Site 765: Sediment Lithostratigraphy
Leg 123 Shipboard Scientific Party
1990, Proceedings of the Ocean Drilling Program: Initial Reports (123) 76-94
A 935-m-thick succession of Quaternary through Lower Cretaceous sediments was recovered at Site 765 (Fig. 10). A single core of Quaternary sediment was obtained from Hole 765A; drilling terminated and a new hole was drilled in an attempt to establish the mud line. Quaternary through middle Miocene sediments were cored...

1990, Biological Report 90(12)
Sea otters (Enhydra lutris) that were captured in western Prince William Sound (PWS) or the Gulf of Alaska, treated, and held in captivity at the temporary rehabilitation centers established in response to the T/V Exxon Valdez oil spill were instrumented with radio transmitters, released into eastern PWS, and monitored by...
Origin and migration of hydrocarbon gases and carbon dioxide, Bekes Basin, southeastern Hungary
J.L. Clayton, C. W. Spencer, I. Koncz, A. Szalay
1990, Organic Geochemistry (15) 233-247
The Békés Basin is a sub-basin within the Pannonian Basin, containing about 7000 m of post-Cretaceous sedimentary rocks. Natural gases are produced from reservoirs (Precambrian to Tertiary in age) located on structural highs around the margins of the basin. Gas composition and stable carbon isotopic data indicate that most of...
Chironomidae of the southeastern United States: a checklist of species and notes on biology, distribution, and habitat
Patrick L. Hudson, David R. Lenat, Broughton A. Caldwell, David Smith
1990, Fish and Wildlife Research 7
We provide a current listing of the species of midges (Diptera:Chironomidae) in the southeastern United States (Alabama, Florida, Georgia, North Carolina, South Carolina, and Tennessee). This checklist should aid research on this group of insects, which have often proved useful in the assessment of water quality. We document each species'...

Evaluation of ground-water recharge along the Gila River as a result of the flood of October 1983, in and near the Gila River Indian Reservation, Maricopa and Pinal Counties, Arizona
A.D. Konieczki, S. R. Anderson
1990, Water-Resources Investigations Report 89-4148
Flow in the Gila River from the flood of October 1983 infiltrated the stream channel and recharged the groundwater system along the Gila River floodplain from Ashurst-Hayden Dam to the confluence with the Salt River. Changes in groundwater levels from January 1983 to March 1984 confirmed the occurrence of recharge...

