Combined use of borehole geophysics and packers to site potable wells in a contaminated area in Montville, Connecticut
A. Green, John W. Lane Jr., Carole D. Johnson, John Williams, Remo A. Mondazzi, Peter K. Joesten
2004, Conference Paper, Proceedings: 2004 U.S. EPA/NGWA Fractured Rock Conference
A leaking underground gasoline tank contaminated a crystalline bedrock aquifer in Montville, Connecticut, USA with MTBE and benzene. At the original residential bedrock supply wells, the median MTBE concentration was 165 micrograms per liter (mg/L), and the median benzene concentration was 320 mg/L. The maximum concentrations of MTBE and...
Time-series monitoring in fractured-rock aquifers
Carole D. Johnson, John W. Lane Jr., Frederick D. Day-Lewis
2004, Conference Paper, Proceedings: 2004 U.S. EPA/NGWA fractured rock conference: State of the science and measuring success in remediation
Time-lapse monitoring of subsurface processes is an emerging and promising area of hydrogeophysics. The combined use of non-invasive or minimally invasive geophysical methods with hydraulic and geochemical sampling is a cost-effective approach for aquifer characterization, long-term aquifer monitoring, and remediation monitoring. Time-lapse geophysical surveys can indirectly measure time-varying hydrologic parameters...
Global climate change and wildlife in North America
D.B. Inkley, Michael G. Anderson, Andrew R Blaustein, Virginia Burkett, Benjamin Felzer, Brad Griffith, Jeff Price, Terry L. Root
2004, Technical Review 04-2
It is widely accepted by the scientific community that the earth, which has always experienced climate variation, is now undergoing a period of rapid climate change that is enhanced by anthropogenic atmospheric carbon enrichment during the past 100 years. These climatic changes are accelerating and projections for the next 100 years indicate extensive warming in most...
Light attenuation profiling as an indicator of structural changes in coastal marshes
Elijah Ramsey III, Gene Nelson, Frank Baarnes, R. Spell
2004, Book chapter, Remote sensing and GIS accuracy assessment
To best respond to natural and human-induced stresses, resource managers and researchers require remote sensing techniques that can map the biophysical characteristics of natural resources on regional and local scales. The implementation of advanced measurement techniques would provide significant improvements in the quantity, quality, and timeliness of biophysical data useful...

Constraints on the geological history of the karst system in Southern Missouri, U.S.A. provided by radiogenic, cosmogenic and physical/chemical characteristics of doline fill
David J. Waery, Richard W. Harrison, Robert B. Jacobson, Milan P. Javich, Shannon A. Mahan, David Wronkiewicz
2004, Acta Carsologica (33) 207-217
The Ozark Plateaus region of southern Missouri is underlain by dominantly carbonate marine platform rocks of Paleozoic age. The region has been sub-aerially exposed since the late Paleozoic and is characterized by extensive karst. To better understand the geologic history of this regional karst system, we examined the stratigraphic record...

Deciphering multiple Mesoproterozoic and Paleozoic events recorded in zircon and titanite from the Baltimore Gneiss, Maryland: SEM imaging, SHRIMP U-Pb geochronology, and EMP analysis
John N. Aleinikoff, J. Wright Horton, Jr., Avery A. Drake Jr., R. P. Wintsch, C.M. Fanning, K. Yi
2004, Memoir of the Geological Society of America (197) 411-434
The Baltimore Gneiss, exposed in antiforms in the eastern Maryland Piedmont, consists of a suite of felsic and mafic gneisses of Mesoproterozoic age. Zircons from the felsic gneisses are complexly zoned, as shown in cathodoluminescence imaging; most zircon grains have multiple overgrowth zones, some of which are adjacent and parallel to elongate cores. Sensitive high-resolution ion microprobe...

Summary of water quality trends in the Connecticut River, 1968-1998
John R. Mullaney
2004, Book chapter, The Connecticut River ecological study (1965-1973) revisited: Ecology of the Lower Connecticut River 1973-2003
The Connecticut River has a long history of water quality impairment. From the 1800s to the late 1960s, untreated or minimally treated waste discharges from population centers and industries have caused serious water quality problems. Trend analysis of selected water quality data in Connecticut from 1968 to 1998, collected by...

Acidity and alkalinity in mine drainage: Theoretical considerations
Carl S. Kirby, Charles A. Cravotta III,
2004, Conference Paper, Proceedings America Society of Mining and Reclamation, 2004
Acidity, net acidity, and net alkalinity are widely used parameters for the characterization of mine drainage, but these terms are not well defined and are often misunderstood. Incorrect interpretation of acidity, alkalinity, and derivative terms can lead to inadequate treatment design or poor regulatory decisions. We briefly explain derivations of...
Origin of the Bering Sea salient
J.M. Amato, J. Toro, Thomas E. Moore
2004, GSA Special Papers (383) 131-144
Our investigations in Alaska and Russia show that the curved orogen of the Bering Strait region is a composite feature that formed as a result of multiple superimposed events and cannot be related to latest Cretaceous–early Tertiary east-west shortening. Relations interpreted to record east-west shortening include the Chukchi syntaxis, deformation...
The legacy of contaminated sediments in Boston Harbor
Frank T. Manheim
2004, Report
Scientists at the U.S. Geological Survey (USGS) have assembled a significant body of data that is now in a usable form. The USGS adopted an interdisciplinary approach to begin the pioneering effort at data rescue. This work involved collaboration with the Environmental Protection Agency (EPA), the U.S....
Using Forward Looking Infrared (FLIR) imagery to detect polar bear maternal dens: Operations manual
Geoffrey S. York, Steven C. Amstrup, Kristin S. Simac
2004, BOEM MMS 2004-062
Recent research has shown that Forward Looking Infia-Red (FLIR) imagery can detect polar bear dens despite total snow cover over their deming habitat. FLIR imagers detect a AT or difference in temperature between objects in the imager's field of view. During the Arctic winter, the groundlsnow surface is typically cold,...
Acidity and Alkalinity in mine drainage: Practical considerations
III Cravotta, Carl S. Kirby
2004, Conference Paper, Proceedings America Society of Mining and Reclamation
In this paper, we emphasize that the Standard Method hot peroxide treatment procedure for acidity determination (hot acidity) directly measures net acidity or net alkalinity, but that more than one water-quality measure can be useful as a measure of the severity of acid mine drainage. We demonstrate that the hot...
Strength and acoustic properties of Ottawa sand containing laboratory-formed methane gas hydrate
William J. Winters, William F. Waite, David H. Mason
2004, Book chapter, Advances in the study of gas hydrates
Although gas hydrate occurs in a wide variety of sediment types and is present and even pervasive at some locations on continental margins, little is known about how it forms naturally. Physical properties of the resultant gas hydrate-sediment mixtures, data needed for input into models that predict location and quantity...

The depositional history of three freshwater lakes in north central Florida: Brooklyn Lake, Levy's Prairie, and Cowpen Lake
Nancy T. DeWitt
2004, Thesis
Florida has approximately 7800 lakes that are heavily concentrated in the north-central part of the state—a mantled karst terrain. Although much research has been conducted in Florida’s lakes, there is not much information on the sedimentary infill. The focus of this research is to define the sedimentary infill of three...
