African and Asian dust: from desert soils to coral reefs
Virginia H. Garrison, Eugene A. Shinn, William T. Foreman, Dale W. Griffin, Charles W. Holmes, Christina A. Kellogg, Michael S. Majewski, Laurie L. Richardson, Kim B. Ritchie, Garriet W. Smith
2003, BioScience (53) 469-480
Many hypotheses have been proposed to explain the decline of coral reefs throughout the world, but none adequately accounts for the lack of recovery of reefs or the wide geographical distribution of coral diseases. The processes driving the decline remain elusive. Hundreds of millions of tons of dust transported annually...
Influence of climate on deep-water clastic sedimentation: application of a modern model, Peru-Chile Trough, to an ancient system, Ouachita Trough
N. Terence Edgar, C. Blaine Cecil
2003, Climate Controls on Stratigraphy: SEPM Special Publication (77) 185-191
Traditionally, an abrupt and massive influx of siliciclastic sediments into an area of deposition has been attributed to tectonic uplift without consideration of the influence of climate or climatic change on rates of weathering, erosion, transportation, and deposition. With few exceptions, fluvial sediment transport is minimal in both extremely arid...
A modern analogue for tectonic, eustatic, and climatic processes in cratonic basins: Gulf of Carpentaria, northern Australia
N. Terence Edgar, C. Blaine Cecil, R.E. Mattick, Patrick de Deckker, Yusuf S. Djajadihardja
2003, Climate Controls on Stratigraphy: SEPM Special Publication (77) 193-205
The Gulf of Carpentaria is a tropical, silled epicontinental sea and may be a modern analogue for ancient cratonic basins. For the purpose of this study, the Gulf of Carpentaria is compared to Pennsylvanian cratonic basins of the United States. During the Pennsylvanian, the North American continent moved from the...
Mobility of authigenic rhenium, silver, and selenium during postdepositional oxidation in marine sediments
John Crusius, John Thomson
2003, Geochimica et Cosmochimica Acta (67) 265-273
Sedimentary records of redox-sensitive trace elements hold significant potential as indicators of paleoceanographic environmental conditions. Records of Re can reveal the intensity of past reducing conditions in sediments at the time of deposition, whereas records of Ag may record the magnitude of past diatom fluxes to the seafloor. Confidence in...
Tale of two pit lakes: initial results of a three-year study of the Main Zone and Waterline pit lakes near Houston, British Columbia, Canada
John Crusius, R. Pieters, A. Leung, P. Whittle, T. Pedersen, G. Lawrence, J.J. McNee
2003, Mining Engineering (55) 25-30
Pit lakes are becoming increasingly common in North America as well as in the rest of the world. They are created as openpit mines fill passively with ground water and surface inflows on cessation of mining activity. In many instances, the water quality in these pit lakes does not meet...
Quaternary sedimentation and subsidence history of Lake Baikal, Siberia, based on seismic stratigraphy and coring
Steven M. Colman, E.B. Karabanov, C. H. Nelson III
2003, Journal of Sedimentary Research (73) 941-956
The long, continuous, high-latitude, stratigraphic record of Lake Baikal was deposited in three broad sedimentary environments, defined by high-resolution seismic-reflection and coring methods: (1) turbidite depositional systems, by far the most widespread, characterizing most of the margins and floors of the main basins of the lake, (2) large deltas of...
Complexity analysis of the change in shoreline position at Duck, NC
Christopher Barton, Jeffrey S. Dismukes, R.A. Morton
2003, Conference Paper, Coastal sediments '03: "crossing disciplinary boundaries": the Fifth International Symposium on Coastal Engineering and Science of Coastal Sediment Processes: proceedings: May 18-23, 2003, Sheraton Sand Key Resort, Clearwater Beach, Florida, USA

Links between erosional hotspots and alongshore sediment transport
Andrew Ashton, Jeffrey H. List, A. Brad Murray, Amy S. Farris
2003, Conference Paper, Coastal sediments '03: "crossing disciplinary boundaries": the Fifth International Symposium on Coastal Engineering and Science of Coastal Sediment Processes: proceedings: May 18-23, 2003, Sheraton Sand Key Resort, Clearwater Beach, Florida, USA

Atmospheric transport of mold spores in clouds of desert dust
E.A. Shinn, Dale W. Griffin, D.B. Seba
2003, Archives of Environmental Health (58) 498-504
Fungal spores can be transported globally in clouds of desert dust. Many species of fungi (commonly known as molds) and bacteria--including some that are human pathogens--have characteristics suited to long-range atmospheric transport. Dust from the African desert can affect air quality in Africa, Europe, the Middle East, and the Americas....
