On conducting the modified ‘Slug’ test in tight formations
C.E. Neuzil
1982, Water Resources Research (18) 439-441
The method introduced by Bredehoeft and Papadopulos (1980) for conducting a modified ‘slug’ test in tight formations does not assure the condition of approximate equilibrium necessary at the start of the test. In addition, compressibility in the shut-in well can be significantly larger than the compressibility of water, which Bredehoeft...
Organochlorine residues and shell thinning in Oregon seabird eggs
Charles J. Henny, Lawrence J. Blus, Richard M. Prouty
1982, Murrelet (63) 15-21
A single egg was collected at 62 nests of 10 seabird species from Oregon in 1979. The eggs were analyzed for organochlorine contaminants; contemporary shell thickness was compared with eggshells collected during earlier time periods. Concentrations of DDE and PCB's in 1979 were generally low with the most contaminated species...
Volatilization of ketones from water
R. E. Rathbun, D. Y. Tai
1982, Water, Air, & Soil Pollution (17) 281-293
The overall mass-transfer coefficients for the volatilization from water of acetone, 2-butanone, 2-pentanone, 3-pentanone, 4-methyl-2-pentanone, 2-heptanone, and 2-octanone were measured simultaneously with the oxygen-absorption coefficient in a laboratory stirred water bath. The liquid-film and gas-film coefficients of the two-film model were determined for the ketones from the overall coefficients,...
Hematology of the West Indian manatee (Trichechus manatus)
W. Medway, D.J. Black, G. B. Rathbun
1982, Veterinary Clinical Pathology (11) 11-15
Hemograms on blood obtained from 10 clinically normal West Indian Manatees (Trichechus manatus) were studied. The red cells were large and in lower number than in most terrestrial species. The manatee does not have a neutrophil as is present in most species, but it has a heterophil whose granules stain...
Habitat models for land-use planning: assumptions and strategies for development
Adrian H. Farmer, Michael J. Armbruster, James W. Terrell, Richard L. Schroeder
1982, Book, Transactions of the Forty-seventh North American Wildlife and Natural Resources Conference: Population pressures and natural resource management needs
Wildlife managers have long recognized that management goals must be constrained by the availability and suitability of habitat. This recognition, combined with ever increasing land development pressures, has resulted in environmental legislation emphasizing systematic approaches to collection and analysis of habitat information. Wildlife planners have responded with a...
Lumber spill in central California waters: Implications for oil spills and sea otters
G.R. VanBlaricom, R.J. Jameson
1982, Science (215) 1503-1505
A large quantity of lumber was spilled in the ocean off central California during the winter of 1978, and it spread through most of the range of the threatened California sea otter population within 4 weeks. The movement rates of lumber were similar to those of oil slicks observed elsewhere....
Mid-Paleozoic age of the Roberts thrust unsettled by new data from northern Nevada
Keith B. Ketner, Fred J. Smith Jr.
1982, Geology (10) 298-303
The Roberts thrust is a major thrust in Nevada on which Ordovician to Devonian siliceous facies rocks were carried more than 80 km eastward over contemporaneous carbonate facies. For more than two decades, a mid-Paleozoic age for this structure has been widely accepted. The bases for dating the thrust are...
Molecular size of aquatic humic substances
E.M. Thurman, R.L. Wershaw, Ronald L. Malcolm, D.J. Pinckney
1982, Organic Geochemistry (4) 27-35
Aquatic humic substances, which account for 30 to 50% of the organic carbon in water, are a principal component of aquatic organic matter. The molecular size of aquatic humic substances, determined by small-angle X-ray scattering, varies from 4.7 to 33 Å in their radius of gyration, corresponding to a molecular...
Optimum nonparametric estimation of population density based on ordered distances
S.A. Patil, J.L. Kovner, Kenneth P. Burnham
1982, Biometrics (38) 243-248
The asymptotic mean and error mean square are determined for the nonparametric estimator of plant density by distance sampling proposed by Patil, Burnham and Kovner (1979, Biometrics 35, 597-604. On the basis of these formulae, a bias-reduced version of this estimator is given, and its specific form is determined...
Accumulation of 14C-naphthalene in the tissues of redhead ducks fed oil-contaminated crayfish
I. Barry Tarshis, Barnett A. Rattner
1982, Archives of Environmental Contamination and Toxicology (11) 155-159
Crayfish, artificially contaminated with14C-naphthalene-5% water-soluble fraction of No. 2 fuel oil, were force-fed to one-year-old redhead ducks to determine the accumulation of petroleum hydrocarbons. The relative distribution of carbon-14 activity in the gall bladder containing bile, and fat were similar, and significantly greater (P < 0.05) than the activity in...
Use of blood levels to infer carcass levels of contaminants
Gary L. Hensler, William C. Stout
1982, Archives of Environmental Contamination and Toxicology (11) 235-238
Inferences may be made about the carcass levels of a contaminant based on the contaminant level in blood samples. A method is given for comparing such populations that utilizes bivariate normal distributions and their principal axes, thereby avoiding a dilemma arising from the use of regression techniques. Confidence intervals and...
Ingestion of petroleum by breeding mallard ducks: Some effects on neonatal progeny
J. Gorsline, W. N. Holmes
1982, Archives of Environmental Contamination and Toxicology (11) 147-153
Breeding female mallard ducks consuming petroleum-contaminated food show significant induced increases in the naphthalene-metabolizing properties of microsomes prepared from their livers. Food contaminated with South Louisiana crude oil was more potent than food contaminated with similar concentrations of Prudhoe Bay crude oil and in each instance food contaminated with 3%...
Age determination of late Pleistocene marine transgression in western Alaska
Barney J. Szabo
1982, Marine Geology (46) M1-M8
Dating molluscs from sediments representing the Kotzebuan marine transgression in Alaska yields an average uranium-series age of 104,000 ± 22,000 yrs B.P. This and other selected Pleistocene marine deposits of western Alaska are tentatively correlated with radiometrically dated units of eastern Baffin Island, Arctic Canada....
Cenozoic silicoflagellates from offshore Guatemala, Deep Sea Drilling Project Site 495
David Bukry
1982, Initial Reports of the D.S.D.P. (67) 425-445
Diverse lower Miocene to Pleistocene silicoflagellate assemblages occur at Deep Sea Drilling Project Site 495, but many samples are dominated by one or two taxa. Low-latitude zonation can be applied throughout. Cool-indicating Distephanus speculum s. ampl. is only abundant in the upper Miocene; however, relative paleotemperature values (Ts) suggest temperature...

J. Aubouin, Roland E. von Huene, M. Baltuck, Robert Arnott, J. Bourgois, M.V. Filewicz, Keith A. Kvenvolden, Barry Leinert, Tom McDonald, Kristin McDougall-Reid, Y. Ogawa, Elliot Taylor, Barbara Winsborough
