Present and Reference Concentrations and Yields of Suspended Sediment in Streams in the Great Lakes Region and Adjacent Areas
Dale M. Robertson, David A. Saad, Dennis M. Heisey
2006, Scientific Investigations Report 2006-5066
In-stream suspended sediment and siltation and downstream sedimentation are common problems in surface waters throughout the United States. The most effective way to improve surface waters impaired by sediments is to reduce the contributions from human activities rather than try to reduce loadings from natural sources. Total suspended sediment/solids (TSS)...
Ballast water research at the WFRC
Lyman Thorsteinson
2006, Fact Sheet 2006-3080
Invasive aquatic species are considered to be one of the greatest threats to marine biodiversity, coastal economies, and even human health. Ballast water is a primary vector for these bioinvasions. One method of reducing risk of ballast water introductions is mid-ocean exchange of marine ballast water. However, it is widely...
Status of Water Levels and Selected Water-Quality Conditions in the Mississippi River Valley Alluvial Aquifer in Eastern Arkansas, 2004
T. P. Schrader
2006, Scientific Investigations Report 2006-5128
During the spring of 2004, water levels were measured in 684 wells completed in the Mississippi River Valley alluvial aquifer in eastern Arkansas. Ground-water levels are affected by intense ground-water withdrawals resulting in extensive potentiometric depressions. In 2004, the highest water-level altitude measured was 293 feet above National Geodetic Vertical...
BLM Density Management and Riparian Buffer Study: Establishment Report and Study Plan
John H. Cissel, P. D. Anderson, Deanna H. Olson, Klaus Puettmann, Shanti Berryman, Samuel Chan, Charley Thompson
2006, Scientific Investigations Report 2006-5087
The Bureau of Land Management (BLM), Pacific Northwest Research Station (PNW), U.S. Geological Survey (USGS), and Oregon State University (OSU) established the BLM Density Management and Riparian Buffer Study (DMS) in 1994 to demonstrate and test options for young stand management to meet Northwest Forest Plan objectives in western Oregon....
Real-time seismic monitoring of the new Cape Girardeau Bridge and preliminary analyses of recorded data: An overview
Mehmet Celebi
2006, Earthquake Spectra (22) 609-630
This paper introduces the state-of-the-art seismic monitoring system implemented for the 1,206-m-long (3,956 ft) cable-stayed Bill Emerson Memorial Bridge in Cape Girardeau (Missouri), a new Mississippi River crossing, approximately 80 km from the epicentral region of the 1811 and 1812 New Madrid earthquakes. The real-time seismic monitoring system for the bridge includes a...
Spectral mixture analyses of hyperspectral data acquired using a tethered balloon
Xuexia Chen, Lee Vierling
2006, Remote Sensing of Environment (103) 338-350
Tethered balloon remote sensing platforms can be used to study radiometric issues in terrestrial ecosystems by effectively bridging the spatial gap between measurements made on the ground and those acquired via airplane or satellite. In this study, the Short Wave Aerostat-Mounted Imager (SWAMI) tethered balloon-mounted platform was utilized to evaluate...
Autoinducer 2: a concentration-dependent signal for mutualistic bacterial biofilm growth
A.H. Rickard, R.J. Palmer Jr., David S. Blehert, S.R. Campagna, M.F. Semmelhack, P.G. Egland, B.L. Bassler, P.E. Kolenbrander
2006, Molecular Microbiology (60) 1446-1456
4,5-dihydroxy-2,3-pentanedione (DPD), a product of the LuxS enzyme in the catabolism of S-ribosylhomocysteine, spontaneously cyclizes to form autoinducer 2 (AI-2). AI-2 is proposed to be a universal signal molecule mediating interspecies communication among bacteria. We show that mutualistic and abundant biofilm growth in flowing saliva of two human oral commensal bacteria, Actinomyces...

Introduction of translation stop condons into the viral glycoprotein gene in a fish DNA vaccine eliminates induction of protective immunity
Kyle A. Garver, Carla M. Conway, Gael Kurath
2006, Marine Biotechnology (8) 351-356
A highly efficacious DNA vaccine against a fish rhabdovirus, infectious hematopoietic necrosis virus (IHNV), was mutated to introduce two stop codons to prevent glycoprotein translation while maintaining the plasmid DNA integrity and RNA transcription ability. The mutated plasmid vaccine, denoted pIHNw-G2stop, when injected intramuscularly into fish at high doses, lacked...
Biostratigraphic and lithologic correlations of two Sonoma County Water Agency pilot wells with the type Wilson Grove Formation, Sonoma County, central California
Charles L. Powell II, Robert J. McLaughlin, Elmira Wan
2006, Open-File Report 2006-1196
Small mollusk faunas characteristic of the uppermost part of the Wilson Grove Formation at Wilson Grove and along River Road at Trenton (Pliocene) were encountered in Sonoma County Water Agency pilot wells at Occidental Road well field between 320-500 ft (98-152 m), depth, and in the Sebastopol Road pilot well...
State-parameter estimation of ecosystem models using a smoothed ensemble Kalman filter
M. Chen, Shuguang Liu, Larry L. Tieszen
2006, Conference Paper, Proceedings of the iEMSs 2006 conference
Much of the effort in data assimilation methods for carbon dynamics analysis has focused on estimating optimal values for either model parameters or state variables. The main weakness of estimating parameter values alone (i.e., without considering state variables) is that all errors from input, output, and model structure are attributed...
Volcanic hazards at Atitlan volcano, Guatemala
J.M. Haapala, R. Escobar Wolf, James W. Vallance, William I. Rose Jr., J.P. Griswold, S. P. Schilling, J.W. Ewert, M. Mota
2006, Open-File Report 2005-1403
Atitlan Volcano is in the Guatemalan Highlands, along a west-northwest trending chain of volcanoes parallel to the mid-American trench. The volcano perches on the southern rim of the Atitlan caldera, which contains Lake Atitlan. Since the major caldera-forming eruption 85 thousand years ago (ka), three stratovolcanoes--San Pedro, Toliman, and Atitlan--have...
