Hydrogen concentrations as an indicator of the predominant terminal electron-accepting reactions in aquatic sediments
Derek R. Lovley, S. Goodwin
1988, Geochimica et Cosmochimica Acta (52) 2993-3003
Factors controlling the concentration of dissolved hydrogen gas in anaerobic sedimentary environments were investigated. Results, presented here or previously, demonstrated that, in sediments, only microorganisms catalyze the oxidation of H2 coupled to the reduction of nitrate, Mn(IV), Fe(III), sulfate, or carbon dioxide. Theoretical considerations suggested that, at steady-state conditions, H2...
Rainfall intensity-duration equations
David C. Froehlich
1988, Conference Paper
A method for rapidly developing a rainfall intensity-duration equation for durations less than one hour and recurrence intervals between 2 and 100 years for any location in the conterminous United States is presented. Optimal parameters of a general rainfall-intensity duration equation are determined using precipitation depths for durations of 5,...

Populations, productivity, and feeding habits of seabirds on St. Lawrence Island, Alaska: Final report
John F. Piatt, Scott A. Hatch, Bay D. Roberts, Wayne W. Lidster, John L. Wells, J. Christopher Haney
1988, Report
A field camp was established at Kongkok Bay near the southwest cape of St. Lawrence Island and occupied continuously from 24 May to 2 September 1987. Permanent study plots were selected for both cliff and crevice-nesting species, and regular observations were made throughout the breeding season to document attendance patterns,...
Use of the truncated shifted Pareto distribution in assessing size distribution of oil and gas fields
J.C. Houghton
1988, Mathematical Geology (20) 907-937
The truncated shifted Pareto (TSP) distribution, a variant of the two-parameter Pareto distribution, in which one parameter is added to shift the distribution right and left and the right-hand side is truncated, is used to model size distributions of oil and gas fields for resource assessment. Assumptions about limits to...
Dichlorobenzene in ground water: Evidence for long-term persistence
Larry B. Barber
1988, Ground Water (26) 696-732
Hydrologic and geochemical evidence were used to establish the long-term persistence of dichlorobenzene in ground water that has been contaminated from 50 years of rapid-infiltration sewage disposal. An extensive plume of dichlorobenzene extends more than 3,500 meters downgradient from the disposal beds, with concentrations of the combined isomers ranging from...
Isotopic studies of epigenetic features in metalliferous sediment, Atlantis II Deep, Red Sea
Robert A. Zierenberg, Wayne C. Shanks III
1988, Canadian Mineralogist (26 pt 3) 737-753
The unique depositional environment of the Atlantis II Deep brine pool in the Red Sea produces a stratiform metalliferous deposit of greater areal extent than deposits formed by buoyant-plume systems typical of the midocean ridges because of much more efficient metal entrapment. Isotopic analyses of strontium, sulfur, carbon, and oxygen...
Persistent toxic substances and the health of fish communities in the Great Lakes

1988, Book chapter, Toxic contaminants and ecosystem health: a Great Lakes focus
The role, if any, of toxic substances in bringing about changes in the productivity and status of fishery resources, is not well understood. At the 'Workshops on Persistent Toxic Substances and the Health of the Aquatic Community,' the Fish Biota Discussion Subgroup considered the issue of toxic substances by...

Areal variation in recharge to and discharge from the Floridan aquifer system in Florida
Walter R. Aucott
1988, Water-Resources Investigations Report 88-4057
This report is a revision and update of existing recharge maps of the Floridan aquifer system to include quantitative information derived from Regional Aquifer Systems Analysis models as well as other recent information and also includes information on discharge from the system. The report represents predevelopment conditions with inset map...
Effects of the 1982-83 El Niño – Southern Oscillation on Pacific Ocean bird populations

