P.K. Sims
2009, Circular 1334
Recognition of a major Precambrian continental-scale, two-stage conjugate strike-slip fault system - here designated as the Trans-Rocky Mountain fault system - provides new insights into the architecture of the North American continent. The fault system consists chiefly of steep linear to curvilinear, en echelon, braided and branching ductile-brittle shears and...
Sample project: establishing a global forest monitoring capability using multi-resolution and multi-temporal remotely sensed data sets
Matt Hansen, Steve Stehman, Tom Loveland, Jim Vogelmann, Mark Cochrane
2009, The NASA LCLUC Program: an interdisciplinary approach to studying land-cover and land-use change 3-3
Quantifying rates of forest-cover change is important for improved carbon accounting and climate change modeling, management of forestry and agricultural resources, and biodiversity monitoring. A practical solution to examining trends in forest cover change at global scale is to employ remotely sensed data. Satellite-based monitoring of forest cover can be...
Pelagic habitat visualization: the need for a third (and fourth) dimension: HabitatSpace
C J Beegle-Krause J, Tiffany Vance, Debbie Reusser, David Stuebe, Eoin Howlett
2009, Conference Paper, Estuarine and coastal modeling : proceedings of the eleventh international conference, November 4-6, 2009, Seattle, Washington
Habitat in open water is not simply a 2-D to 2.5-D surface such as the ocean bottom or the air-water interface. Rather, pelagic habitat is a 3-D volume of water that can change over time, leading us to the term habitat space. Visualization and analysis in 2-D is well supported...

Application of the multi-dimensional surface water modeling system at Bridge 339, Copper River Highway, Alaska
Timothy P. Brabets, Jeffrey S. Conaway
2009, Open-File Report 2009-1237
The Copper River Basin, the sixth largest watershed in Alaska, drains an area of 24,200 square miles. This large, glacier-fed river flows across a wide alluvial fan before it enters the Gulf of Alaska. Bridges along the Copper River Highway, which traverses the alluvial fan, have been impacted by channel...
Inversion of multichannel geophysical data with projected kernels
M. Andy Kass, Trevor P. Irons, Yaoguo Li
2009, Conference Paper, SEG technical program expanded abstracts 2009
Statistical de‐noising methods such as Principal Component Analysis modify data in a way not constrained by physics. In much the same way as frequency‐filtered data must incorporate altered frequency content into numerical interpretation, so must statistically rotated data include the rotation operator in inversion processes. We propose a method of...
Development of an objective‐oriented groundwater model for conjunctive‐use planning of surface water and groundwater
Yung-Chia Chiu, Ne-Zheng Sun, Tracy Nishikawa, William W.-G. Yeh
2009, Water Resources Research (45)
In this paper we construct an objective‐oriented model for conjunctive‐use planning of surface water and groundwater for the Warren groundwater basin in southern California. The goal of conjunctive‐use planning is to decrease high‐nitrate concentration while maintaining groundwater levels at desired elevations and meeting water demand. We formulate a management problem...

Abigail J. Darrah, David G. Krementz
2009, Journal of Wildlife Management (73) 1380-1386
The migratory population of the king rail (Rallus elegans) has declined dramatically during the past 40 years, emphasizing the need to identify habitat requirements of this species to help guide conservation efforts. To assess distribution and habitat use of king rails along the Illinois and Upper Mississippi valleys, USA, we...
Shifts in the trophic base of intermittent stream food webs
Matthew P. Dekar, Daniel D. Magoulick, G.R. Huxel
2009, Hydrobiologia (635) 263-277
Understanding spatial and temporal variation in the trophic base of stream food webs is critical for predicting population and community stability, and ecosystem function. We used stable isotope ratios (13C/12C, and 15N/14N) to characterize the trophic base of two streams in the Ozark Mountains of northwest Arkansas, U.S.A. We predicted...

Lisa A. Morgan, Pat Shanks, Kenneth L. Pierce
2009, Special Paper of the Geological Society of America (459)
Hydrothermal explosions are violent and dramatic events resulting in the rapid ejection of boiling water, steam, mud, and rock fragments from source craters that range from a few meters up to more than 2 km in diameter; associated breccia can be emplaced as much as 3 to 4 km from...
Reassessment of the predatory effects of rainbow smelt on ciscoes in Lake Superior
Jared T. Myers, Michael L. Jones, Jason D. Stockwell, Daniel L. Yule
2009, Transactions of the American Fisheries Society (138) 1352-1368
Evidence from small lakes suggests that predation on larval ciscoes Coregonus artedi by nonnative rainbow smelt Osmerus mordax can lead to cisco suppression or extirpation. However, evidence from larger lakes has led to equivocal conclusions. In this study, we examine the potential predation effects of rainbow smelt in two adjacent but contrasting embayments in...

Amie M. G. Brady, Rebecca N. Bushon, Erin E. Bertke
2009, Scientific Investigations Report 2009-5222
Water quality at beaches is monitored for fecal indicator bacteria by traditional, culture-based methods that can take 18 to 24 hours to obtain results. A rapid detection method that provides estimated concentrations of fecal indicator bacteria within 1 hour from the start of sample processing would allow beach managers to...
Predicting recreational water quality using turbidity in the Cuyahoga River, Cuyahoga Valley National Park, Ohio, 2004-7
Amie M. G. Brady, Rebecca N. Bushon, Meg B. Plona
2009, Scientific Investigations Report 2009-5192
The Cuyahoga River within Cuyahoga Valley National Park (CVNP) in Ohio is often impaired for recreational use because of elevated concentrations of bacteria, which are indicators of fecal contamination. During the recreational seasons (May through August) of 2004 through 2007, samples were collected at two river sites, one upstream of...

These range from the residence time of sediment and contaminants to nutrient uptake and larval retention and dispersal. As currents approach a coast they diverge...
Community exposure to lahar hazards from Mount Rainier, Washington
Nathan J. Wood, Christopher E. Soulard
2009, Scientific Investigations Report 2009-5211
Geologic evidence of past events and inundation modeling of potential events suggest that lahars associated with Mount Rainier, Washington, are significant threats to downstream development. To mitigate potential impacts of future lahars and educate at-risk populations, officials need to understand how communities are vulnerable to these fast-moving debris flows and...
