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...
Survival of duck plague virus in water from Lake Andes National Wildlife Refuge, South Dakota
Ken Wolf, C.N. Burke
1982, Journal of Wildlife Diseases (18) 437-440
An isolant of duck plague herpesvirus from the Lake Andes Refuge outbreak was seeded in raw and filter-decontaminated water from two locations on the refuge, held at 4 C, and assayed for infectivity intermittently over a period of 2 mo. From an initial level of about 105 PFU per ml, infectivity...

Implementation of digital subtraction angiography with a synchrotron x-ray beam

1982, IEEE Transactions on Nuclear Science (29) 441-446
The intense synchrotron radiation produced by wiggler magnets at electron storage rings provides a new source of x-rays highly suited to iodine K-edge digital subtraction angiography. The monochromaticity and tunability provide maximum sensitivity to intraarterial iodine and virtually eliminate contrast due to soft tissue and bone. Visualization of arteries, in...

A review of remote sensing and grasslands literature
G. Gray Tappan, H. C. Kinsler
1982, Cooperator Report E82-10277
Studies between 1971 and 1980 dealing with remote sensing of rangelands/grasslands in the multispectral band are summarized and evaluated. Vegetation and soil reflectance properties are described. In the majority of the studies, the effect of the reflectance of green rangelands vegetation on the reflectance from the total scene is the...
Paleomagnetic study of some Cretaceous and Tertiary sedimentary rocks of the Klamath Mountains province, California
Edward A. Mankinen, William P. Irwin
1982, Geology (10) 82-87
Paleomagnetic investigation of Cretaceous outliers and Tertiary sedimentary strata of the Klamath Mountains province, and of onlapping Cretaceous strata, has shown the rocks to be largely remagnetized. Samples studied are from the Upper Jurassic to Upper Cretaceous Great Valley sequence, Upper Cretaceous Hornbrook Formation, Eocene Montgomery Creek Formation, and Oligocene(?)...

Voyager 2 photography has complemented that of Voyager I in revealing many additional characteristics of Saturn and its satellites and rings. Saturn's atmosphere contains persistent oval cloud features reminiscent of features on Jupiter. Smaller irregular features track out a pattern of zonal winds that is symmetric about...
A late Pleistocene glacial chronology for the southern Brooks Range: Stratigraphic record and regional significance
T. D. Hamilton
1982, GSA Bulletin (93) 700-716
Radiocarbon dates from 11 measured sections in the Koyukuk region provide a chronology of the last Pleistocene glaciation. Glaciers were advancing strongly by 24,000 yr ago; they built moraines near the south flank of the Brooks Range, retreated briefly about 22,000 to 20,000 yr B.P., then readvanced at least one...

Diverse basalt types from Loihi seamount, Hawaii
James G. Moore, D. A. Clague, W. R. Normark
1982, Geology (10) 88-92
Loihi seamount is the southeasternmost active volcano in the Hawaiian-Emperor volcanic chain. The seamount is considered representative of the early phase of Hawaiian volcanism because of its youth, small size, and location near the melting anomaly. Seventeen dredge stations recovered transitional basalt, alkalic basalt, and basanite, in addition to the...
Ancient plate boundaries in the Bering Sea region
M. S. Marlow, Alan K. Cooper, David W. Scholl, H. McLean
1982, Geological Society, London, Special Publications (10) 201-211
Plate tectonic models of the Bering Sea suggest that the abyssal Bering Sea Basin is underlain by oceanic crust, a supposition supported by refraction and magnetic data. The oceanic crust is thought to be a remnant of the Kula(?) plate that was isolated within what is now the Bering...

Hydrologic data from monitoring of saline-water intrusion in the Cape Coral area, Lee County, Florida
Daniel J. Fitzpatrick
1982, Open-File Report 82-772
As a result of declining water levels and saline-water intrusion in the Cape Coral area, the U.S. Geological Survey in cooperation with the City of Cape Coral established a monitoring well network in Cape Coral and adjacent areas in 1978-79. The network was designed to provide indication of lateral movement...
