Velocity ratio and its application to predicting velocities
Myung W. Lee
2003, Bulletin 2197
The velocity ratio of water-saturated sediment derived from the Biot-Gassmann theory depends mainly on the Biot coefficient?a property of dry rock?for consolidated sediments with porosity less than the critical porosity. With this theory, the shear moduli of dry sediments are the same as the shear moduli of water-saturated sediments. Because the...
Geologic map of the Hogback Mountain quadrangle, Lewis and Clark and Meagher Counties, Montana
Mitchell W. Reynolds
2003, IMAP 2773
The geologic map of the Hogback Mountain quadrangle, scale 1:24,000, was made as part of the Montana Investigations Project to provide new information on the stratigraphy, structure, and geologic history of an area in the geologically complex southern part of the Montana disturbed belt. In the Hogback Mountain area,...
Correlation of the Klamath Mountains and Sierra Nevada
William P. Irwin
2003, Open-File Report 2002-490
This report graphically portrays the broadly parallel tectonic development of the Klamath Mountains and Sierra Nevada from early Paleozoic to Early Cretaceous time. It is dedicated to J.S. Diller of the U.S. Geological Survey who, during his pioneer field studies a century ago, recognized significant similarities between these two important...
Geochemistry of Permian rocks from the margins of the Phosphoria Basin: Lakeridge core, western Wyoming
Robert B. Perkins, Brandie McIntyre, James R. Hein, David Z. Piper
2003, Open-File Report 2003-21
The Permian Phosphoria Formation and interbedded units of the Park City Formation and Shedhorn Sandstone in western Wyoming represent deposition along a carbonate ramp at the eastern margin of the Phosphoria Basin, with portions of the Phosphoria units reflecting periods of upwelling and widespread phosphogenesis. Thickness-weighted slab-samples of these units...

Response to comment on "Pharmaceuticals, hormones, and other organic wastewater contaminants in U.S. streams, 1999-2000: A national reconnaissance"

2003, Environmental Science & Technology (37) 1054-1054
Till (1) raised concerns that several aspects of how we handled the data in our study (2) may have caused unintended bias. First, Till (1) considers the “median detectable concentrations” listed in Table 1 (2) to be misleading because “higher median concentrations than is actually the case” were suggested. We...
Tidal wetland fluxes of dissolved organic carbon and sediment at Browns Island, California: initial evaluation
N. K. Ganju, B. Bergamaschi, D. H. Schoellhamer
2003, Conference Paper, Proceedings of the 2003 CALFED science conference
Carbon and sediment fluxes from tidal wetlands are of increasing concern in the Sacramento-San Joaquin River Delta (Delta), because of drinking water issues and habitat restoration efforts. Certain forms of dissolved organic carbon (DOC) react with disinfecting chemicals used to treat drinking water, to form disinfection byproducts (DBPs), some of...

Preliminary assessment of DOC and THM precursor loads from a freshwater restored wetland, an agricultural field, and a tidal wetland in the Sacramento-San Joaquin River Delta

2003, Conference Paper, Proceedings of the 2003 CALFED science conference
Water exported from the Sacramento-San Joaquin River Delta supplies drinking water to more than 22 million people in California. At certain times of the year, Delta waters contain relatively high concentrations of dissolved organic carbon (DOC) and bromide. During these times, chlorination of Delta water for drinking water disinfection will...

The Antarctic Climate Evolution (ACE) project is a new international research initiative to study the climate and glacial history of Antarctica by linking climate and ice sheet modeling studies with geophysical surveys and geological studies on and around the Antarctic continent (Fig. 1). The rationale for the ACE programme, outlined...
Potential of airborne geophysical capabilities discussed

Antarctica is a key element in Earth's geodynamic and climatic systems. Nevertheless, on the eve of the 50th anniversary of the International Geophysical Year, we lack fundamental geologic and geophysical data from the deep interior of this vast continent. Meager exposures record the 3500-million-year history of a continent that participated...
Evidence for orbitally controlled size variations of the East Antarctic Ice Sheet during the late Miocene
J. Grutzner, M. Rebesco, Alan K. Cooper, C.F. Forsberg, K.A. Kryc, G. Wefer
2003, Geology (31) 777-780
Ocean Drilling Program Site 1165 penetrated drift sediments on the East Antarctic continental rise and recovered sediments from a low-energy depositional environment. The sediments are characterized by prominent alternations between a green to greenish-gray diatom-bearing hemipelagic facies and gray to dark gray hemiturbiditic facies. Our investigation of an upper Miocene...

Twenty-four juvenile Steller's Sea Eagles Haliaeetus pelagicus were tracked via satellite from natal areas in Magadan, Kabarovsk, Amur, Sakhalin and Kamchatka. Nestling dispersal occurred between 9 September and 6 December (n = 24), mostly 14 September-21 October, and did not differ among regions or years. Most eagles made stopovers of...
A summary of the San Francisco tidal wetlands restoration series
Larry R. Brown
2003, San Francisco Estuary and Watershed Science (1)
The four topical articles of the Tidal Wetlands Restoration Series summarized and synthesized much of what is known about tidal wetlands and tidal wetland restoration in the San Francisco Estuary (hereafter “Estuary”). Despite a substantial amount of available information, major uncertainties remain. A major uncertainty with regard to fishes is...
Guidelines for finding nests of passerine birds in tallgrass prairie
Maiken Winter, Shawn E. Hawks, Jill A. Shaffer, Douglas H. Johnson
2003, Prairie Naturalist (35) 197-211
The productivity of birds is one of the most critical components of their natural history affected by habitat quality. Birds might occur at high densities in a given habitat patch but have low nesting success. Such "population sinks" would not be detected if observers relied solely on estimates of bird...
Potential for increased mercury accumulation in the estuary food web
Jay A. Davis, Donald Yee, Joshua N. Collins, Steven E. Schwarzbach, Samuel N. Luoma
2003, San Francisco Estuary and Watershed Science (1)
Present concentrations of mercury in large portions of San Francisco Bay (Bay), the Sacramento-San Joaquin Delta (Delta), and the Sacramento and San Joaquin rivers are high enough to warrant concern for the health of humans and wildlife. Large scale tidal wetland restoration is currently under consideration as a means of...
Historical and recent records and first nest records of Henslow's sparrow in North Dakota

The northwestern limit of the Henslow's sparrow (Ammodramus henslowii) breeding distribution occurs in southern Minnesota and central Wisconsin. In North Dakota, observations of Henslow's sparrows are reported infrequently, and there are no published nest records in the state. Herein, we summarize and review previous reports of Henslow's sparrows in North...
