2003, Hydrogeology Journal (11) 1-2
Hydrogeology Journal appeared in six issues containing a total of 674 pages and 47 major articles, including 22 Papers and 24 Reports, as well as Technical Notes and Book Reviews. The final issue of 2002 also contained the annual volume index. Hydrogeology Journal (HJ) is an...
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...
Preliminary soil-slip susceptibility maps, southwestern California
Douglas M. Morton, Rachel M. Alvarez, Russell H. Campbell, Kelly R. Bovard, D. T. Brown, K. M. Corriea, J. N. Lesser
2003, Open-File Report 2003-17
This group of maps shows relative susceptibility of hill slopes to the initiation sites of rainfall-triggered soil slip-debris flows in southwestern California. As such, the maps offer a partial answer to one part of the three parts necessary to predict the soil-slip/debris-flow process. A complete prediction of the process would...
Geologic map of MTM -45252 and-45257 quadrangles, Reull Vallis region of Mars
Scott C. Mest, David A. Crown
2003, IMAP 2763
Mars Transverse Mercator (MTM) quadrangles -45252 and -45257 (latitude 42.5° S. to 47.5°S., longitude 250° W. to 260° W.) cover a portion of the highlands of Promethei Terra east of Hellas basin. The map area consists of heavily cratered ancient highland materials having moderate to high relief, isolated knobs and...
Response to comment on "Pharmaceuticals, hormones, and other organic wastewater contaminants in U.S. streams, 1999-2000: A national reconnaissance"
Dana W. Kolpin, Edward T. Furlong, Michael T. Meyer, E. Michael Thurman, Steven D. Zaugg, Larry B. Barber, Herbert T. Buxton
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
R. Fujii, B.A. Bergamaschi, N. K. Ganju, J.A. Fleck, K.R. Burow-Fogg, D. Schoellhamer, S. J. Deverel
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...
Antarctic Climate Evolution (ACE) Research Initiative
F. Florindo, R. B. Dunbar, M Siegert, R. DeConto, P. J. Barrett, Alan K. Cooper, C. Escutia, T.R. Janecek, R.D. Larter, T.R. Naish, R.D. Powell
2003, Terra Antarctica (9) 127-132
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
Carol A. Finn, Sridhar Anandakrishnan, John W. Goodge, Kurt S. Panter, Christine Siddoway, Terry Wilson
2003, Eos Science News (84) 4-4
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...
Movements by juvenile and immature Steller's Sea Eagles Haliaeetus pelagicus tracked by satellite
M.J. McGrady, M. Ueta, E.R. Potapov, I. Utekhina, V. Marterov, A. Ladyguine, V. Zykov, J. Cibor, Mark R. Fuller, J.K. Seegar
2003, Ibis (145) 318-328
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
Jill A. Shaffer, Lawrence D. Igl, Frederick Vanhove
2003, Prairie Naturalist (35) 81-94
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...
