Kristen Hart, David G. Zawada, Ikuko Fujisaki, Barbara H. Lidz
2013, Biological Conservation (161) 142-154
Use of existing marine protected areas (MPAs) by far-ranging marine turtles can be determined using satellite telemetry. Because of a lack of information on MPA use by marine turtles in the Gulf of Mexico, we used satellite transmitters in 2010 and 2011 to track movements of 11 adult female breeding...

Colloid transport in saturated porous media: Elimination of attachment efficiency in a new colloid transport model
Lee L. Landkamer, Ronald W. Harvey, Timothy D. Scheibe, Joseph N. Ryan
2013, Water Resources Research (49) 2952-2965
A colloid transport model is introduced that is conceptually simple yet captures the essential features of colloid transport and retention in saturated porous media when colloid retention is dominated by the secondary minimum because an electrostatic barrier inhibits substantial deposition in the primary minimum. This model is based on conventional...
Seasonal comparison of aquatic macroinvertebrate assemblages in a flooded coastal freshwater marsh
Sung-Ryong Kang, Sammy L. King
2013, Open Journal Of Ecology (3) 94-101
Marsh flooding and drying may be important factors affecting aquatic macroinvertebrate density and distribution in coastal freshwater marshes. Limited availability of water as a result of drying in emergent marsh may decrease density, taxonomic diversity, and taxa richness. The principal objectives of this study are to characterize the seasonal aquatic...

Frederick Pollitz, Aaron G. Wech, Honn Kao, Roland Burgmann
2013, Journal of Geophysical Research B: Solid Earth (118) 2445-2459
Two catalogs of episodic tremor events in northern Cascadia, one from 2006 to 2012 and the other from 1997 to 2011, reveal two systematic patterns of tremor occurrence in southern Vancouver Island: (1) most individual events tend to occur in the third quarter of the year; (2) the number of...
Reconstructing satellite images to quantify spatially explicit land surface change caused by fires and succession: A demonstration in the Yukon River Basin of interior Alaska
Shengli Huang, Suming Jin, Devendra Dahal, Xuexia Chen, Claudia Young, Heping Liu, Shuguang Liu
2013, ISPRS Journal of Photogrammetry and Remote Sensing (79) 94-105
Land surface change caused by fires and succession is confounded by many site-specific factors and requires further study. The objective of this study was to reveal the spatially explicit land surface change by minimizing the confounding factors of weather variability, seasonal offset, topography, land cover, and drainage. In a pilot...
The role of farfield tectonic stress in oceanic intraplate deformation, Gulf of Alaska
Robert S. Reece, Sean P. S. Gulick, Gail L. Christesen, Brian K. Horton, Harm J. VanAvendonk, Ginger Barth
2013, Journal of Geophysical Research B: Solid Earth (118) 1862-1872
An integration of geophysical data from the Pacific Plate reveals plate bending anomalies, massive intraplate shearing and deformation, and a lack of oceanic crust magnetic lineaments in different regions across the Gulf of Alaska. We argue that farfield stress from the Yakutat Terrane collision with North America is the major...
A novel approach to surveying sturgeon using side-scan sonar and occupancy modeling
H. Jared Flowers, Joseph E. Hightower
2013, Marine and Coastal Fisheries: Dynamics, Management, and Ecosystem Science (5) 211-223
Technological advances represent opportunities to enhance and supplement traditional fisheries sampling approaches. One example with growing importance for fisheries research is hydroacoustic technologies such as side-scan sonar. Advantages of side-scan sonar over traditional techniques include the ability to sample large areas efficiently and the potential to survey fish without physical...

Matthew P. Zeigler, Andrew S. Todd, Colleen A. Caldwell
2013, Open-File Report 2013-1051
This study characterized the thermal regime in a number of Colorado and New Mexico streams that contain populations of Rio Grande cutthroat trout (Oncorhynchus clarkii virginalis) and had no previous record of continual temperature records. When compared to Colorado’s water temperature criteria (Cold Tier 1), a portion of these populations...
Community-based water-quality monitoring in the Yukon River Basin and the Kuskokwim Watershed
Nicole M. Herman-Mercer
2013, Witness the Arctic (2)
The unique partnership between the USGS and the YRITWC provides mutual benefits by fostering outreach efforts that have been essential for community empowerment and by generating scientific data for prohibitively large and remote regions that would be challenging for USGS scientists to sample as robustly alone. The addition of a...

Differential expression profiles of microRNA in the little brown bat (Myotis lucifugus) associated with white nose syndrome affected and unaffected individuals
D.D. Iwanowicz, L. R. Iwanowicz, N.P. Hitt, T.L. King
2013, Open-File Report 2013-1099
First documented in New York State in 2006, white nose syndrome (WNS) quickly became the leading cause of mortality in hibernating bat species in the United States. WNS is caused by a psychrophilic fungus, Geomyces destructans. Clinical signs of this pathogen are expressed as a dusty white fungus predominately around...

In 2013, the U.S. Geological Survey assessed the technically recoverable oil and gas resources of the Bakken and Three Forks Formations of the U.S. portion of the Williston Basin. The Bakken and Three Forks Formations were assessed as continuous and hypothetical conventional oil accumulations using a methodology similar to that...
Simulation of groundwater flow, effects of artificial recharge, and storage volume changes in the Equus Beds aquifer near the city of Wichita, Kansas well field, 1935–2008
Brian P. Kelly, Linda L. Pickett, Cristi V. Hansen, Andrew C. Ziegler
2013, Scientific Investigations Report 2013-5042
The Equus Beds aquifer is a primary water-supply source for Wichita, Kansas and the surrounding area because of shallow depth to water, large saturated thickness, and generally good water quality. Substantial water-level declines in the Equus Beds aquifer have resulted from pumping groundwater for agricultural and municipal needs, as well...

David R. Shelly, Seth C. Moran, Weston A. Thelen
2013, Geophysical Research Letters (40) 1506-1512
A vigorous swarm of over 1000 small, shallow earthquakes occurred 20–22 September 2009 beneath Mount Rainier, Washington, including the largest number of events ever recorded in a single day at Rainier since seismic stations were installed on the edifice in 1989. Many events were only clearly recorded on one or...

2013, Scientific Investigations Report 2013-5022
The U.S. Geological Survey is studying approaches to characterize the thermal regulation of water and the dynamics of cold water refugia. High temperatures have physiological impacts on anadromous fish species. Factors affecting the presence, variability, and quality of thermal refugia are known, such as riverine and watershed processes, hyporheic flows,...
Mount St. Helens, 1980 to now—what’s going on?
Daniel Dzurisin, Carolyn L. Driedger, Lisa M. Faust
2013, Fact Sheet 2013-3014, version 1.1
Mount St. Helens seized the world’s attention in 1980 when the largest historical landslide on Earth and a powerful explosive eruption reshaped the volcano, created its distinctive crater, and dramatically modified the surrounding landscape. An enormous lava dome grew episodically in the crater until 1986, when the volcano became relatively...

William S. Vernieu, Craig R. Anderson
2013, Open-File Report 2013-1066
Water releases from Glen Canyon Dam, Arizona, are the primary determinant of streamflow, sediment transport, water quality, and aquatic and riparian habitat availability in the Colorado River downstream of the dam in Grand Canyon. The presence and operation of the dam have transformed the seasonally warm Colorado River into a...
