Variations in rupture process with recurrence interval in a repeated small earthquake
J.E. Vidale, W.L. Ellsworth, A. Cole, Chris Marone
1994, Nature (368) 624-626
In theory and in laboratory experiments, friction on sliding surfaces such as rock, glass and metal increases with time since the previous episode of slip. This time dependence is a central pillar of the friction laws widely used to model earthquake phenomena. On natural faults, other properties, such as rupture...
Chaotic deposition by a giant wave, Molokai, Hawaii
J.G. Moore, W.B. Bryan, K.R. Ludwig
1994, Geological Society of America Bulletin (106) 962-967
A coral-basalt breccia-conglomerate is exposed >60m above present sea level and nearly 2km inland from the present shoreline on the southwest side of East Molokai Volcano. This deposits was apparently laid down by a giant wave that broke over an outer reef, similar to the present fringing reef, and advanced...

Artifacts resembling budding bacteria produced in placer-gold amalgams by nitric acid leaching
J.R. Watterson
1994, Geology (22) 1131-1134
Microscopic filiform morphologies in gold which are indistinguishable from forms originally interpreted as bacterial in origin were produced in the laboratory by treating amalgams made from natural and artificial gold with hot nitric acid. Textures ranging from cobblestone to deeply crenulated to nodular...

Water-resources data for the 1993 water year for West Virginia consist of records of stage, discharge, and water quality of streams; contents of reservoirs; and water levels of observations wells. This report contains discharge records for 78 streamflow-gaging stations; stage only records for 11 gaging stations; annual maximum discharge at...
Model for dolomite formation in northwest Florida
C.R. Cooper, J.A. Tindall
1994, Journal of Hydrology (157) 367-391
Petrographic methods are used to examine the nature of the Floridan post-Oligocene unconformity and diagenetic responses in the associated carbonate units. The study addresses the depositional environment and the character of sediments associated with the unconformity, types and timing of diagenetic changes, and mode of dolomitization for the Suwannee Limestone...
Reductive dehalogenation of hexachloroethane, carbon tetrachloride, and bromoform by anthrahydroquinone disulfonate and humic acid
G.P. Curtis, M. Reinhard
1994, Environmental Science & Technology (28) 2393-2401
The reductive dehalogenation of hexachloroethane (C2Cl6), carbon tetrachloride (CCl4), and bromoform (CHBr3) was examined at 50??C in aqueous solutions containing either (1) 500 ??M of 2,6-anthrahydroquinone disulfonate (AHQDS), (2) 250 ??M Fe2+, or (3) 250 ??M HS-. The pH ranged from 4.5 to 11.5 for AHQDS solutions and was 7.2...

Climate, interseasonal storage of soil water, and the annual water balance
P. C. D. Milly
1994, Advances in Water Resources (17) 19-24
The effects of annual totals and seasonal variations of precipitation and potential evaporation on the annual water balance are explored. It is assumed that the only other factor of significance to annual water balance is a simple process of water storage, and that the relevant storage capacity is the plant-available...
Plasma chloride and gill epithelial response of channel catfish to infection with Ichthyophthirius multifillis
M. S. Ewing, M.C. Black, V. S. Blazer, K. M. Kocan
1994, Journal of Aquatic Animal Health (6) 187-196
Because infection with Ichthyophthirius multifiliis has been reported to result in osmotic stress, genesis of the plasma chloride and chloride cell response of channel catfish Ictalurus punctatus to the infection was studied from day 0 to day 7 postexposure (PE). Parasite population densities ranged from 0.08 to 0.22 trophonts per...
Recent applications of acoustic Doppler current profilers
K. A. Oberg, David S. Mueller
1994, Conference Paper, Proceedings of the Symposium on Fundamentals and Advancements in Hydraulic Measurements and Experimentation
A Broadband acoustic Doppler current profiler (BB-ADCP) is a new instrument being used by the U.S. Geological Survey (USGS) to measure stream discharge and velocities, and bathymetry. During the 1993 Mississippi River flood, more than 160 high-flow BB-ADCP measurements were made by the USGS at eight locations between Quincy and...
Hydrous carbonates on Mars?: Evidence from Mariner 6/7 infrared spectrometer and ground‐based telescopic spectra
W. M. Calvin, T. V. V. King, Roger N. Clark
1994, Journal of Geophysical Research (99) 14659-14675
Absorption features at 2.28 and 5.4 μm identified in Mariner 6/7 infrared spectrometer and terrestrial telescopic spectra are consistent with the spectra of hydrous magnesium carbonates such as hydromagnesite and artinite. Spectral characteristics of these hydrous carbonates are different from those of the anhydrous carbonates, as the former do not...
Uranium(VI) adsorption to ferrihydrite: Application of a surface complexation model
T.D. Waite, J.A. Davis, T.E. Payne, G.A. Waychunas, N. Xu
1994, Geochimica et Cosmochimica Acta (58) 5465-5478
A study of U(VI) adsorption by ferrihydrite was conducted over a wide range of U(VI) concentrations, pH, and at two partial pressures of carbon dioxide. A two-site (strong- and weak-affinity sites, FesOH and FewOH, respectively) surface complexation model was able to describe the experimental data well over a wide range...
Geochemistry of the 1989-1990 eruption of redoubt volcano: Part II. Evidence from mineral and glass chemistry
S.E. Swanson, C.J. Nye, T. P. Miller, V.F. Avery
1994, Journal of Volcanology and Geothermal Research (62) 453-468
Early stages (December 1989) of the 1989-1990 eruption of Redoubt Volcano produced two distinct lavas. Both lavas are high-silica andesites with a narrow range of bulk composition (58-64 wt.%) and similar mineralogies (phenocrysts of plagioclase, hornblende, augite, hypersthene and FeTi oxides in a groundmass of the same phases plus glass)....
Disruption of Drift glacier and origin of floods during the 1989-1990 eruptions of Redoubt Volcano, Alaska
D.C. Trabant, R. B. Waitt, J. J. Major
1994, Journal of Volcanology and Geothermal Research (62) 369-385
Melting of snow and glacier ice during the 1989–1990 eruption of Redoubt Volcano caused winter flooding of the Drift River. Drift glacier was beheaded when 113 to 121 × 106 m3 of perennial snow and ice were mechanically entrained in hot-rock avalanches and pyroclastic flows initiated by the four largest eruptions between...

R. C. Cipriano, L.A. Ford, T.E. Jones
1994, Journal of Wildlife Diseases (30) 577-580
Fish were sampled at the Ed Weed State Fish Hatchery (South Hero, Vermont, USA) in September 1992. Aeromonas salmonicida was common, with concentrations as high as 105 to 107 colony-forming units per gram of mucus, and readily recovered from most mucus samples obtained from furunculosis-sensitive populations of...
