A geographic information systems technique for monitoring contaminants in Galveston Bay, Texas
Marcia McNiff, P.F. Roscigno, W. Ji
1992, Conference Paper, Needs and Solutions for Pollution Monitoring, Control, and Abatement: Proceedings of the First Thematic Conference on Remote Sensing for Marine and Coastal Environments
A geographic information system (GIS) was used to compile a series of databases containing details concerning metal contamination and pollution sources to study their impacts on the Galveston Bay (TX) ecosystem. Using these databases, a series of maps with various overlays was created with ARC/INFO software. These maps allowed patterns...
Remote sensing studies of the geomorphology of Surtsey, 1987-1991
James B. Garvin, R. S. Williams Jr.
1992, Report
The volcanic island of Surtsey, formed by explosive submarine and effusive subaerial eruptions between November 1963 and June 1967, consists of a complex combination of primary and redeposited tephra and alkaline olivine basalt lava flows in a 2.5 km2 area (Thorarinsson, 1967; Thorarinsson et al., 1964; Fridriksson, 1975). During the...
Interoceanic variation in the rare earth, major, and trace element depositional chemistry of chert: Perspectives gained from the DSDP and ODP record
R.W. Murray, Marilyn R. Buchholtz ten Brink, David C. Gerlach, G. Price Russ, David L. Jones
1992, Geochimica et Cosmochimica Acta (56) 1897-1913
Rare earth element (REE), major, and trace element abundances and relative fractionations in forty nodular cherts sampled by the Deep Sea Drilling Project (DSDP) and Ocean Drilling Program (ODP) indicate that the REE composition of chert records the interplay between terrigenous sources and scavenging from the local seawater. Major and...
Deposition of aerially applied BT in an oak forest and its prediction with the FSCBG model
Dean E. Anderson, David R. Miller, Yansen Wang, William G. Yendol, Karl Mierzejewski, Michael L. McManus
1992, Journal of Applied Meteorology (31) 1457-1466
Data are provided from 17 single-swath aerial spray trials that were conducted over a fully leafed, 16-m tall, mixed oak forest. The distribution of cross-swath spray deposits was sampled at the top of the canopy and below the canopy. Micrometeorological conditions were measured above and within the canopy during the...

Zhijia Zhan, Fuxin Yao, M. Johnston, R. Mueller, Jintian Gao
1992, Acta Seismologica Sinica (5) 807-813
Using observational data of geomagnetic total intensity from 13 stations in the Beijing-Tianjin region, 3 stations in the western Yunnan region of China, and 6 stations in California of U. S. A., the daily variations and their spectra of geomagnetic total intensity were analyzed and compared. The results show that...
Enhanced visualization for the interpretation of Magellan radar data: Supplement to the Magellan special issue
Randolph L. Kirk, Laurence A. Soderblom, Ella M. Lee
1992, Journal of Geophysical Research E: Planets (97) 16371-16380
The differences of radar data from more familiar photographic images, coupled with the unique geologic characteristics of Venus's surface, can make interpretation of the standard Magellan data products difficult for both planetary scientists and nonspecialists. We describe a set of digital processing techniques for transforming individual remote‐sensing datasets in order...
Pliocene paleoclimatic interpretation of DSDP Site 580 (NW Pacific) using diatoms
John A. Barron
1992, Marine Micropaleontology (20) 23-44
High-resolution quantitative diatom data are tabulated for the early part of the late Pliocene (3.25 to 2.08 Ma) at DSDP Site 580 in the northwestern Pacific. Sample spacing averages 11 k.y. between 3.1 and 2.8 Ma, but increases to 14 to 19 k.y. prior to 3.1 Ma and after 2.8...
Wildlife species richness in shelterbelts: test of a habitat model
Richard L. Schroeder, Ted T. Cable, Sandra L. Haire
1992, Wildlife Society Bulletin (20) 264-273
Shelterbelts are human-made habitats consisting of rows of shrubs and trees planted either in fields or on the windward side of farmstead dwellings. Shelterbelts provide wooded habitat for a large variety of birds and other wildlife. A model to predict wildlife species richness in shelterbelts (Schroeder 1986) was published as...
The geology and distribution of impact craters on Venus: What are they telling us?
