Disturbance in a cypress-tupelo wetland: an interaction between thermal loading and hydrology
Michael L. Scott, Rebecca R. Sharitz, Lyndon C. Lee
1985, Wetlands (5) 53-68
The interaction between thermal loading and hydrology was examined in a forested wetland. As a result of flooding, portions of the wetland are periodically exposed to elevated water temperatures, resulting in progressive deterioration of the canopy. We chose three study sites along a gradient of canopy disturbance: most disturbed, intermediate...
A relational approach to vector data structure conversion
Jan W. van Roessel, Eugene A. Fosnight
1985, Conference Paper, Auto-Carto VII: Proceedings of the digital representations of spatial knowledge
The proliferation of geographic information systems and digital data bases is creating a need for efficient methods to convert data from one spatial data structure to another. One approach is to create ad hoc interfaces, with a potential of N(N-1) interfaces for N data structures. Using an intermediate data structure,...

Devonian eustatic fluctuations in Euramerica
J.G. Johnson, Gilbert Klapper, Charles Sandberg
1985, GSA Bulletin (96) 567-587
The Devonian System of Euramerica contains at least 14 transgressive-regressive (T-R) cycles of eustatic origin. These are separated into three groups (or depophases) and from Carboniferous cycles by three prominent regressions. Twelve post-Lochkovian T-R cycles are recognized, and they commonly appear to result from abrupt deepening events followed by prolonged...
16th century European earthquakes described in some contemporary woodcuts
H. Deresiewicz
1985, Earthquake Information Bulletin (USGS) (17) 204-210
In the middle of the 15th century, shortly after Gutenberg’s invention of printing using individual lead type, the first illustrated broadsides (or broadsheets) began appearing in southern Germany. Usually printed on one side of a sheet of paper, they consisted of a woodcut illustration, sometimes colored, either by hand or...
Tsunamis – Scourge of the Pacific
Patricia Lockridge
1985, Earthquake Information Bulletin (USGS) (17) 211-217
Although tsunamis occur most often in the Pacific Ocean, they can be generated by major earthquakes in other areas. The most frequent cause of tsunamis…is crustal movement along a fault: a large mass of rock drops or rises and displaces the column of water above it. This column of water...
Earthquake potential of the Wasatch Fault in Utah
1985, Earthquake Information Bulletin (USGS) (17) 218-225
The majority of Utah’s population lives along the Wasatch fault, an active intraplate normal fault that extends for approximately 230 miles along the western front of the Wasatch Range. Investigations of earthquake recurrence on the Wasatch fault have revealed that segments of the fault have been the source of repeated...
Implications of silicic vent patterns for the presence of large crustal magma chambers
Charles R. Bacon
1985, Journal of Geophysical Research B: Solid Earth (90) 11243-11252
On the basis of the distribution of silicic vents, many volcanic fields can be grouped with (1) igneous systems that may be small and whose vent locations are controlled by regional tectonics, (2) those that include sizable crustal magma bodies which erupt at sites determined by their anomalous local stress...
Gill lamellar dilations (Telangiectasis) related to sampling techniques
R. L. Herman, J. W. Meade
1985, Transactions of the American Fisheries Society (114) 911-913
Among fish killed by concussion (a blow to the head), lake trout Salvelinus namaycush readily developed telangiectasis, lamellar edema, and hemorrhagic thymi; Atlantic salmon Salmo salar and rainbow trout Salmo gairdneri developed thymic hemorrhages but few or no gill lesions. This illustrates a potentially overlooked bias that sampling techniques can...
Field determination of the three-dimensional hydraulic conductivity tensor of anisotropic media: 1. Theory
Paul A. Hsieh, Shlomo P. Neuman
1985, Water Resources Research (21) 1655-1665
A field method is proposed for determining the three-dimensional hydraulic conductivity tensor and specific storage of an anisotropic porous or fractured medium. The method, known as cross-hole testing (to distinguish it from conventional single-hole packer tests), consists of injecting fluid into (or withdrawing fluid from) packed-off intervals in a number...
Assessment of the instantaneous unit hydrograph derived from the theory of topologically random networks
M.R. Karlinger, B.M. Troutman
1985, Water Resources Research (21) 1693-1702
An instantaneous unit hydrograph (iuh) based on the theory of topologically random networks (topological iuh) is evaluated in terms of sets of basin characteristics and hydraulic parameters. Hydrographs were computed using two linear routing methods for each of two drainage basins in the southeastern United States and are the basis...
Origin of the Sudbury Complex by meteoritic impact: Neodymium isotopic evidence
B.E. Faggart Jr., A. R. Basu, Mitsunobu Tatsumoto
1985, Science (230) 436-439
Samarium-neodymium isotopic data on whole rocks and minerals of the Sudbury Complex in Canada gave an igneous crystallization age of 1840 ± 21 × 106 years. The initial epsilon neodymium values for 15 whole rocks are similar to those for average upper continental crust, falling on the crustal trend of neodymium...

