Two electromagnetic surface geophysical techniques were used to explore the ground-water resources of Isla de Mona, Puerto Rico—a 55-square-kilometer island located between Puerto Rico and Hispañiola, Isla de Mona is a tectonically uplifted carbonate plateau of Neogene age that has an average elevation of about 50 meters above mean...
Surface seismic and electrical methods to detect fluids related to faulting
Donna Eberhart-Phillips, William D. Stanley, Brian D. Rodriguez, William J. Lutter
1995, Journal of Geophysical Research Solid Earth (100) 12919-12936
In the absence of drilling, surface-based geophysical methods are necessary to observe fault zones and fault zone physical properties at seismogenic depths. These in situ physical properties can then be used to infer the presence and distribution of fluids along faults, although such observations are by nature indirect and become...
Banding reference areas and survival rates of green-winged teal, 1950-1989
Diane S. Chu, James D. Nichols, Jay B. Hestbeck, James E. Hines
1995, Journal of Wildlife Management (59) 487-498
The green-winged teal (Anas crecca carolinensis) is an important harvest species, yet we know relatively little about its population ecology. We investigated aspects of green-winged teal population ecology of potential importance to waterfowl managers. We used recoveries of green-winged teal banded during winter (1950-89) to establish banding reference areas and...
Use of solicited bands and separation of hunting and natural mortality: a comment
Michael J. Conroy, James E. Hines, B. Kenneth Williams
1995, Journal of Wildlife Management (59) 619-621
We previously presented (Conroy 1985, Conroy et al. 1989) models for analysis of band recovery data stratified into those voluntarily reported and those obtained by solicitation, similar to models described by Pollock et al. (1994). We discuss differences between the 2 modeling approaches and suggest designs and analyses involving...

Steven V. Fend, James L. Carter
1995, Journal of Freshwater Ecology (10) 343-359
Floating chironomid pupal exuviae were collected throughout the Yakima River (Washington, USA) and tributaries in 1989 and 1990. All samples were taken during the October-November low-flow season and most sites were visited once with a sampling effort of approximately 10 minutes. Sampled stream segments ranged from 3rd to 7th order...

1995, Open-File Report 94-365
Surface-water-quality conditions and trends were assessed in the lower Kansas River Basin, which drains about 15,300 square miles of mainly agricultural land in southeast Nebraska and northeast Kansas. On the basis of established water-quality criteria, most streams in the basin were suitable for uses such as public-water supply, irrigation, and...

1995, Water-Resources Investigations Report 94-4094
Multivariate analyses of fish-community, water- quality, streambed-sediment-quality, and habitat data collected from 1982 through 1984 in the Fox, Des Plaines, and Du Page River Basins in northeastern Illinois indicate that fish-community structure was strongly related to water-quality gradients commonly associated with differences between agricultural and urban land uses. Detrended correspondence...

Review of sediment data in the South Platte River Basin, Colorado, 1980-92
Janet S. Heiny
1995, Fact Sheet 153-95
Suspended-sediment transport and its relation to water quality are important issues in the South Platte River Basin. Most sediment enters the South Platte River during snowmelt runoff from March to June. The suspended sediment varies by particle size, concentration, and load. Suspended-sediment data in the South Platte River for water...
Wind shear stress measurements in a coastal marsh during Hurricane Andrew
J. R. Dingler, S.A. Hsu, A. Lee Foote
1995, Journal of Coastal Research 295-305
Hurricane Andrew produced changes to the Louisiana wetlands not normally observed after lesser, more common storms. For example, the <25 m/s wind speeds generated by cold fronts and winter storms, and any accompanying storm surge, do not cause substantial, wide-spread alteration of marsh vegetation. During Hurricane Andrew, however, the wind,...
