Mitigating oil and gas impacts in coastal wetlands
Donald R. Cahoon, Joseph C. Holmes Jr.
1989, Conference Paper, Coastal Zone: Proceedings of the Symposium on Coastal and Ocean Management
This abstract refers to technical recommendations for avoiding, minimizing, and restoring (i.e., mitigating) drilling site access impacts related to oil and gas activities in coastal wetlands through regulatory review, drawing mostly from the Louisiana experience. The two standard methods used to access wetland drilling locations are canals and roads, both...
A record of Appalachian denudation in postrift Mesozoic and Cenozoic sedimentary deposits of the U.S. Middle Atlantic continental margin
C. W. Poag, W. D. Sevon
1989, Geomorphology (2) 119-157
The complex interplay between source-terrain uplift, basin subsidence, paleoclimatic shifts, and sea-level change, left an extensive sedimentary record in the contiguous offshore basins of the U.S. middle Atlantic margin (Salisbury Embayment, Baltimore Canyon Trough, and Hatteras Basin). Isopach maps of 23 postrift...
Arsenic in ground-water under oxidizing conditions, south-west United States
F. N. Robertson
1989, Environmental Geochemistry and Health (11) 171-185
Concentrations of dissolved arsenic in ground-water in alluvial basins of Arizona commonly exceed 50 μg L−1 and reach values as large as 1,300 μg L−1. Arsenic speciation analyses show that arsenic occurs in the fully oxidized state of plus 5 (As+5), most likely in the form of...
Description of an estuarine methylotrophic methanogen, which grows on dimethyl sulfite
Ronald S. Oremland, Ronald P. Kiene, Indra Mathrani, Michael J. Whiticar, David R. Boone
1989, Applied and Environmental Microbiology (55) 994-1002
Characteristics of an obligately methylotrophic coccoid methanogen (strain GS-16) previously isolated from estuarine sediment are described. Growth was demonstrated on dimethyl sulfide (DMS) or trimethylamine (TMA), but not on methane thiol, methane thiol plus hydrogen, dimethyl disulfide, or methionine. DMS-grown cells were able to metabolize DMS...
Potentiometric surface of the Peedee aquifer in the central coastal plain of North Carolina, December 1986
Allen R. Brockman, William L. Lyke, M. D. Winner Jr.
1989, Water-Resources Investigations Report 87-4236
Water level measurements were made in 37 wells open to the Peedee aquifer at the end of 1986 to determine the configuration of its potentiometric surface over an area of about 4,100 square miles in the central Coastal Plain of North Carolina. The potentiometric surface of the Peedee slopes southeastward...
Climate variability in an estuary: Effects of riverflow on San Francisco Bay
David H. Peterson, Daniel R. Cayan, John F. Festa, Frederic H. Nichols, Roy A. Walters, James V. Slack, Stephen E. Hager, Laurence E. Schemel
David H. Peterson, editor(s)
1989, Book chapter, Aspects of climate variability in the Pacific and the Western Americas
A simple conceptual model of estuarine variability in the context of climate forcing has been formulated using up to 65 years of estimated mean-monthly delta flow, the cumulative freshwater flow to San Francisco Bay from the Sacramento-San Joaquin River, and salinity observations near the mouth, head, mid-estuary, and coastal...
Winter survival of female American black ducks on the Atlantic coast
Michael J. Conroy, Gary R. Costanzo, Daniel B. Stotts
1989, Journal of Wildlife Management (53) 99-109
We used radio telemetry to monitor the winter survival and cause-specific mortality of 227 female American black ducks (Anas rubripes) captured in New Jersey and Virginia, 1983-85. Mean survival rate for 19 December-15 February was 0.65. Survival from hunting and nonhunting risk was 0.84 and 0.78, respectively. Causes of nonhunting...
Paleomagnetic study of the Eastern Klamath terrane, California, and implications for the tectonic history of the Klamath Mountains Province
Edward A. Mankinen, William P. Irwin, C. Sherman Gromme
1989, Journal of Geophysical Research B: Solid Earth (94) 10444-10472
Paleomagnetic study of Permian through Jurassic volcanic and sedimentary strata of the Eastern Klamath terrane has shown the remanent magnetization of many of these rocks to be prefolding and most likely primary. Similarities in magnetic declinations recorded by coeval strata over a broad area are consistent with the hypothesis that...
Remote characterization of marine bird habitats with satellite imagery
J. Christopher Haney
1989, Colonial Waterbirds (12) 67-77
Remote sensing techniques such as radar altimetry, synthetic aperture radar, coastal zone color scanning, and infrared radiometry provide effective, instantaneous, and relatively inexpensive means for characterizing critical habitats of marine birds. In order to make optimal use of satellite-derived data, the rationale for marine habitat classification is presented, and advantages...
Publications of the U.S. Geological Survey, 1988
Water Resources Division, U.S. Geological Survey
1989, Report
This catalog is a list of (1) books and maps that were published during 1988, and (2) articles by Geological Survey personnel in non-Geological Survey journals and books that came to our attention in 1988; it supplements the permanent catalogs "Publications of the Geological Survey, 1879-1961", "Publications of the Geological...
Artificial recharge to the Floridan aquifer system, Orlando Area, Central Florida
E. R. German, L. A. Bradner
1989, Conference Paper
Approximately 400 drainage wells exist in Orange County, central Florida. The rate of recharge through drainage wells is limited by the rate of surface flow to the wells; the hydraulic properties of weirs, overflow pipes, and well casings; or the water level above the top of the casing. The rate...
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...
Hydrologic effects on water level changes associated with episodic fault creep near Parkfield, California
E.A. Roeloffs, S.S. Burford, F. S. Riley, A.W. Records
1989, Journal of Geophysical Research Solid Earth (94) 12387-12402
As part of the Parkfield, California, earthquake prediction experiment, water level is monitored in a well 460 m from the main trace of the San Andreas fault on Middle Mountain, in the preparation zone of the anticipated Parkfield earthquake. The well configuration allows water level to be monitored in two...
Effect of climate change on watershed runoff
D.M. Wolock, M. A. Ayers, L.E. Hay, G. J. McCabe Jr.
1989, Conference Paper
This paper examines forecasts of changes in watershed runoff in the Delaware River basin that result from a range of predicted effects of increased atmospheric carbon dioxide (CO2) on future precipitation, temperature, and stomatal resistance of plants. A deterministic hydrologic model, TOPMODEL, was driven with stochastic inputs of temperature and...
Eustatic and tectonic controls on deposition of hybrid siliciclastic/carbonate basinal cycles: Discussion with examples
James F. Dolan
1989, American Association of Petroleum Geologists Bulletin (73) 1233-1246
Changes in sea level represent one of the dominant controls on basinal sedimentation adjacent to mixed carbonate siliciclastic sediment-source areas. Sedimentary responses to sea level change of the siliciclastic and carbonate components of these hybrid systems commonly result in deposition of alternating siliciclastic and shelf-derived carbonate basinal deposits. Such deposition...
Enrichment of trace elements in garnet amphibolites from a paleo-subduction zone: Catalina Schist, southern California
Sorena S. Sorensen, J. N. Grossman
1989, Geochimica et Cosmochimica Acta (53) 3155-3177
The abundance, P-T stability, solubility, and element-partitioning behavior of minerals such as rutile, garnet, sphene, apatite, zircon, zoisite, and allanite are critical variables in models for mass transfer from the slab to the mantle wedge in deep regions of subduction zones. The influence of these minerals on the composition of subduction-related magmas...