Presence and effects of the dog louse Trichodectes canis (Mallophaga, Trichodectidae) on wolves and coyotes from Minnesota and Wisconsin
L. David Mech, Richard P. Thiel, S. H. Fritts, W. E. Berg
1985, American Midland Naturalist (114) 404-405
The dog louse was found on 19 wolves (Canis lupus) and six coyotes (C. latrans) from Minnesota and Wisconsin during the July-February, 1973 through 1983, period. No evidence was found that lice had any serious effect on wolf survival....
Interactions among temporary and permanent meiofauna: Observations on the feeding and behavior of selected taxa
Mary C. Watzin
1985, Biological Bulletin (169) 397-416
Meiofauna diets and behavioral patterns are relatively unknown despite the fact that in any system, predatory relationships and behavioral responses may play an important role in determining community structure. Therefore, observations on food preferences, feeding behavior, and encounter interactions of members of a meiofauna assemblage were made in the laboratory...
On the interpretation of satellite-derived gravity and magnetic data for studies of crustal geology and metallogenesis
David A. Hastings
1985, Conference Paper, Geopotential Research Mission (GRM): Proceedings of a conference
Satellite-derived global gravity and magnetic maps have been shown to be useful in large-scale studies of the Earth's crust, despite the relative infancy of such studies. Numerous authors have made spatial associations of gravity or magnetic anomalies with geological provinces. Gravimetric interpretations are often made in terms of isostasy, regional...

Petroleum industry drilling in industrialized and developing areas
Emil D. Attanasi
1985, Natural Resources Forum (9) 147-153
International drilling statistics show significant differences in target depths as well as the mix between onshore and offshore wells. Unlike the USA, where most of the drilling has been concentrated in depths to 5000 f (shallow depths), the preponderance of wildcat wells drilled in South America and Africa reach much...
Seismic-reflection signature of cretaceous continental breakup on the Wilkes Land margin, Antarctica
Stephen Eittreim, Monty A. Hampton, Jonathan R. Childs
1985, Science (229) 1082-1084
The passive (rifted) continental margin of Wilkes Land, Antarctica, is characterized on seismic reflection records by (i) in the south, a block-faulted sequence of highly stratified continental beds overlain by two distinct unconformities; (ii) a transitional, greatly thinned continental crust overlain by material interpreted to be flood basalt; and (iii)...
Episodic rifting of phanerozoic rocks in the Victoria Land basin, Western Ross Sea, Antarctica
Alan K. Cooper, F.J. Davey
1985, Science (229) 1085-1087
Multichannel seismic-reflection data show that the Victoria Land basin, unlike other sedimentary basins in the Ross Sea, includes a rift-depression 15 to 25 kilometers wide that parallels the Transantarctic Mountains and contains up to 12 kilometers of possible Paleozoic to Holocene age sedimentary rocks. An unconformity separates the previously identified...

1985, Fish Pathology (20) 339-341
A hybridoma cell line that continually secretes antibody against infectious hematopoietic necrosis virus was developed and designated M-IHNV-W1. Antibodies in culture fluids were concentrated and purified by Protein A Sepharose CL-4B affinity chromatography. The immunoglobulin was isotyped as IgG 2b with a kappa light chain. The IgG was specific for...
