The hydrogeology and water quality of the Snake River alluvial aquifer at the Jackson Hole Airport in northwest Wyoming was studied by the U.S. Geological Survey, in cooperation with the Jackson Hole Airport Board, during water years 2011 and 2012 as part of a followup to a previous baseline study...
Fluvial rainbow trout contribute to the colonization of steelhead (Oncorhynchus mykiss) in a small stream
Dana E. Weigel, Patrick J. Connolly, Madison S. Powell
2013, Environmental Biology of Fishes (97) 1149-1159
Life history polymorphisms provide ecological and genetic diversity important to the long term persistence of species responding to stochastic environments. Oncorhynchus mykiss have complex and overlapping life history strategies that are also sympatric with hatchery populations. Passive integrated transponder (PIT) tags and parentage analysis were used to identify the life...
The effect of sampling rate and anti-aliasing filters on high-frequency response spectra
David M. Boore, Christine Goulet
2013, Bulletin of Earthquake Engineering (12) 203-216
The most commonly used intensity measure in ground-motion prediction equations is the pseudo-absolute response spectral acceleration (PSA), for response periods from 0.01 to 10 s (or frequencies from 0.1 to 100 Hz). PSAs are often derived from recorded ground motions, and these motions are usually filtered to remove high and...

We provide a chronology for...
Using age of colonizing douglas-fir for the dating of young geomorphic surfaces: a case study
Thomas C. Pierson
2013, Book chapter, Dating torrential processes on fans and cones
Dating of many types of young (<500 year), dynamic, geomorphic landforms (e.g. mass-movement erosional tracks and deposits, alluvial terraces, flood plains, etc.) for purposes of hazard assessment and mitigation commonly requires greater dating precision than is available through radiocarbon dating or other methods. Ages of trees growing on landform surfaces...

2013, Journal of Geophysical Research (118) 5428-5441
High-resolution sparker and crustal-scale air gun seismic reflection data, coupled with repeat bathymetric surveys, document a region of repeated coseismic uplift on the portion of the Alaska subduction zone that ruptured in 1964. This area defines the western limit of Prince William Sound. Differencing of vintage and modern bathymetric surveys...
Introduction in New perspectives on Rio Grande rift basins: from tectonics to groundwater
Mark R. Hudson, V. J. S. Grauch
2013, Book chapter, New perspectives on Rio Grande rift basins: from tectonics to groundwater
Basins of the Rio Grande rift have long been studied both for their record of rift development and for their potential as host of natural resources. Early workers described the basin geomorphology and the character of infilling sediments (e.g. Siebenthal, 1910; Bryan, 1938; Speigel and Baldwin, 1963), and subsequent...

2013, Parasitology (140) 1741-1750
Next-generation 454 sequencing techniques were used to re-examine diversity of mitochondrial cytochrome b lineages of avian malaria (Plasmodium relictum) in Hawaii. We document a minimum of 23 variant lineages of the parasite based on single nucleotide transitional changes, in addition to the previously reported single lineage (GRW4). A new, publicly...
Compilation, quality control, analysis, and summary of discrete suspended-sediment and ancillary data in the United States, 1901-2010
Casey J. Lee, G. Douglas Glysson
2013, Data Series 776
Human-induced and natural changes to the transport of sediment and sediment-associated constituents can degrade aquatic ecosystems and limit human uses of streams and rivers. The lack of a dedicated, easily accessible, quality-controlled database of sediment and ancillary data has made it difficult to identify sediment-related water-quality impairments and has limited...

Contribution of calcium oxalate to soil-exchangeable calcium
Jenny M. Dauer, Steven S. Perakis
2013, Soil Science (178) 671-678
Acid deposition and repeated biomass harvest have decreased soil calcium (Ca) availability in many temperate forests worldwide, yet existing methods for assessing available soil Ca do not fully characterize soil Ca forms. To account for discrepancies in ecosystem Ca budgets, it has been hypothesized that the highly insoluble biomineral Ca...
