To understand the effects of increased sediment supply from dam removal on marine habitats around the Elwha River delta, a basic understanding of the region’s coastal processes is necessary. This chapter provides a summary of the physical setting of the coast near the Elwha River delta, for the purpose of...
Liquefaction probability curves for surficial geologic deposits
Thomas L. Holzer, Thomas E. Noce, Michael J. Bennett
2011, Environmental & Engineering Geoscience (17) 1-21
Liquefaction probability curves that predict the probability of surface manifestations of earthquake-induced liquefaction are developed for 14 different types of surficial geologic units. The units consist of alluvial fan, beach ridge, river delta topset and foreset beds, eolian dune, point bar, flood basin, natural river and alluvial fan levees, abandoned...

2011, Scientific Investigations Report 2011-5120-7
The removal of two long-standing dams on the Elwha River in Washington State will initiate a suite of biological and physical changes to the estuary at the river mouth. Estuaries represent a transition between freshwater and saltwater, have unique assemblages of plants and animals, and are a critical habitat for...
Seasonally dynamic diel vertical migrations of Mysis diluviana, coregonine fishes, and siscowet lake trout in the pelagia of western Lake Superior
Tyler D. Ahrenstorff, Thomas R. Hrabik, Jason D. Stockwell, Daniel L. Yule, Greg G. Sass
2011, Transactions of the American Fisheries Society (140) 1504-1520
Diel vertical migrations are common among many aquatic species and are often associated with changing light levels. The underlying mechanisms are generally attributed to optimizing foraging efficiency or growth rates and avoiding predation risk (μ). The objectives of this study were to (1) assess seasonal and interannual changes in vertical...

2011, Scientific Investigations Report 2011-5120-2
During and after the planned incremental removal of two large, century-old concrete dams between 2011 and 2014, the sediment-transport regime in the lower Elwha River of western Washington will initially spike above background levels and then return to pre-dam conditions some years after complete dam removal. Measurements indicate the upper...

Ellen Raabe, David Stonehouse, Kristin Ebersol, Kathryn Holland, Lisa Robbins
2011, Professional Geologist (48) 42-49
Along the Gulf Coast of Florida north of Tampa Bay lies a region characterized by an open marsh coast, low topographic gradient, water-bearing limestone, and scattered springs. The Floridan aquifer system is at or near land surface in this region, discharging water at a consistent 70-72°F. The thermal contrast between...
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...

Guidance manual for forensic analysis of perchlorate in groundwater using chlorine and oxygen isotopic analyses
2011, Report
Increased health concerns about perchlorate (ClO4-) during the past decade and subsequent regulatory considerations have generated appreciable interest in source identification. The key objective of the isotopic techniques described in this guidance manual is to provide evidence concerning the origin of ClO4- in soils and groundwater and, more specifically, whether...

2011, Conference Paper, The proceedings of the coastal sediments 2011
The nearshore bathymetric evolution of a high-energy beach at the mouth of San Francisco Bay, California (USA), was tracked before, during, and after the powerful El Niño winter of 2009-10 to quantify alongshore bar formation and migration as well as the magnitude and alongshore variability of cross-shore transport. The observed...

Christopher J. Hein, Duncan M. FitzGerald, Emily A. Carruthers, Byron D. Stone, Allen M. Gontz
2011, Conference Paper, The Proceedings of the Coastal Sediments 2011
Barrier islands develop through a variety of processes, including spit accretion, barrier elongation, and inlet filling. New geophysical and sedimentological data provide a means of documenting the presence of a paleoinlet within a barrier lithosome in the western Gulf of Maine, illuminating the process of backbarrier infilling and its effect...

Methane hydrate-bearing seeps as a source of aged dissolved organic carbon to the oceans
John W. Pohlman, William F. Waite, James E. Bauer, Christopher L. Osburn, N. Ross Chapman
2011, Nature Geoscience (4) 37-41
Marine sediments contain about 500–10,000 Gt of methane carbon1, 2, 3, primarily in gas hydrate. This reservoir is comparable in size to the amount of organic carbon in land biota, terrestrial soils, the atmosphere and sea water combined1, 4, but it releases relatively little methane to the ocean and atmosphere5. Sedimentary...

Water and heat transport in boreal soils: Implications for soil response to climate change
Zhaosheng Fan, Jennifer W. Harden, G.C. Winston, Jonathan A. O’Donnell, Jason C. Neff, Tingjun Zhang, Hugo Veldhuis, C.I. Czimczik
2011, Science of the Total Environment (409) 1836-1842
Soil water content strongly affects permafrost dynamics by changing the soil thermal properties. However, the movement of liquid water, which plays an important role in the heat transport of temperate soils, has been under-represented in boreal studies. Two different heat transport models with and without convective heat transport were compared...