G. G. Schaber, R.G. Strom, H. J. Moore, Laurence A. Soderblom, Randolph L. Kirk, D.J. Chadwick, D.D. Dawson, Lisa R. Gaddis, J. M. Boyce, Joel F. Russell
1992, Journal of Geophysical Research E: Planets (97) 13257-13301
Magellan has revealed an ensemble of impact craters on Venus that is unique in many important ways. We have compiled a data base describing the 842 craters on 89% of Venus' surface mapped through orbit 2578. (The craters range in diameter from 1.5 to 280 km.) We have studied the...
Alternate reproductive strategies in the California gull
Bruce H. Pugesek, P. Wood
1992, Evolutionary Ecology (6) 279-295
We analysed 6 years of reproduction data for 176 California gulls (Larus californicus) surviving from 1980 to 1988. Using a statistical model adapted from Rao's (1958) and Tucker's (1966) generalized growth curve analysis, we reconstructed the reproductive patterns of gulls aged from 0 to 26 years. Individuals were...
Seismic constraints on the nature of lower crustal reflectors beneath the extending Southern Transition Zone of the Colorado Plateau, Arizona
Thomas E. Parsons, John M. Howie, George A. Thompson
1992, Journal of Geophysical Research B: Solid Earth (97) 12391-12407
We determine the reflection polarity and exploit variations in P and S wave reflectivity and P wave amplitude versus offset (AVO) to constrain the origin of lower crustal reflectivity observed on new three-component seismic data recorded across the structural transition of the Colorado Plateau. The near vertical incidence reflection data...
Large-scale natural gradient tracer test in sand and gravel, Cape Cod, Massachusetts: 3. Hydraulic conductivity variability and calculated macrodispersivities
Kathryn M. Hess, Steven H. Wolf, Michael A. Celia
1992, Water Resources Research (28) 2011-2027
Hydraulic conductivity (K) variability in a sand and gravel aquifer on Cape Cod, Massachusetts, was measured and subsequently used in stochastic transport theories to estimate macrodispersivities. Nearly 1500 K measurements were obtained by borehole flowmeter tests and permeameter analyses of cores. The geometric mean for the flowmeter tests (0.11 cm/s)...
Precipitation estimation in mountainous terrain using multivariate geostatistics. Part I: structural analysis
Joseph A. Hevesi, Jonathan D. Istok, Alan L. Flint
1992, Journal of Applied Meteorology (31) 661-676
Values of average annual precipitation (AAP) are desired for hydrologic studies within a watershed containing Yucca Mountain, Nevada, a potential site for a high-level nuclear-waste repository. Reliable values of AAP are not yet available for most areas within this watershed because of a sparsity of precipitation measurements and the need...
Precipitation estimation in mountainous terrain using multivariate geostatistics. Part II: isohyetal maps
Joseph A. Hevesi, Alan L. Flint, Jonathan D. Istok
1992, Journal of Applied Meteorology (31) 677-688
Values of average annual precipitation (AAP) may be important for hydrologic characterization of a potential high-level nuclear-waste repository site at Yucca Mountain, Nevada. Reliable measurements of AAP are sparse in the vicinity of Yucca Mountain, and estimates of AAP were needed for an isohyetal mapping over a 2600-square-mile watershed containing...
Annual survival rates of adult and immature eastern population tundra swans
James D. Nichols, J. Bart, Roland J. Limpert, William J.L. Sladen, James E. Hines
1992, Journal of Wildlife Management (56) 485-494
Tundra swans (Cygnus columbianus) of the eastern population were neckbanded in Maryland, North Carolina, and Alaska from 1966 through 1990. These swans were resighted and recaptured during autumn, winter, and spring, 1966-1990. Although the original motivation for this study involved swan movements, we wanted to use the resulting data to...
Evaluation of aerial transects for counting winter mallards
Kenneth J. Reinecke, Michael W. Brown, James R. Nassar
1992, Journal of Wildlife Management (56) 515-525
Winter waterfowl surveys rarely use sampling methods, and little is known about the precision and biases of their population estimates. Consequently, we developed aerial transect surveys (n=5) in 4 strata comprising 16 substrata in the lower Mississippi Alluvial Valley during winters 1987-88 through 1989-90 to estimate mallard (Anas platyrhynchos) population...
