis ofdata for the preparation of cartographic materials and for use in geographic information systems. Operational requirements have led to the development by the USGS National Mapping Division of several documents...
Additions of nutrients and major ions by the atmosphere and tributaries to nearshore waters of northwestern Lake Huron
Bruce A. Manny, R.W. Owens
1983, Journal of Great Lakes Research (9) 403-420
Nutrient additions by the atmosphere and six tributaries to nearshore waters of northwestern Lake Huron were measured at weekly intervals from August 1975 to July 1976. The atmosphere contributed 43% of the nitrogen (N) and 10% of the phosphorus (P) that was added during the year. The 1975–76 atmospheric loading...
13C NMR spectral characterization of epimeric rotenone and some related tetrahydrobenzopyranofurobenzopyranones
S. L. Abidi, M.S. Abidi
1983, Journal of Heterocyclic Chemistry (20) 1687-1692
The 13C nuclear magnetic resonance (nmr) spectra of epimers of rotenone and four 12a-hydroxy-analogues were examined to determine the stereochemical effect of the B/C ring fusion involving the 6a- and 12a-carbon centers. Chemical shift differences between the epimeric carbon resonances of cis- and trans-6a,12a-compounds were notably larger than those of...
High-performance liquid chromatography of quinoidal imminium compounds derived from triphenylmethanes
S. L. Abidi
1983, Journal of Chromatography (255) 101-114
A series of eleven p-aminotriphenylmethane dyes have been studied by high-performance liquid chromatography (HPLC). The combined use of HPLC and spectrophotometry permits specific detection of these compounds in the visible range around 600 nm. As the high affinity of the imminium cations for the active sites of the hydrocarbonaceous stationary...
The use of albendazole for the treatment of trematodiasis in two tree shrews (Tupala glis)
B.A. Beehler, B.N. Tuggle
1983, Journal of Zoo Animal Medicine (14) 61-63
Albendazole is a broad-spectrum anthelmintic of the benzimidazole group which has been tested in several rodents and domestic animals. Albendazole has been used effectively to treat trematodes in sheep, cattle, dogs, and cats. The use of this anthelmintic in exotic small mammals has not been reported to the authors' knowledge....
Effects on birds of fenthion aerial application for mosquito control
L.R. DeWeese, L. C. McEwen, L.A. Settimi, R.D. Deblinger
1983, Journal of Economic Entomology (76) 906-911
Effects on birds of an aerial application of fenthion, a potent organophosphorus cholinesterase (ChE)-inhibiting insecticide, were assessed on four study sites 1.8 to 3.6 km2 in size. These sites were located within 121.5 km2 of wet meadows treated with 47 g of fenthion (AI) per ha in ultra-low-volume formulation. Assessment methods were...
Distribution and ecology of marine turtles in waters off the southeastern United States
T. H. Fritts, W. Hoffman, M.A. McGehee
1983, Journal of Herpetology (17) 327-344
Aerial surveys of marine waters up to 222 km from shore in the Gulf of Mexico and nearby Atlantic Ocean suggest that marine turtles are largely distributed in waters less than 100 m in depth. The loggerhead turtle (Caretta caretta) was observed nearly 50 times as often in waters off...
Effects of dietary ABATE® on reproductive success, duckling survival, behavior, and clinical pathology in game-farm mallards
J. Christian Franson, James W. Spann, Gary Heinz, Christine M. Bunck, Thair Lamont
1983, Archives of Environmental Contamination and Toxicology (12) 529-534
Forty-four pairs of game-farm mallards (Anas platyrhynchos) were fed ABATE® 4E (temephos) to yield 0, 1, or 10 ppm ABATE® beginning before the initiation of lay, and terminating when ducklings were 21 days of age. The mean interval between eggs laid was greater for hens fed 10 ppm...
Feeding habitats of nesting wading birds: Spatial use and social influences
R. Michael Erwin
1983, The Auk (100) 960-970
In an effort to relate social interactions to feeding-habitat use, I observed six species of wading birds near a major colony site in coastal North Carolina. Three spatial scales of habitat use were considered: the general orientation to and from the colony (coarsest level), the habitat "patch," and (at the...
DDE in brown and white fat of hibernating bats
D. R. Clark Jr., A. J. Krynitsky
1983, Environmental Pollution (Series A) (31) 287-299
Samples of brown and white fat from hibernating bats (big brown bat, Eptesicus fuscus; little brown bat, Myotis lucifugus; and eastern pipistrelle, Pipistrellus subflavus) collected in western Maryland, USA, were analysed to determine lipid and DDE content. Amounts of brown fat, expressed as percentages of...
Year and age effects on residues of dieldrin and heptachlor in dead gray bats, Franklin County, Missouri— 1976, 1977, and 1978
D. R. Clark Jr., C.M. Bunck, E. Cromartie, R. K. LaVal
1983, Environmental Toxicology and Chemistry (2) 387-393
Dead gray bats (Myotis grisescens) containing lethal concentrations of dieldrin were found beneath a maternity roost in Bat Cave Nos. 2 and 3, Franklin County, Missouri, in 1976, 1977 and 1978. Whereas residues of dieldrin, DDE [1,1-dichloro-2,2-bis(p-chlorophenyl)ethylene] and PCB polychlorinated biphenyls in bats appeared not to change significantly over the...
