P.B. Hatzinger, John Karl Bohlke, N.C. Sturchio, B. Gu, L.J. Heraty, R.C. Borden
2009, Environmental Chemistry (6) 44-52
An in situ experiment was performed in a shallow alluvial aquifer in Maryland to quantify the fractionation of stable isotopes in perchlorate (Cl and O) and nitrate (N and O) during biodegradation. An emulsified soybean oil substrate that was previously injected into this aquifer provided the electron donor necessary for...

2009, Book, 10th International HCH and pesticide forum book of papers: how many obsolete pesticides have been disposed of 8 years after signature of Stockholm Convention
The Khorezm province in northwest Uzbekistan is a productive agricultural area within the Aral Sea Basin that produces cotton, rice and wheat. Various organochlorine pesticides were widely used for cotton production before Uzbekistan's independence in 1991. In Khorezm, small lakes have formed in natural depressions that receive inputs mostly from...

Quantifying the spatial and temporal dynamics of carbon stocks in terrestrial ecosystems and carbon fluxes between the terrestrial biosphere and the atmosphere is critical to our understanding of regional patterns of carbon storage and loss. Here we use the General Ensemble Biogeochemical Modeling System to simulate the terrestrial ecosystem carbon...

The Great Lakes Science Center of the United States Geological Survey (USGS) is working cooperatively with the Ontario Ministry of Natural Resources (OMNR) on a threeyear study to develop standard procedures for acoustic and midwater trawl (AC-MT) assessments of spawning cisco Coregonus artedi that the OMNR can carry forward as...
Efficacy of automatic vocalization recognition software for anuran monitoring
J. Hardin Waddle, Tyler F. Thigpen, Brad M. Glorioso
2009, Herpetological Conservation and Biology (4) 384-388
Surveys of vocalizations are a widely used method for monitoring anurans, but it can be difficult to coordinate standardized data collection across a large geographic area. Digital automated recording systems (ARS) offer a low-cost method for obtaining samples of anuran vocalizations, but the number of recordings can...

2009, Computers & Geosciences (35) 2304-2313
Spacecraft continue to send back extraordinary amounts of data from Mars leaving scientists with the considerable task of analyzing an ever-increasing wealth of information. There are abundant uses for coregistered topography and images, but coregistering various datasets can be time-consuming and labor-intensive. We have developed a set of C-shell Unix...

Direct calculation of the probability distribution for earthquake losses to a portfolio
Robert L. Wesson, David M. Perkins, Nico Luco, Erdem Karaca
2009, Earthquake Spectra (25) 687-706
We demonstrate a direct method for the calculation of the annual frequency of exceedance for earthquake losses (or the probability distribution for annual losses) to a portfolio. This method parallels the classic method of probabilistic seismic hazard analysis for the calculation of the annual frequency of exceedance for earthquake ground...

2009, Conference Paper, Field trip guidebook: New York State Geological Association 81st annual meeting, September 25-27, 2009
In this field trip, we provide a review of the significant controversy concerning the timing of deglaciation in the Hudson and Wallkill Valleys. We outline the differences in methodology and chronology with a circular route throughout the Hudson and Wallkill valleys. We begin the trip at Lake Mohonk near New...
Distribution of major anions and trace elements in the unsaturated zone at Franklin Lake Playa, California, USA
George N. Breit, Harland L. Goldstein, Richard L. Reynolds, James C. Yount
2009, Natural Resources and Environmental Issues (15)
The composition of surficial salts formed near dry and drying saline lakes are partly the product of processes active in the unsaturated zone between the ground surface and the water table. These processes were investigated by determining the abundance of water-extractable solutes in sediment from the ground surface to the...

Zoogeography, conservation, and ecology of crayfishes within the Cheat River basin of the Upper Monongehela River drainage, West Virginia
Stuart A. Welsh
2009, Proceedings of the West Virginia Academy of Science (81) 25-40
During summer 2008, we studied the geographic distribution and conservation status of crayfishes within the Cheat River basin of the upper Monongahela River drainage. Stream sites (n = 73) were selected with a probabilistic sampling design, whereas one reservoir (Cheat Lake) and seven terrestrial sites for burrowing crayfishes were selected...

Harvey E. Belkin, R. MacDonald, F. Wall, B. Baginski
2009, Mineralogical Magazine (73) 777-796
Electron microprobe analyses are presented of chevkinite-group minerals from Canada, USA, Guatemala, Norway, Scotland, Italy and India. The host rocks are metacarbonates, alkaline and subalkaline granitoids, quartz-bearing pegmatites, carbonatite and an inferred K-rich tuff. The analyses extend slightly the range of compositions in the chevkinite group, e.g. the most...

Constraints on the stress state of the San Andreas fault with analysis based on core and cuttings from SAFOD drilling phases 1 and 2
Cheryl Tembe, David A. Lockner, Teng-fong Wong
2009, Journal of Geophysical Research - Solid Earth (114)
Analysis of field data has led different investigators to conclude that the San Andreas Fault (SAF) has either anomalously low frictional sliding strength (μ < 0.2) or strength consistent with standard laboratory tests (μ > 0.6). Arguments for the apparent weakness of the SAF generally hinge on conceptual models involving intrinsically weak...
Advanced Tools for River Science: EAARL and MD_SWMS: Chapter 3

2009, Report, PNAMP Special Publication: Remote Sensing Applications for Aquatic Resource Monitoring
Disruption of flow regimes and sediment supplies, induced by anthropogenic or climatic factors, can produce dramatic alterations in river form, vegetation patterns, and associated habitat conditions. To improve habitat in these fluvial systems, resource managers may choose from a variety of treatments including flow and/or sediment prescriptions, vegetation management, or...