Seabird reproductive success, population size, and movements in the Pacific region responded dramatically to the 1982-83 El Niño – Southern Oscillation (ENSO). At sites within the North and South Pacific Gyres, the onset of seabird responses tracked oceanographic changes related to ENSO; to the north of the gyres, responses were...
Sorption characteristics of organic compounds on hexadecyltrimethylammonium-smectite
Stephen A. Boyd, Max M. Mortland, Cary T. Chiou
1988, Soil Science Society of America Journal (52) 652-657
When hexadedyltrimethylammonium (HDTMA) ion is exchanged for metal cations like calcium in smectite, the sorptive properties of the clay are greatly modified. The resultant HDTMA-smectite complex behaves as a dual sorbent, in the sorption of organic compounds, in which the mineral fraction functions as a solid adsorbent and the organic...
Volcanoes can generate devastating waves
1988, Earthquakes & Volcanoes (USGS)
Explosions. Noxious gases. Lava fountains and flows. Avalanches of superheated pyroclastics. Although volcanic eruptions can cause all these frightening phenomena, it is often the power of the sea that causes many volcano-related deaths. this destruction comes from tsunamis (huge volcano-generated waves) Roughly one-fourth of the deaths occurring during volcanic eruptions...
Genetic interpretations of elemental and chemical differences in a soil chronosequence, California
J.W. Harden
1988, Geoderma (43) 179-193
Soils developed on fluvial terraces in central California have similar parent materials, climatic settings, vegetation cover and slopes but range in age from 40,000 to 3,000,000 years. The soils have chemical compositions that change systematically with increasing age. Such chemical differentiation is most likely the result of long-term weathering and...

1988, Water-Resources Investigations Report 89-4008
Aqueous chemical and radioactive wastes discharged since 1952 to unlined ponds and wells at the INEL (Idaho National Engineering Laboratory) have affected water quality in perched groundwater zones and in the Snake River Plain Aquifer. Routine waste water disposal was changed from deep injection wells to ponds at the ICPP...

Effectiveness of an urban runoff detention pond - Wetlands system
E.H. Martin
1988, Journal of Environmental Engineering (114) 810-827
The effectiveness of an urban detention system, composed of a detention pond and wetlands in series, in reducing constituent loads carried in runoff was determined. The detention pond was effective in reducing loads of suspended solids and suspended metals. Suspendedphase efficiencies for solids, lead, and zinc ranged between 42 and...
Radiolarian biostratigraphy of siliceous Eocene deposits in central California
J. Blueford
1988, Micropaleontology (34) 236-258
Abundant Eocene siliceous deposits in California are located in the San Joaquin and Sacramento valleys. The white shales to buff mudstones are characterized by radiolarians, diatoms, and silicoflagellates. Taxonomic descriptions and abundance data of key radiolarian species in existing monographs have limited biostratigraphic and paleoenvironmental interpretation. The California fauna is...
Effects of sulfur dioxide emissions on stream chemistry in the western United States
K. Campbell, J.T. Turk
1988, Water Resources Research (24) 871-878
A 20-year record of water chemistry for seven headwater streams in the Rocky Mountain region of the western United States is compared to estimates of local and regional sulfur dioxide emissions for the same period. Emissions from smelters in the region comprise a significant part of sulfur dioxide emissions for...
Coastal geomorphology of arctic Alaska
Peter W. Barnes, Stuart E. Rawlinson, Erk Reimnitz
1988, Technical Council on Cold Regions Engineering Monograph 3-30
The treeless, tundra-plain of northern Alaska merges with the Arctic Ocean along a coastal area characterized by low tundra bluffs, and sparse coastal and delta dunes. Coastal engineering projects that aggrade or degrade permafrost will alter the geomorphology and rates of coastal processes by changing coastal stability. Similarly, projects that...

Contrasting serpentinization processes in the eastern Central Alps
D.J.M. Burkhard, J. R. O’Neil
1988, Contributions to Mineralogy and Petrology (99) 498-506
Stable isotope compositions have been determined for serpentinites from between Davos (Arosa-Platta nappe, Switzerland) and the Valmalenco (Italy). ??D and ??18O values (-120 to -60 and 6-10???, respectively) in the Arosa-Platta nappe indicate that serpentinization took place on the continent at relatively low temperatures in the presence of limited amounts...
