Petrologic constraints on rift-zone processes - Results from episode 1 of the Puu Oo eruption of Kilauea volcano, Hawaii
M.O. Garcia, R.A. Ho, J.M. Rhodes, E.W. Wolfe
1989, Bulletin of Volcanology (52) 81-96
The Puu Oo eruption in the middle of Kilauea volcano's east rift zone provides an excellent opportunity to utilize petrologic constraints to interpret rift-zone processes. Emplacement of a dike began 24 hours before the start of the eruption on 3 January 1983. Seismic and geodetic evidence indicates that the dike...
Kinky vitrinite reflectance well profiles: Evidence of paleopore pressure in low-permeability, gas-bearing sequences in Rocky Mountain foreland basins
B. E. Law, V. F. Nuccio, C.E. Barker
1989, American Association of Petroleum Geologists Bulletin (73) 999-1010
Vitrinite reflectance (Rm) profiles of wells drilled in abnormally pressured, low-permeability gas-bearing sequences in Rocky Mountain foreland basins are commonly nonlinear with two or more nonparallel segments. These kinky profiles are most likely due to perturbations of the thermal gradient caused by contrasting heat transfer processes associated with the development...

G. R. Stehly, W. L. Hayton
1989, Xenobiotica (19) 75-81
Interspecies variability in the metabolism of pentachlorophenol (PCP) was investigated by exposing rainbow trout, fathead minnows, sheepshead minnow, firemouth, and goldfish to water-borne super(14)C-PCP for 64 h. The amounts of metabolites in bile and exposure water were species-dependent; all of the metabolites excreted into the water...
Iterative techniques for characterizing marine bird habitats with time-series of satellite images
J. Christopher Haney
1989, Colonial Waterbirds (12) 78-89
Demonstrating long-term habitat use of marine habitats by seabirds is often complicated by short-term changes in habitat locations, persistence, and age. This paper describes iterative techniques for characterizing non-static habitats, such as meso-scale (10-100 km) ocean eddies and fronts, using time-series of satellite images that define sea surface conditions. Seabird...

Early concepts of the role of microorganisms in hydrogeology
William Back
1989, Ground Water (27) 618-622
Hydrogeologists and geochemists have made great progress in the past few decades in understanding the water/rock interaction that are major controls on the chemical character of ground water. We also recognize that, for many reactions, we do not understand the specific mechanisms generating these reactions, such as those involved in...
Sidescan sonar examination of deteriorated revetments and bulkheads along Chicago's lake front
Michael J. Chrzastowski
1989, Conference Paper, Coastal Zone: Proceedings of the Symposium on Coastal and Ocean Management
Lakefill for parks along Chicago's lake front is primarily defended with aged, deteriorated revetments. Survey by 100- and 500-kHz sidescan sonar documents that structural failure of the revetments is not related to lake-bottom undermining. The size and weight of the rock fill in the cribs is identified as a critical...
