The removal of two dams on the Elwha River will introduce massive volumes of sediment to the river, and this increase in sediment supply in the river will likely modify the shapes and forms of the river and coastal landscape downstream of the dams. This chapter provides the geologic and...
Aeromagnetic anomalies over faulted strata
V. J. S. Grauch, Mark R. Hudson
2011, The Leading Edge (30) 1242-1252
High-resolution aeromagnetic surveys are now an industry standard and they commonly detect anomalies that are attributed to faults within sedimentary basins. However, detailed studies identifying geologic sources of magnetic anomalies in sedimentary environments are rare in the literature. Opportunities to study these sources have come from well-exposed sedimentary basins of...

Decomposition of heterogeneous organic matterand its long-term stabilization in soils
Carlos A. Sierra, Mark E. Harmon, Steven S. Perakis
2011, Ecological Monographs (81) 619-634
Soil organic matter is a complex mixture of material with heterogeneous biological, physical, and chemical properties. Decomposition models represent this heterogeneity either as a set of discrete pools with different residence times or as a continuum of qualities. It is unclear though, whether these two different approaches yield comparable predictions...
Regional correlations of VS30 averaged over depths less than and greater than 30 meters
David M. Boore, Eric M. Thompson, Heloise Cadet
2011, Bulletin of the Seismological Society of America (101) 3046-3059
Using velocity profiles from sites in Japan, California, Turkey, and Europe, we find that the time-averaged shear-wave velocity to 30 m (VS30), used as a proxy for site amplification in recent ground-motion prediction equations (GMPEs) and building codes, is strongly correlated with average velocities to depths less than 30 m...

A trans-dimensional Bayesian Markov chain Monte Carlo algorithm for model assessment using frequency-domain electromagnetic data
Burke J. Minsley
2011, Geophysical Journal International (187) 252-272
A meaningful interpretation of geophysical measurements requires an assessment of the space of models that are consistent with the data, rather than just a single, ‘best’ model which does not convey information about parameter uncertainty. For this purpose, a trans-dimensional Bayesian Markov chain Monte Carlo (MCMC) algorithm is developed for...

2011, Earthquake Spectra (27) 1219-1235
The ground-motion prediction equations (GMPEs) developed as part of the Next Generation Attenuation of Ground Motions (NGA-West) project in 2008 are becoming widely used in seismic hazard analyses. However, these new models are considerably more complicated than previous GMPEs, and they require several more input parameters. When employing the NGA...
Influence of dreissenid mussels on catchability of benthic fishes in bottom trawls
Patrick M. Kocovsky, Martin A. Stapanian
2011, Transactions of the American Fisheries Society (140) 1565-1573
Inferring trends in true abundance of fish populations from catch per unit effort data requires either the knowledge of capture probability or the assumption that it is constant, both of which are unlikely contingencies. We developed and validated an index of catchability (a proxy measure for capture probability) from a...
Estimating groundwater recharge
David A. Stonestrom
2011, Eos, Transactions, American Geophysical Union (92) 269-269
Groundwater recharge is the entry of fresh water into the saturated portion of the subsurface part of the hydrologic cycle, the modifier “saturated” indicating that the pressure of the pore water is greater than atmospheric. Briefly stated, recharge is downward flux across the water table. The term “groundwater recharge” can...
Seasonal productivity in a population of migratory songbirds: why nest data are not enough
Henry M. Streby, David E. Andersen
2011, Ecosphere (2) 1-15
Population models for many animals are limited by a lack of information regarding juvenile survival. In particular, studies of songbird reproductive output typically terminate with the success or failure of nests, despite the fact that adults spend the rest of the reproductive season rearing dependent fledglings. Unless fledgling survival does...
