The use of marine electromagnetic conductivity as a tool in hydrogeologic investigations
P.B. Duran
1987, Groundwater (25) 160-166
Field procedures for collecting marine electromagnetic (EM) conductivity data were developed by the U.S. Geological Survey as part of a hydrogeologic investigation of the Delaware River shipping channel. Eighty miles of marine EM data collected along the border between Pennsylvania and New Jersey were used...
Partitioning potential fish yields from the Great Lakes
D.H. Loftus, C.H. Olver, Edward H. Brown, P.J. Colby, Wilbur L. Hartman, D.H. Schupp
1987, Canadian Journal of Fisheries and Aquatic Sciences (44) 417-424
We proposed and implemented procedures for partitioning future fish yields from the Great Lakes into taxonomic components. These projections are intended as guidelines for Great Lakes resource managers and scientists. Attainment of projected yields depends on restoration of stable fish communities containing some large piscivores that will use prey efficiently,...
Paint chip poisoning of Laysan albatross at Midway Atoll
L. Sileo, S.I. Fefer
1987, Journal of Wildlife Diseases (23) 432-437
Epizootic mortality occurred in Laysan albatross (Diomedea immutabilis) fledgings at Midway Atoll in 1983. Heavy metal toxicity from ingestion of weathered paint chips was one of the causes. Sick albatrosses were unable to retract their wings, causing a 'droop-wing' appearance. Five normal and 12 droop-winged fledglings were captured, killed, and...

Haraldur Sigurdsson, J.D. Devine, F.M. Tchua, F.M. Presser, M.K.W. Pringle, William C. Evans
1987, Journal of Volcanology and Geothermal Research (31) 1-16
On 15 August, 1984, a lethal gas burst issued from a submerged 96-m-deep crater in Lake Monoun in Cameroun, western Africa, killing 37 people. The event was associated with a landslide from the eastern crater rim, which slumped into deep water. Waters below 50 m are anoxic, dominated by high...

Unsaturated flow in a centrifugal field: Measurement of hydraulic conductivity and testing of Darcy's Law
John R. Nimmo, J. Rubin, D.P. Hammermeister
1987, Water Resources Research (23) 124-134
A method has been developed to establish steady state flow of water in an unsaturated soil sample spinning in a centrifuge. Theoretical analysis predicts moisture conditions in the sample that depend strongly on soil type and certain operating parameters. For Oakley sand, measurements of flux, water content, and matric potential...
GEOLOGICAL APPLICATIONS OF WELL LOGS: AN INTRODUCTORY BIBLIOGRAPHY AND SURVEY OF THE WELL LOGGING LITERATURE THROUGH SEPTEMBER 1986 ARRANGED BY SUBJECT.

This report includes over 1,350 individual citations as well as a first-author index. The purpose of this bibliography is twofold, 1) to provide a basic, first-stop resource on well logging which the non-specialist, i. e. , geoscientist, can consult and, 2) to provide a reference on geologic applications for the...

Radiocarbon and cation-radio ages for rock varnish on Tioga and Tahoe marainal boulders of Pine Creek, eastern Sierra Nevada, California, and their paleoclimatic implications
R.I. Dorn, B. D. Turrin, A.J.T. Jull, T.W. Linick, D.J. Donahue
1987, Quaternary Research (28) 36-49
Accelerator mass spectrometry 14C analyses of organic matter extracted from rock varnishes on morainal boulders yield limiting minimum ages for three crests of the Tioga glaciation. At Pine Creek in the eastern Sierra Nevada, varnish started to form on boulders of the outermost Tioga moraine before 19,000 yr B.P., and...
Geology of the Holocene surficial uranium deposit of the north fork of Flodelle Creek, northeastern Washington (USA)
S. Y. Johnson, J. K. Otton, D. L. Macke
1987, Geological Society of America Bulletin (98) 77-85
The north fork of Flodelle Creek drainage basin in northeastern Washington contains the first surficial uranium deposit to be mined in the United States. The uranium was leached from granitic bedrock and fixed in organic-rich pond sediments. The distribution of these pond sediments and, therefore, the uranium has been strongly...
A study of metal ion adsorption at low suspended-solid concentrations
Cecily C.Y. Chang, J.A. Davis, James S. Kuwabara
1987, Estuarine, Coastal and Shelf Science (24) 419-424
A procedure for conducting adsorption studies at low suspended solid concentrations in natural waters (<50 mg l−1) is described. Methodological complications previously associated with such experiments have been overcome. Adsorption of zinc ion onto synthetic colloidal titania (TiO2) was studied as a function...

P. Stone, V.M. Page, W. Hamilton, K. A. Howard
1987, Geology (15) 561-564
The upper part of the 7-km-thick McCoy Mountains Formation in southeastern California contains fossil angiosperm wood that closely resembles the genus Paraphyllanthoxylon, which is known only from strata of late Early Cretaceous and younger age. This wood, in conjunction with geologic field relations, supports...

H.T. Haselton Jr., R. A. Robie, B. S. Hemingway
1987, Geochimica et Cosmochimica Acta (51) 2211-2217
Heat capacities have been measured for synthetic hedenbergite (9–647 K), ferrobustamite (5–746 K) and CaFeSi2O6 glass (6–380 K) by low-temperature adiabatic and differential scanning calorimetry. The heat capacity of each of these structural forms of CaFeSiO6 exhibits anomalous behavior at low temperatures. The X-peak in the hedenbergite heat-capacity curve at 34.5 K...
