Updating the USGS seismic hazard maps for Alaska
Charles Mueller, Richard W. Briggs, Robert L. Wesson, Mark D. Petersen
2015, Quaternary Science Reviews (113) 39-47
The U.S. Geological Survey makes probabilistic seismic hazard maps and engineering design maps for building codes, emergency planning, risk management, and many other applications. The methodology considers all known earthquake sources with their associated magnitude and rate distributions. Specific faults can be modeled if slip-rate or recurrence information is available....
Suspended-sediment transport and storage: A demonstration of acoustic methods in the evaluation of reservoir management strategies for a small water-supply reservoir in western Colorado
Cory A. Williams, Rodney J. Richards, Kent L. Collins
2015, Conference Paper
The U.S. Bureau of Reclamation (USBR) and local stakeholder groups are evaluating reservoir-management strategies within Paonia Reservoir. This small reservoir fills to capacity each spring and requires approximately half of the snowmelt-runoff volume from its sediment-laden source waters, Muddy Creek. The U.S. Geological Survey is currently conducting high-resolution (15-minute data-recording...
Baseline and premining geochemical characterization of mined sites
D. Kirk Nordstrom
2015, Applied Geochemistry (57) 17-34
A rational goal for environmental restoration of new, active, or inactive mine sites would be ‘natural background’ or the environmental conditions that existed before any mining activities or other related anthropogenic activities. In a strictly technical sense, there is no such thing as natural background (or entirely non-anthropogenic) existing today...
Sedimentology of SPICE (Steptoean positive carbon isotope excursion): A high-resolution trace fossil and microfabric analysis of the middle to late Cambrian Alum Shale Formation, southern Sweden
Sven Egenhoff, Neil Fishman, Per Ahlberg, Jorg Maletz, Allison Jackson, Ketki Kolte, Heather A. Lowers, James Mackie, Warren Newby, Matthew Petrowsky
2015, Book chapter, Paying Attention to Mudrocks: Priceless!
The Cambrian Alum Shale Formation in the Andrarum-3 core from Scania, southern Sweden, consists of black siliciclastic mudstone with minor carbonate intercalations. Four facies comprise three siliciclastic mudstones and one fine-grained carbonate. The facies reflect deposition along a transect from deep ramp to basin on a Cambrian shelf. The three...
Risk management of El Chichón and Tacaná Volcanoes: Lessons learned from past volcanic crises: Chapter 8
Servando De la Cruz-Reyna, Robert I. Tilling
2015, Book chapter, Active Volcanoes of Chiapas (Mexico): El Chichón and Tacaná
Before 1985, Mexico lacked civil-protection agencies with a mission to prevent and respond to natural and human-caused disasters; thus, the government was unprepared for the sudden eruption of El Chichón Volcano in March–April 1982, which produced the deadliest volcanic disaster in the country’s recorded history (~2,000 fatalities). With the sobering...

Nutrient attenuation in rivers and streams, Puget Sound Basin, Washington
Rich W. Sheibley, Christopher P. Konrad, Robert W. Black
2015, Scientific Investigations Report 2015-5074
Nutrients such as nitrogen and phosphorus are important for aquatic ecosystem health. Excessive amounts of nutrients, however, can make aquatic ecosystems harmful for biota because enhanced growth and decay cycles of aquatic algae can reduce dissolved oxygen in the water. In Puget Sound marine waters, low dissolved oxygen concentrations are...

Ecosystem services science, practice, and policy: Perspectives from ACES, A Community on Ecosystem Services
Carl D. Shapiro, Greg Arthaud, Frank Casey, Dianna M. Hogan
2015, Ecological Economics (115) 1-2
Ecosystem services are at a crossroad. The natural capital needed to produce them is diminishing (Millennium Ecosystem Assessment, 2005). At the same time, the science relating to their identification, production, and valuation is advancing. Examples of ecosystem services applications are abundant in the literature. In addition, the concept of ecosystem...
Sampling techniques for burbot in a western non-wadeable river
Z. B. Klein, Michael C. Quist, D.T. Rhea, A. C. Senecal
2015, Fisheries Management and Ecology (22) 213-223
Burbot, Lota lota (L.), populations are declining throughout much of their native distribution. Although numerous aspects of burbot ecology are well understood, less is known about effective sampling techniques for burbot in lotic systems. Occupancy models were used to estimate the probability of detection () for three...
Geologic and geomorphic controls on the occurrence of fens in the Oregon Cascades and implications for vulnerability and conservation
A. Aldous, Marshall W. Gannett, Mackenzie K. Keith, James E. O'Connor
2015, Wetlands (35) 757-767
Montane fens are biologically diverse peat-forming wetlands that develop at points of groundwater discharge. To protect these ecosystems, it is critical to understand their locations on the landscape and the hydrogeologic systems that support them. The upper Deschutes Basin has a groundwater flow system that supports baseflow in many rivers,...
Concentrations of metals and trace elements in aquatic biota associated with abandoned mine lands in the Whiskeytown National Recreation Area and nearby Clear Creek watershed, Shasta County, northwestern California, 2002-2003
Roger L. Hothem, Jason T. May, Jennifer K. Gibson, Brianne E. Brussee
2015, Open-File Report 2015-1077
Park management of the Whiskeytown National Recreation Area, in northwestern California, identified a critical need to determine if mercury (Hg) or other elements originating from abandoned mines within the Upper Clear Creek watershed were present at concentrations that might adversely affect aquatic biota living within the park. During 2002–03, the...

Quantifying water flow and retention in an unsaturated fracture-facial domain
John R. Nimmo, Siamak Malek-Mohammadi
2015, Book chapter, Fluid dynamics in complex fractured-porous systems
Hydrologically significant flow and storage of water occur in macropores and fractures that are only partially filled. To accommodate such processes in flow models, we propose a three-domain framework. Two of the domains correspond to water flow and water storage in a fracture-facial region, in addition to the third domain...

During the spring of 2012, the U.S. Geological Survey, in cooperation with the Arkansas Natural Resources Commission and the Arkansas Geological Survey, measured water levels in 342 wells completed in the Mississippi River Valley alluvial aquifer in eastern Arkansas. The Arkansas Natural Resources Commission measured water levels in 11 wells,...
The modern muds of Laguna Mar Chiquita (Argentina): Particle size and geochemical trends from a large saline lake in the "thick-skinned" Andean foreland
Michael M McGlue, Geoffrey S Ellis, Andrew S. Cohen
2015, GSA Special Papers (515) 1-18
Laguna Mar Chiquita (central Argentina; ~latitude 31°S, longitude 63°W) provides an outstanding opportunity to examine organic facies development and petroleum source-rock potential in a modern thick-skinned foreland basin lake. In this case study, we define profundal, paleodelta, and lake-margin depositional environments based on trends in bathymetry and lake-floor sediment particle...
Linear models for airborne-laser-scanning-based operational forest inventory with small field sample size and highly correlated LiDAR data
Virpi Junttila, Tuomo Kauranne, Andrew O. Finley, John B. Bradford
2015, IEEE Transactions on Geoscience and Remote Sensing (53) 5600-5612
Modern operational forest inventory often uses remotely sensed data that cover the whole inventory area to produce spatially explicit estimates of forest properties through statistical models. The data obtained by airborne light detection and ranging (LiDAR) correlate well with many forest inventory variables, such as the tree height, the timber...