Orogenic tectonism on Io
Windy L. Jaeger, Elizabeth P. Turtle, Laszlo P. Keszthelyi, Jani Radebaugh, A.S. McEwen, Robert T. Pappalardo
2003, Journal of Geophysical Research E: Planets (108)
We catalog 143 Ionian mountains (montes) and mountain‐like features (mensae, tholi, plana, and small peaks) in order to investigate orogenic tectonism on Io. From this comprehensive list, we select 96 mountains for which there are sufficient coverage and resolution to discern spatial relationships with surrounding geologic features. Three of the...
Geomorphology, acoustic backscatter, and processes in Santa Monica Bay from multibeam mapping
James V. Gardner, Peter Dartnell, Larry A. Mayer, John E. Hughes Clarke
2003, Marine Environmental Research (56) 15-46
Santa Monica Bay was mapped in 1996 using a high-resolution multibeam system, providing the first substantial update of the submarine geomorphology since the initial compilation by Shepard and Emery [(1941) Geol. Soc. Amer. Spec. Paper 31]. The multibeam mapping generated not only high-resolution bathymetry, but also coregistered, calibrated acoustic backscatter...
Quantifying migratory delay: A new application of survival analysis
Theodore Castro-Santos, Alex Haro
2003, Canadian Journal of Fisheries and Aquatic Sciences (60) 986-996
Statistical techniques commonly used in fish passage research fail to adequately quantify delays incurred at obstacles, or the effects of modifications to those obstacles on passage rates. Analyses of telemetry data describing these effects can be misleading, particularly when passage route of some individuals is not established (e.g., because of...
Trends in suspended-sediment concentration at selected stream sites in Kansas, 1970–2002
James E. Putnam, Larry M. Pope
2003, Water-Resources Investigations Report 2003-4150
Knowledge of erosion, transport, and deposition of sediment relative to streams and impoundments is important to those involved directly or indirectly in the development and management of water resources. Monitoring the quantity of sediment in streams and impoundments is important because: (1) sediment may degrade the water quality of streams...
Methods of analysis by the U.S. Geological Survey National Water Quality Laboratory-Determination of gasoline oxygenates, selected degradates, and BTEX in water by heated purge and trap/gas chromatography/mass spectrometry
Donna L. Rose, Mark W. Sandstrom
2003, Water-Resources Investigations Report 2003-4079
A method for determination of the alkyl ethers u sed as gasoline oxygenates [ethyl tert-butyl ether (ETBE), methyl tert-butyl ether (MTBE), diisopropyl ether (DIPE), and tert-amyl methyl ether (TAME)], some of their main degradates [acetone, methyl acetate, tert-butyl alcohol (tBA), and tert-amyl alcohol (tAA)], and BTEX (benzene, toluene, ethylbenzene, and...
Biosolids, soils, ground-water, and streambed-sediment data for a biosolids-application area near Deer Trail, Colorado, 1999
Michael R. Stevens, Tracy J.B. Yager, D. B. Smith, J.G. Crock
2003, Open-File Report 2002-51
In January 1999, the U.S. Geological Survey began an expanded monitoring program near Deer Trail, Colorado, in cooperation with the Metro Wastewater Reclamation District and the North Kiowa Bijou Groundwater Management District. Monitoring components were biosolids, soils, crops, ground water, and streambed sediments. The monitoring program addresses concerns from the...
