M. E. Ikehara
1995, Open-File Report 94-494
A land-subsidence monitoring study was initiated in 1985 for the purpose of collecting data in Sacramento Valley, California, to document land-surface subsidence and to measure sediment compaction in response to ground-water pumping. Lithologic and geophysical logs obtained from the deeper of two boreholes drilled in 1987 near Woodland, California, are...

Saeid Tadayon
1995, Water-Resources Investigations Report 95-4062
Physical and chemical data were collected from four surface-water sites, six ground-water sites, and two bottom-sediment sites during 1992-93. Specific conductance, hardness, alkalinity, and dissolved- solids concentrations generally were higher in ground water than in surface water. The median concentrations of dissolved major ions, with the exception of potassium, were...
Spring-summer survival rates of yearling versus adult mallard females
Ronald E. Reynolds, Robert J. Blohm, James D. Nichols, James E. Hines
1995, Journal of Wildlife Management (59) 691-696
Knowledge of the timing, magnitude, and cause of mortality in wildlife populations is imperative for developing management strategies that protect or improve the status of these populations. Age- and sex-specific population parameter estimates provide the most useful information for this purpose. Numerous studies have provided information about survival rates in...
Spring-staging ecology of midcontinent greater white-fronted geese
Gary Krapu, Kenneth J. Reinecke, Dennis G. Jorde, S. Gay Simpson
1995, Journal of Wildlife Management (59) 736-746
A major part of the midcontinent greater white-fronted goose (Anser albifrons) population stages for several weeks in spring in the Rainwater Basin Area (RBA) of south-central Nebraska where substantial mortality from disease occurs periodically. Effective management of this population requires better data on use of habitat, vulnerability to disease, and...
Age-class separation of blue-winged ducks
William L. Hohman, Joseph L. Moore, Daniel J. Twedt, John G. Mensik, E. Logerwell
1995, Journal of Wildlife Management (59) 727-735
Accurate determination of age is of fundamental importance to population and life history studies of waterfowl and their management. Therefore, we developed quantitative methods that separate adult and immature blue-winged teal (Anas discors), cinnamon teal (A. cyanoptera), and northern shovelers (A. clypeata) during spring and summer. To assess suitability of...
Geographic variation in band reporting rates for mallards based on reward banding
James D. Nichols, Ronald E. Reynolds, Robert J. Blohm, Robert E. Trost, James E. Hines, Judith P. Bladen
1995, Journal of Wildlife Management (59) 697-708
We conducted a reward band study on mallards (Anas platyrhynchos) to estimate and test hypotheses about sources of variation in band reporting rate. We banded 25,398 mallards with standard and 100 reward bands (3 mallards banded with standard bands for every reward-banded mallard) during preseason (Jul-Sep), 1988. We used a...

Michael J. Walter, Thomas W. Sisson, Dean C. Presnall
1995, Earth and Planetary Science Letters (135) 77-90
We present a method for calculating quantitative melting reactions in systems with multiple solid solutions that accounts for changes in the mass proportions of phases between two points at different temperatures along a melting curve. This method can be applied to any data set that defines the phase proportions along...

1995, Miscellaneous Field Studies Map 2284
The Mississippi Embayment regional seismic hazard (Fuller, 1912; Nuttli, 1973, 1982, 1983), associated with the New Madrid seismic zone (NMSZ) is attributed to displacement on seismogenic structures primarily within the failed Reelfoot rift (Burke and Dewey, 1973; Ervin and McGinnis, 1975; Hildenbrand, 1977; Johnston and Shedlock, 1992). Hildenbrand and others...

Yansen Wang, David R. Miller, Dean E. Anderson, Michael L. McManus
1995, Agricultural and Forest Meteorology (76) 277-291
An aerial spray droplets' transport model has been developed by applying recent advances in Lagrangian stochastic simulation of heavy particles. A two-dimensional Lagrangian stochastic model was adopted to simulate the spray droplet dispersion in atmospheric turbulence by adjusting the Lagrangian integral time scale along the drop trajectory. The other major...
