Heat tracer methods
Richard W. Healy
2010, Book chapter, Estimating groundwater recharge
The flow of heat in the subsurface is closely linked to the movement of water (Ingebritsen et al., 2006). As such, heat has been used as a tracer in groundwater studies for more than 100 years (Anderson, 2005). As with chemical and isotopic tracers (Chapter 7), spatial or temporal...
Tectonic controls on nearshore sediment accumulation and submarine canyon morphology offshore La Jolla, Southern California
Nicolas Le Dantec, Leah J. Hogarth, Neal W. Driscoll, Jeffrey M. Babcock, Walter A. Barnhardt, William C. Schwab
2010, Marine Geology (268) 115-128
CHIRP seismic and swath bathymetry data acquired offshore La Jolla, California provide an unprecedented three-dimensional view of the La Jolla and Scripps submarine canyons. Shore-parallel patterns of tectonic deformation appear to control nearshore sediment thickness and distribution around the canyons. These shore-parallel patterns allow the impact of local tectonic deformation...
Aquatic community responses to salmon carcass analog and wood bundle additions in restored floodplain habitats in an Alaskan stream
Aaron E. Martin, Mark S. Wipfli, Robert E. Spangler
2010, Transactions of the American Fisheries Society (139) 1828-1845
Land use activities often directly and indirectly limit the capacity of freshwater habitats to produce fish. Consequently, habitat creation and enhancement actions are often undertaken to increase the quantity and quality of resources available to aquatic communities within these impaired systems, with the intent to increase fish production. The objectives...
Modeling methods
Richard W. Healy
2010, Book chapter, Estimating groundwater recharge
Simulation models are widely used in all types of hydrologic studies, and many of these models can be used to estimate recharge. Models can provide important insight into the functioning of hydrologic systems by identifying factors that influence recharge. The predictive capability of models can be used to evaluate how...

Jennifer C. McIntosh, Peter D. Warwick, Anna M. Martini, Stephen G. Osborn
2010, GSA Bulletin (122) 1248-1264
Thirty-six formation waters, gas, and microbial samples were collected and analyzed from natural gas and oil wells producing from the Paleocene to Eocene Wilcox Group coal beds and adjacent sandstones in north-central Louisiana, USA, to investigate the role hydrology plays on the generation and distribution of microbial methane. Major ion...
Summary of groundwater-recharge estimates for Pennsylvania
Stuart O. Reese, Dennis W. Risser
2010, Water Resource Report 70
Groundwater recharge is water that infiltrates through the subsurface to the zone of saturation beneath the water table. Because recharge is a difficult parameter to quantify, it is typically estimated from measurements of other parameters like streamflow and precipitation. This report provides a general overview of processes affecting recharge in...

Batrachochytrium dendrobatidis is a fungal pathogen that is receiving attention around the world for its role in amphibian declines. Study of its occurrence patterns is hampered by false negatives: the failure to detect the pathogen when it is present. Occupancy models are a useful but currently underutilized tool for analyzing...
On the irrigation requirements of cottonwood (Populus fremontii and Populus deltoides var. wislizenii) and willow (Salix gooddingii) grown in a desert environment
S. Hartwell, K. Morino, P.L. Nagler, E. P. Glenn
2010, Journal of Arid Environments (74) 667-674
Native tree plots have been established in river irrigation districts in the western U.S. to provide habitat for threatened and endangered birds. Information is needed on the effective irrigation requirements of the target species. Cottonwood (Populus spp.) and willow (Salix gooddingii) trees were grown for seven years in an outdoor...

J.W. Nichols, R.S. Bennett, R. Rossmann, John B. French, K.G. Sappington
2010, Environmental Toxicology and Chemistry (29) 1854-1867
A physiologically based toxicokinetic (PBTK) model was developed to describe the uptake, distribution, and elimination of methylmercury (CH 3Hg) in female American kestrels. The model consists of six tissue compartments corresponding to the brain, liver, kidney, gut, red blood cells, and remaining carcass. Additional compartments describe the elimination of CH3Hg...

During April 2004, 40 sick and dead southern sea otters (Enhydra lutris nereis) were recovered over 18 km of coastline near Morro Bay, California. This event represented the single largest monthly spike in mortality ever recorded during 30 years of southern sea otter stranding data collection. Because of the point-source...

T. Hughes, P. Irwin, E. Hofmeister, S.M. Paskewitz
2010, Journal of the American Mosquito Control Association (26) 24-31
The occurrence of multiple pathogens in mosquitoes and birds could affect the dynamics of disease transmission. We collected adult Culex pipiens and Cx. restuans (Cx. pipiens/restuans hereafter) from sites in Wisconsin and tested them for West Nile virus (WNV) and for avian malaria (Plasmodium). Gravid Cx. pipiens/restuans were tested for...

A.T. Pearse, Gary L. Krapu, D.A. Brandt, P.J. Kinzel
2010, Journal of Wildlife Management (74) 479-488
The central Platte River valley (CPRV) in Nebraska, USA, is a key spring-staging area for approximately 80 of the midcontinent population of sandhill cranes (Grus canadensis; hereafter cranes). Evidence that staging cranes acquired less lipid reserves during the 1990s compared to the late 1970s and increases in use of the...
Dacite petrogenesis on mid-ocean ridges: Evidence for oceanic crustal melting and assimilation
V.D. Wanless, M.R. Perfit, W.I. Ridley, E. Klein
2010, Journal of Petrology (51) 2377-2410
Whereas the majority of eruptions at oceanic spreading centers produce lavas with relatively homogeneous mid-ocean ridge basalt (MORB) compositions, the formation of tholeiitic andesites and dacites at mid-ocean ridges (MORs) is a petrological enigma. Eruptions of MOR high-silica lavas are typically associated with ridge discontinuities and have produced regionally significant...

Characterization of pyroclastic deposits and pre-eruptive soils following the 2008 eruption of Kasatochi Island Volcano, Alaska
B. Wang, G. Michaelson, C.-L. Ping, G. Plumlee, P. Hageman
2010, Arctic, Antarctic, and Alpine Research (42) 276-284
The 78 August 2008 eruption of Kasatochi Island volcano blanketed the island in newly generated pyroclastic deposits and deposited ash into the ocean and onto nearby islands. Concentrations of water soluble Fe, Cu, and Zn determined from a 1:20 deionized water leachate of the ash were sufficient to provide short-term...
