Carbon storage and late Holocene chronostratigraphy of a Mississippi River deltaic marsh, St. Bernard Parish, Louisiana
H. W. Markewich, editor(s)
1998, Open-File Report 98-36
Today, the causes, results, and time scale(s) of climate change, past and potential, are the focus of much research, news coverage, and pundit speculation. Many of the US government scientific agencies have some funds earmarked for research into past and (or) future climate change (National Science and Technology Council, 1997)....

Red-shouldered hawk broadcast surveys: Factors affecting detection of responses and population trends
Mary Anne McLeod, David E. Andersen
1998, Journal of Wildlife Management (62) 1385-1397
Forest-nesting raptors are often difficult to detect and monitor because they can be secretive, and their nests can be difficult to locate. Some species, however, respond to broadcasts of taped calls, and these responses may be useful both in monitoring population trends and in locating nests. We conducted broadcast surveys...
Digital representation of a map showing the thickness and character of Quaternary sediments in the glaciated United States east of the Rocky Mountains
D. R. Soller, Patricia H. Packard
1998, Data Series 38
This CD-ROM contains vector-based digital geologic maps of the surficial deposits in parts of 23 states where continental glaciation occurred during the Quaternary. These maps, at 1:1,000,000-scale, include the texture of the surface sediments and the total thickness of Quaternary sediments. Map compilation was based on about 850 sources of...

Statistical analysis and mathematical modeling of a tracer test on the Santa Clara River, Ventura County, California
Katherine S. Paybins, Tracy Nishikawa, John A. Izbicki, Eric G. Reichard
1998, Water-Resources Investigations Report 97-4275
To better understand flow processes, solute-transport processes, and ground-water/surface-water interactions on the Santa Clara River in Ventura County, California, a 24-hour fluorescent-dye tracer study was performed under steady-state flow conditions on a 28-mile reach of the river. The study reach includes perennial (uppermost and lowermost) subreaches and ephemeral subreaches of the...
Summary of suspended-solids concentration data, San Francisco Bay, California, water year 1996
Paul A. Buchanan, David H. Schoellhamer
1998, Open-File Report 98-175
Suspended-solids concentration data were collected in San Francisco Bay during water year 1996 (October 1, 1995?September 30, 1996). Optical backscatterance sensors and water samples were used to monitor suspended solids at three sites in Suisun Bay, three sites in Central San Francisco Bay, and three sites in South San Francisco...
Reservoir quality and diagenetic evolution of Upper Mississippian rocks in the Illinois Basin; influence of a regional hydrothermal fluid-flow event during late diagenesis
Janet K. Pitman, Mitchell E. Henry, Beverly Seyler
1998, Professional Paper 1597
Conventional reservoir quality data for more than 300 wells provided by the Illinois and Indiana State Geological Surveys were analyzed to determine the factors governing porosity and permeability in the Upper Mississippian Bethel Sandstone and Cypress Sandstone, two of the principal producing units in the Illinois Basin. In addition, approximately...
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...

Surface-water quality at fixed sites in the Western Lake Michigan Drainages, Wisconsin and Michigan, and the effects of natural and human factors, 1993-95
K.D. Richards, D. J. Sullivan, J.S. Stewart
1998, Water-Resources Investigations Report 97-4208
Streamwater samples were collected from April 1993 through July 1995 at 11 fixed sites in the Western Lake Michigan Drainages Study Unit of the U.S. Geological Survey's National Water-Quality Assessment Program. Water samples were collected monthly at all Fixed Sites, and an additional two to four samples were collected each...
Magnitude and frequency of floods in Washington
S. S. Sumioka, D. L. Kresch, K.D. Kasnick
1998, Water-Resources Investigations Report 97-4277
Annual maximum instantaneous discharge data for 527 gaging stations with at least 10 years of peak-discharge record on unregulated streams were used to compute the magnitude and frequency of floods on Washington streams. Flood magnitudes having exceedance probabilities of 0.5, 0.1, 0.04, 0.02, and 0.01 were related to physical and...

Hydrologic investigation of the Ophir Creek watershed near Yakutat, Alaska
Edward G. Neal
1998, Open-File Report 98-199
Data on streamflow and ground-water levels were collected in the Ophir Creek watershed in southeast Alaska to obtain information about the relations between streamflow, ground-water levels, and precipitation. In addition, the possible effect of an experimental channel excavation to increase flows in Ophir Creek was evaluated. Stream discharges were monitored...
Factors influencing cattail abundance in the northern Everglades
S. Newman, J. Schuette, James B. Grace, K. Rutchey, T. Fontaine, K.R. Reddy, M. Pietrucha
1998, Aquatic Botany (60) 265-280
Since the early 1900s, the Everglades have been influenced by anthropogenic actions including altered hydrology and increased nutrient loading. In the northern Everglades an apparent effect of these disturbances has been the development and proliferation of dense cattail (Typha spp. ) stands in areas previously dominated by sawgrass (Cladium jamaicense Crantz) and...
The Holocene sea-level highstand in the equatorial Pacific: Analysis of the insular paleosea-level database
E. E. Grossman, C. H. Fletcher, B. M. Richmond
1998, Coral Reefs (17) 309-327
A review of the literature provides 92 estimates of the middle to late Holocene sea-level highstand on Pacific Islands. These data generally support geophysical model calculations that predict a +1 to 3 m relative sea-level highstand on oceanic islands due to the Earth’s rheological response to the melting of the last...

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...
Water-quality trends in the Santa Ana River at MWD Crossing and below Prado Dam, Riverside County, California
Carmen A. Burton, John A. Izbicki, Katherine S. Paybins
1998, Water-Resources Investigations Report 97-4173
The Santa Ana River, located in an extensively urbanized basin, drains about 2,670 square miles near Los Angeles, California. Almost all flow in the river, about 200,000 acre-feet annually, is diverted to ponds where it infiltrates and recharges underlying aquifers. About 2 million people are dependent on these aquifers for...

Jeff V. Phillips, Todd L. Ingersoll
1998, Professional Paper 1584
Physical and hydraulic characteristics are presented for 14 river and canal reaches in Arizona for which 37 roughness coefficients have been determined. The verified roughness coefficients which ranged from 0.017 to 0.067, were computed from discharges, channel geometry, and water-surface profiles measured at each of the sites. The information given...
