Variability in geyser eruptive timing and its causes: Yellowstone National Park
S. Rojstaczer, D. L. Galloway, S. E. Ingebritsen, D. M. Rubin
2003, Geophysical Research Letters (30) 1953-1956
Field data from Upper Geyser Basin, Yellowstone, indicate that geyser frequency is less sensitive to elastic deformation than might be surmised from a review of the literature. Earth-tide influences are not identifiable in any of the geysers we monitored. Though atmospheric-pressure influences are observed, only long-period variations on the order...
Phase derivatives and simulation of strong ground motions
D.M. Boore
2003, Bulletin of the Seismological Society of America (93) 1132-1143
Phase derivatives can be used to compute instantaneous frequency and envelope delay (also known as group delay). Envelope delay, in the guise of phase differences, has been used by engineers in the simulation of strong ground motion, particularly as a way of controlling the duration of motion. Simulations using the stochastic method, in which duration is a simple function of...
Inverse modeling of interbed storage parameters using land subsidence observations, Antelope Valley, California
J. Hoffmann, D. L. Galloway, H. A. Zebker
2003, Water Resources Research (39) 5-1-5-10
We use land-subsidence observations from repeatedly surveyed benchmarks and interferometric synthetic aperture radar (InSAR) in Antelope Valley, California, to estimate spatially varying compaction time constants, ??, and inelastic specific skeletal storage coefficients, Skv*, in a previously calibrated regional groundwater flow and subsidence model. The observed subsidence patterns reflect both the...
Inventory and review of aquifer storage and recovery in southern Florida
Ronald S. Reese
2002, Water-Resources Investigations Report 2002-4036
Aquifer storage and recovery in southern Florida has been proposed on an unprecedented scale as part of the Comprehensive Everglades Restoration Plan. Aquifer storage and recovery wells were constructed or are under construction at 27 sites in southern Florida, mostly by local municipalities or counties located in coastal areas. The...
Interactions between surface water and ground water and effects on mercury transport in the north-central Everglades
Judson W. Harvey, Steven L. Krupa, Cynthia Gefvert, Robert H. Mooney, Jungyill Choi, Susan A. King, Jefferson B. Giddings
2002, Water-Resources Investigations Report 2002-4050
The hydrology of the north-central Everglades was altered substantially in the past century by canal dredging, land subsidence, ground-water pumping, and levee construction. Vast areas of seasonal and perennial wetlands were converted to uses for agriculture, light industry, and suburban development. As the catchment area for the Everglades decreased, so...

2002, Biological Science Report 2002-0004
We collected, examined, and analyzed 1378 fish of 22 species from 47 sites in the Mississippi River basin (MRB) during 1995 and from a reference site in 1996. The sampling sites in the MRB represented National Contaminant Biomonitoring Program (NCBP) stations situated at key points on major rivers and National...

Stephen B. Smith, Anne P. Donahue, Robin J. Lipkin, Vicki Blazer, Christopher J. Schmitt, Ronald W. Goede
2002, Information and Technology Report 2002-0007
Procedures are described for processing fish for examination of external and internal anomalies and pathologies indicative of exposure to environmental contaminants and other peturbations. For the procedures described here, fish are captured (preferably by electrofishing) and held alive until processing (generally < 1 h). Fish are weighed,...

2002, Open-File Report 2004-1036
The study documented the interaction between hydrology and the biological dynamics within a single spring season at Lisbon Bottom in 1999. The study goal was to provide information necessary for resource managers to develop management strategies for this and other units of the Big Muddy National Fish and Wildlife Refuge....
Estimation of nitrogen yields and loads from basins draining to Long Island Sound, 1988–98
John R. Mullaney, Gregory E. Schwarz, Elaine C. Todd Trench
2002, Water-Resources Investigations Report 2002-4044
Monitoring data on total nitrogen concentrations and streamflow were used to estimate annual nonpoint nitrogen loads for 1988?98 at 28 monitoring sites and 26 unmonitored basins that drain to Long Island Sound. The estimated total nitrogen yields at monitoring sites were used with basin characteristics and ancillary data to develop a multiple-linear regression equation to estimate nonpoint nitrogen...

Natural and management influences on freshwater inflows and salinity in the San Francisco Estuary at monthly to interannual scales
Noah Knowles
2002, Water Resources Research (38) 25-1-25-11
Understanding the processes controlling the physics, chemistry, and biology of the San Francisco Estuary and their relation to climate variability is complicated by the combined influence on freshwater inflows of natural variability and upstream management. To distinguish these influences, alterations of estuarine inflow due to major reservoirs and freshwater pumping...
Annual primary production: Patterns and mechanisms of change in a nutrient-rich tidal ecosystem
Alan D. Jassby, James E. Cloern, B.E. Cole
2002, Limnology and Oceanography (47) 698-712
Although nutrient supply often underlies long-term changes in aquatic primary production, other regulatory processes can be important. The Sacramento-San Joaquin River Delta, a complex of tidal waterways forming the landward portion of the San Francisco Estuary, has ample nutrient supplies, enabling us to examine alternate regulatory mechanisms over...
Potential effects of global warming on the Sacramento/San Joaquin watershed and the San Francisco estuary
Noah Knowles, Daniel R. Cayan
2002, Geophysical Research Letters (29) 38-1-38-4
California's primary hydrologic system, the San Francisco estuary and its upstream watershed, is vulnerable to the regional hydrologic consequences of projected global climate change. Projected temperature anomalies from a global climate model are used to drive a combined model of watershed hydrology and estuarine dynamics. By 2090, a projected temperature...
Aerial survey methodology for bison population estimation in Yellowstone National Park
Steven C. Hess
2002, Thesis
I developed aerial survey methods for statistically rigorous bison population estimation in Yellowstone National Park to support sound resource management decisions and to understand bison ecology. Survey protocols, data recording procedures, a geographic framework, and seasonal stratifications were based on field observations from February 1998-September 2000. The reliability of this...

Grizzly bear denning chronology and movements in the Greater Yellowstone Ecosystem
Mark A. Haroldson, Mark A. Ternent, Kerry A. Gunther, Charles C. Schwartz
2002, Ursus (13) 29-38
Den entrance and emergence dates of grizzly bears (Ursus arctos) in the Greater Yellowstone Ecosystem are important to management agencies that wish to minimize impacts of human activities on bears. Current estimates for grizzly bear denning events use data that were collected from 1975–80. We update these estimates by including...
