A longitudinal assessment of the aquatic macroinvertebrate community in the channelized lower Missouri River
Barry C. Poulton, Mark L. Wildhaber, Collette S. Charbonneau, James F. Fairchild, Brad G. Mueller, Christopher J. Schmitt
2003, Environmental Monitoring and Assessment (85) 23-53
We conducted an aquatic macroinvertebrate assessment in the channelized reach of the lower Missouri River, and used statistical analysis of individual metrics and multimetric scores to identify community response patterns and evaluate relative biological condition. We examined longitudinal site differences that are potentially associated with water qualityrelated factors originating from...
Sediment dynamics of a sediment-starved, open-marine marsh embayment: Waccasassa Bay, Florida
Nathan J. Wood, Albert C. Hine
2003, Journal of Coastal Research (19) 574-583
Although the Big Bend region of Florida's Gulf of Mexico coast is considered sediment-starved, the open marine marshes that characterize the area are keeping pace with sea level rise. Waccasassa Bay, an embayment within this region, also contains unique subtidal mudbanks that thicken with increasing proximity to embayment head,...

The metallogenic belts and locations of major mineral deposits of Northeast Asia are portrayed on Sheets 1-4. Sheet 1 portrays the location of significant lode deposits and placer districts at a scale of 1:7,500,000. Sheets 2-4 portray the metallogenic belts of the region in a series of 12 time-slices from...

L.G. Bergfeld, D. H. Schoellhamer
2003, Interagency Ecological Program Newsletter 5-12
Salinity and temperature are crucial state variables affecting estuarine habitat an d, thus, are measured by various San Francisco Estuary programs. This article presents a comparison of salinity and temperature data collected at seven continuo us monitoring stations throughout San Francisco Bay (Figure 1) with data collected monthly by the...

2003, Open-File Report 2003-203
This is the Web version of a CD-ROM publication. This report consists of summary major compilations and syntheses accomplished in the six-year project through April 2003 for the study on the Mineral Resources, Metallogenesis, and Tectonics of Northeast Asia (Eastern and Southern Siberia, Mongolia, Northeastern China, South Korea, and Japan)....
Hydrogeology and Ground-Water Quality of Brunswick County, North Carolina
Stephen L. Harden, Jason M. Fine, Timothy B. Spruill
2003, Water-Resources Investigations Report 2003-4051
Brunswick County is the southernmost coastal county in North Carolina and lies in the southeastern part of the Coastal Plain physiographic province. In this report, geologic, hydrologic, and chemical data were used to investigate and delineate the hydrogeologic framework and ground-water quality of Brunswick County. The major aquifers and their...
Geologic database for digital geology of California, Nevada, and Utah— An application of the North American Data Model
David R. Bedford, Steve Ludington, Constance M. Nutt, Paul A. Stone, David M. Miller, Robert J. Miller, David L. Wagner, George J. Saucedo
2003, Open-File Report 2003-135
The USGS is creating an integrated national database for digital state geologic maps that includes stratigraphic, age, and lithologic information. The majority of the conterminous 48 states have digital geologic base maps available, often at scales of 1:500,000. This product is a prototype, and is intended to demonstrate the types...
Measurement of sedimentary interbed hydraulic properties and their hydrologic influence near the Idaho Nuclear Technology and Engineering Center at the Idaho National Engineering and Environmental Laboratory
Kim S. Perkins
2003, Water-Resources Investigations Report 2003-4048
Disposal of wastewater to unlined infiltration ponds near the Idaho Nuclear Technology and Engineering Center (INTEC), formerly known as the Idaho Chemical Processing Plant, at the Idaho National Engineering and Environmental Laboratory (INEEL) has resulted in the formation of perched water bodies in the unsaturated zone (Cecil and others, 1991)....
Use of a probabilistic neural network to reduce costs of selecting construction rock
Donald A. Singer, James D. Bliss
2003, Natural Resources Research (12) 135-140
Rocks used as construction aggregate in temperate climates deteriorate to differing degrees because of repeated freezing and thawing. The magnitude of the deterioration depends on the rock's properties. Aggregate, including crushed carbonate rock, is required to have minimum geotechnical qualities before it can be used in asphalt and concrete. In...
Assessment of habitat and streamflow requirements for habitat protection, Usquepaug–Queen River, Rhode Island, 1999–2000
David S. Armstrong, Gene W. Parker
2003, Open-File Report 2002-438
The relations among stream habitat and hydrologic conditions were investigated in the Usquepaug–Queen River Basin in southern Rhode Island. Habitats were assessed at 13 sites on the mainstem and tributaries from July 1999 to September 2000. Channel types are predominantly low-gradient glides, pools, and runs that have a sand and...
Uncertainty in spatially explicit animal dispersal models
Wolf M. Mooij, Donald L. DeAngelis
2003, Ecological Applications (13) 794-805
Uncertainty in estimates of survival of dispersing animals is a vexing difficulty in conservation biology. The current notion is that this uncertainty decreases the usefulness of spatially explicit population models in particular. We examined this problem by comparing dispersal models of three levels of complexity: (1) an event-based binomial model...
A gentic survey of Salvinia minima in the southern United States
Paul T. Madeira, Colette C. Jacono, Phil Tipping, Thai K. Van, Ted D. Center
2003, Aquatic Botany (76) 127-139
The genetic relationships among 68 samples of Salvinia minima (Salviniaceae) were investigated using RAPD analysis. Neighbor joining, principle components, and AMOVA analyses were used to detect differences among geographically referenced samples within and outside of Florida. Genetic distances (Nei and Li) range up to 0.48, although most are under 0.30, still relatively...

2003, Open-File Report 2003-211
The February 28, 2001, Nisqually, Washington, earthquake (Mw = 6.8) damaged an area of the northwestern United States that previously experienced two major historical earthquakes, in 1949 and in 1965. Preliminary estimates of direct monetary losses from damage due to earthquake-induced landslides is approximately $34.3 million. However, this figure does...