T. W. Custer, P. C. Frederick
1990, Condor (92) 772-775
The authors' objective was to describe egg size in relation to laying order for Great Egrets (Casmerodius albus ), Snowy Egrets (Egretta thula ), and Black-crowned Night-Herons (Nycticorax nycticorax ) in a southern Texas colony and Great Egrets in a southern Florida colony. Based on egg-size patterns in...
Small domes on Venus: Probable analogs of Icelandic lava shields
James B. Garvin, Richard S. Williams Jr.
1990, Geophysical Research Letters (17) 1381-1384
On the basis of observed shapes and volumetric estimates, we interpret small, dome-like features on radar images of Venus to be analogs of Icelandic lava-shield volcanoes. Using morphometric data for venusian domes in Aubele and Slyuta (in press), as well as our own measurements of representative dome volumes and areas...
Geotechnical engineering for ocean waste disposal. An introduction
Homa J. Lee, Kenneth R. Demars, Ronald C. Chaney
Demars Kenneth R.Chaney Ronald C., editor(s)
1990, Conference Paper, ASTM Special Technical Publication
As members of multidisciplinary teams, geotechnical engineers apply quantitative knowledge about the behavior of earth materials toward designing systems for disposing of wastes in the oceans and monitoring waste disposal sites. In dredge material disposal, geotechnical engineers assist in selecting disposal equipment, predict stable characteristics of dredge mounds, design mound...
Woodford shale in the Anadarko basin: Could it be another 'Bakken type' horizontal target?
Timothy C. Hester, James W. Schmoker, Howard L. Sahl
1990, Oil & Gas Journal (88) 73-78
The Woodford shale is one of several organic rich "black" shales of late Devonian and early Mississippian age present in basins of the North American craton. Where thermally mature, these black shales are economically important as hydrocarbon source rocks. The Woodford shale is widely regarded as a major source rock...
Organic geochemical studies of the transformation of gymnospermous xylem during peatification and coalification to subbituminous coal
Patrick G. Hatcher, H. E. Lerch III, T.V. Verheyen
1990, International Journal of Coal Geology (16) 193-196
Organic geochemical investigations of peatified and coalified xylem from gymnosperms have provided useful information on the organic transformational processes collectively known as coalification. The combined use of solid-state 13C nuclear magnetic resonance (NMR) and pyrolysis/gas chromatography/mass spectrometry (py/gc/ms) has allowed us to...
Channel-changing processes on the Santa Cruz River, Pima County, Arizona, 1936-86
John T.C. Parker
French Richard H., editor(s)
1990, Conference Paper, Hydraulics/Hydrology of Arid Lands
Lateral channel change on the mainly ephemeral Santa Cruz River, Pima County, Arizona, causes damage and has spawned costly efforts to control bank erosion. Aerial photographs, historical data, and field observations are used to document the history of channel change since 1936. Variability in the nature and degree of channel...
Nutrient reserve dynamics of breeding canvasbacks
Jeb A. Barzen, Jerome R. Serie
1990, The Auk (107) 75-85
We compared nutrients in reproductive and nonreproductive tissues of breeding Canvasbacks (Aythya valisineria) to assess the relative importance of endogenous reserves and exogenous foods. Fat reserves of females increased during rapid follicle growth and varied more widely in size during the early phase of this period. Females began laying with...
Source complexity of the 1987 Whittier Narrows, California, earthquake from the inversion of strong motion records
S. Hartzell, M. Iida
1990, Journal of Geophysical Research Solid Earth (95) 12475-12485
Strong motion records for the Whittier Narrows earthquake are inverted to obtain the history of slip. Both constant rupture velocity models and variable rupture velocity models are considered. The results show a complex rupture process within a relatively small source volume, with at least four separate concentrations of slip. Two...

J. A. Smith, C. T. Chiou, J.A. Kammer, D. E. Kile
1990, Environmental Science & Technology (24) 676-683
This report presents data on the sorption of trichloroethene (TCE) vapor to vadose-zone soil above a contaminated water-table aquifer at Picatinny Arsenal in Morris County, NJ. To assess the impact of moisture on TCE sorption, batch experiments on the sorption of TCE vapor by the field soil were carried out...

Robert I. Tilling, Lyn J. Topinka, Donald A. Swanson
1990, Report
Mount St. Helens, located in southwestern Washington about 50 miles northeast of Portland, Oregon, is one of several lofty volcanic peaks that dominate the Cascade Range of the Pacific Northwest; the range extends from Mount Garibaldi in British Columbia, Canada, to Lassen Peak in northern California. Geologists call Mount St....
Simulation of rockfalls triggered by earthquakes

1990, Rock Mechanics and Rock Engineering (23) 1-20
A computer program to simulate the downslope movement of boulders in rolling or bouncing modes has been developed and applied to actual rockfalls triggered by the Mammoth Lakes, California, earthquake sequence in 1980 and the Central Idaho earthquake in 1983. In order to reproduce a movement mode where bouncing predominated,...

Schlumberger soundings near Medicine Lake, California
A.A.R. Zohdy, R.J. Bisdorf
1990, Geophysics (55) 956-964
The use of direct current resistivity soundings to explore the geothermal potential of the Medicine Lake area in northern California proved to be challenging because of high contact resistances and winding roads. Deep Schlumberger soundings were made by expanding current electrode spacings along the winding roads. Measured apparent resistivities were...
Multi-model stereo restitution
K.S. Dueholm
1990, Photogrammetric Engineering and Remote Sensing (56) 239-242
Methods are described that permit simultaneous orientation of many small-frame photogrammetric models in an analytical plotter. The multi-model software program enables the operator to move freely between the oriented models during interpretation and mapping. Models change automatically when the measuring mark is moved from one frame to another, moving to...

C. Wnuk, J. O. Maberry
1990, Journal of Paleontology (64) 440-450
Enigmatic tubular trace fossils up to eight meters long occur in the Lower Pennsylvanian Middlesboro Member of the Lee Formation.
