USGS Reference Materials Program: Serving the Needs of the Global Analytical Community
Ruth E. Wolf, Stephen A. Wilson
2007, Fact Sheet 2007-3056
Every year in the United States, millions of measurements are made on the chemical composition of items that affect us on a daily basis. The accuracy of these measurements is routinely determined by the analysis of appropriate reference materials. In the field of earth science, reference materials are particularly important...
Seismic detection and analysis of icequakes at Columbia Glacier, Alaska
Shad O’Neel, Hans P. Marshall, Daniel E. McNamara, William Tad Pfeffer
2007, Journal of Geophysical Research (112)
Contributions to sea level rise from rapidly retreating marine-terminating glaciers are large and increasing. Strong increases in iceberg calving occur during retreat, which allows mass transfer to the ocean at a much higher rate than possible through surface melt alone. To study this process, we deployed an 11-sensor passive seismic...
Endangered light-footed clapper rail affects parasite community structure in coastal wetlands
Kathleen L. Whitney, Ryan F. Hechinger, Armand M. Kuris, Kevin D. Lafferty
2007, Ecological Applications (17) 1694-1702
An extinction necessarily affects community members that have obligate relationships with the extinct species. Indirect or cascading effects can lead to even broader changes at the community or ecosystem level. However, it is not clear whether generalist parasites should be affected by the extinction of one of their hosts. We...

Determining the pattern of cementum annuli and relationship to reproduction in male sea otters
Josh Proper, Vanessa R. von Biela, Jennifer M. Burns
2007, Ethnicity and Disease (17) S545-S547
Since the early 1990s, the southwestern Alaskan sea otter (Enhydra lutris) population has declined dramatically and the cause has yet to be determined. Population trajectories of large mammals are determined by three factors: survival rate, reproduction rate, and age of first reproduction (AFR). Of these three, AFR should respond first...

Lava flow hazard assessment, as of August 2007, for Kīlauea east rift zone eruptions, Hawai‘i Island
Jim Kauahikaua
2007, Open-File Report 2007-1264
The most recent episode in the ongoing Pu'u 'O'o-Kupaianaha eruption of Kilauea Volcano is currently producing lava flows north of the east rift zone. Although they pose no immediate threat to communities, changes in flow behavior could conceivably cause future flows to advance downrift and impact communities thus far unaffected....

2007, Conference Paper, Proceedings, XXIII International Cartographic Conference
The Mars Reconnaissance Orbiter (MRO) arrived at Mars on 10 March 2006 and began its primary science phase in November. The High Resolution Imaging Science Experiment (HiRISE) on MRO is the largest, most complex camera ever flown to another planet. Plans call for this scanner to image roughly 1% of...
Cartography for lunar exploration: Current status and planned missions
Randolph L. Kirk, Brent A. Archinal, Lisa R. Gaddis, Mark R. Rosiek
2007, Conference Paper, Proceedings: XXIII International Cartographic Conference
The initial spacecraft exploration of the Moon in the 1960s–70s yielded extensive data, primarily in the form of film and television images, that were used to produce a large number of hardcopy maps by conventional techniques. A second era of exploration, beginning in the early 1990s, has produced digital data...
Escherichia coli Concentrations in the Mill Creek Watershed, Cleveland, Ohio, 2001-2004
Amie M. G. Brady
2007, Open-File Report 2007-1171
Mill Creek in Cleveland, Ohio, receives discharges from combined-sewer overflows (CSOs) and other sanitary-sewage inputs. These discharges affect the water quality of the creek and that of its receiving stream, the Cuyahoga River. In an effort to mitigate this problem, the Northeast Ohio Regional Sewer District implemented a project to...
Methods for estimating magnitude and frequency of peak flows for natural streams in Utah
Terry A. Kenney, Chris D. Wilkowske, Shane J. Wright
2007, Scientific Investigations Report 2007-5158
Estimates of the magnitude and frequency of peak streamflows is critical for the safe and cost-effective design of hydraulic structures and stream crossings, and accurate delineation of flood plains. Engineers, planners, resource managers, and scientists need accurate estimates of peak-flow return frequencies for locations on streams with and without streamflow-gaging...
