G. L. Brewster-Wingard, S. E. Ishman, N.J. Waibel, Debra A. Willard, Lucy E. Edwards, C. W. Holmes
1998, Open-File Report 98-122
Sediments from Pass Key core 37, in eastern Florida Bay (N 25.1478, W 80.5745) record a history of rapid sedimentation during this century. The lowest portion of the core contains benthic fauna indicative of relatively low salinities and sparse seagrass coverage. This period is followed by an increase in salinity...

G. Lynn Wingard, S. E. Ishman, C. W. Holmes
1998, Journal of Coastal Research (26) 162-172
Analyses of four cores located in the northern transitional, eastern, and central portions of Florida Bay reveal historical patterns of change in salinity and seagrass distribution. Salinity and the distribution of seagrass beds are two critical issues for the restoration of Florida Bay. The distribution of benthic fauna in Bob...
Population demographics of two local South Carolina mourning dove populations
Donald P. McGowan Jr., David L. Otis
1998, Journal of Wildlife Management (62) 1443-1451
The mourning dove (Zenaida macroura) call-count index had a significant (P < 0.01) negative trend in South Carolina and the Eastern Management Unit (EMU) during 1988-97. We initiated a banding study in 2 areas in the Coastal Plain of South Carolina to estimate population demographic parameters of doves to generate...

Hydrogeology and simulation of the effects of reclaimed-water application in west Orange and southeast Lake counties, Florida
Andrew M. O’Reilly
1998, Water-Resources Investigations Report 97-4199
Wastewater reclamation and reuse has become increasingly popular as water agencies search for alternative water-supply and wastewater-disposal options. Several governmental agencies in central Florida currently use the land-based application of reclaimed water (wastewater that has been treated beyond secondary treatment) as a management alternative to surface-water disposal of wastewater. Water...
Vulnerability of island tropical montane cloud forests to climate change, with special reference to East Maui, Hawaii
Lloyd L. Loope, Thomas W. Giambelluca
1998, Climatic Change (39) 503-517
Island tropical montane cloud forests may be among the most sensitive of the world's ecosystems to global climate change. Measurements in and above a montane cloud forest on East Maui, Hawaii, document steep microclimatic gradients. Relatively small climate-driven shifts in patterns of atmospheric circulation are likely to trigger major local...

Nancy E. King, Wayne R. Thatcher
1998, Journal of Geophysical Research: Solid Earth (103) 18069-18086
Geodetic arrays observed by the U.S. Coast and Geodetic Survey span the Imperial fault in southern California. For the 1940 M 7.1 Imperial Valley earthquake, a 1934–1941 triangulation network has sufficient resolution to allow inversion for the coseismic slip distribution on fault segments 5 to 25 km long extending from the surface...

J.C. Savage, R.W. Simpson, M.H. Murray
1998, Journal of Geophysical Research: Solid Earth (103) 18039-18051
Maps of the strain accumulation rate in the San Francisco Bay area have been constructed from trilateration observations extending from about 1972 until the Loma Prieta earthquake in late 1989. The observations were corrected to remove offsets imposed by shallow fault creep and by four M ∼6 earthquakes that occurred...

Kathleen A. McCarthy, Michael R. Lilly, Joan F. Braddock, Larry D. Hinzman
1998, Open-File Report 98-198
Natural attenuation processes include biological degradation, by which microorganisms break down contaminants into simpler product compounds; adsorption of contaminants to soil particles, which decreases the mass of contaminants dissolved in ground water; and dispersion, which decreases dissolved contaminant concentrations through dilution. The primary objectives of this study are to (1)...

West margin of North America - A synthesis of recent seismic transects
G. S. Fuis
1998, Tectonophysics (288) 265-292
A comparison of the deep structure along nine recent transects of the west margin of North America shows many important similarities and differences. Common tectonic elements identified in the deep structure along these transects include actively subducting oceanic crust, accreted oceanic/arc (or oceanic-like) lithosphere of Mesozoic through Cenozoic ages. Cenozoic...
