Handbook of groundwater remediation using permeable reactive barriers: Applications to radionuclides, trace metals, and nutrients
David L. Naftz, Stan J. Morrison, Christopher C. Fuller, James A. Davis, editor(s)
2003, Book
Over the last century and a half, groundwaters have become contaminated by a growing number of organic and inorganic substances ranging from petroleum-derived hydrocarbons to radioactive compounds, to cancer-causing hexavalent chromium. The importance of uncontaminated groundwater for agriculture, human consumption, and the environmental health of ecosystems is paramount to the...
A special issue devoted to gold deposits in northern Nevada: Part 2. Carlin-type Deposits
Albert H. Hofstra, David A. John, Ted G. Theodore
2003, Economic Geology (98) 1063-1067
This is the second of two special issues of Economic Geology devoted to gold deposits in northern Nevada. Readers interested in a general overview of these deposits, their economic significance, their context within the tectonic evolution of the region, and synoptic references on each gold deposit type are directed to...

Paleointensity in Hawaiian Scientific Drilling Project Hole (HSDP2): Results from submarine basaltic glass
L. Tauxe, Jeffrey J. Love
2003, Geochemistry, Geophysics, Geosystems (4)
Paleointensity estimates based on the high quality Thellier‐Thellier data from the early Brunhes (420–780 ka) are rare (only 30 in the published literature). The Second Hawaiian Scientific Drilling Project (HSDP2) drill hole recovered submarine volcanics spanning the approximate time period of 420–550 ka. These are of particular interest for absolute...
Sea otter studies in Glacier Bay National Park and Preserve: annual report 2002
James L. Bodkin, Kimberly A. Kloecker, George G. Esslinger, Daniel H. Monson, Heather A. Coletti, Janet Doherty
2003, Report
Since 1995, the number of sea otters in Glacier Bay proper has increased from around 5 to more than 1200. Sea otter distribution is mostly limited to the Lower Bay, south of Sandy Cove, and is not continuous within that area. Concentrations occur in the vicinity of Sita Reef and...

Pleistocene tephrostratigraphy and paleogeography of southern Puget Sound near Olympia, Washington
Timothy J. Walsh, Michael Polenz, Robert L. Logan, Marvin A. Lanphere, Thomas W. Sisson
Terry W. Swanson, editor(s)
2003, Book chapter, Western Cordillera and adjacent areas
Our detailed mapping in the south Puget Sound basin has identified two tephras that are tentatively correlated to tephras from Mount St. Helens and Mount Rainier dated ca. 100-200 ka and 200 ka, respectively. This, plus the observation that fluvial and lacustrine sediments immediately underlying the Vashon Drift of latest...
Arsenic in southeastern Michigan
Allan Kolker, Sheridan K. Haack, William F. Cannon, D.B. Westjohn, M.-J. Kim, Laurel G. Woodruff
A. H. Welch, Kenneth G. Stollenwerk, editor(s)
2003, Book chapter, Arsenic in ground water
Arsenic levels exceeding 10 μg/L are present in hundreds of private supply wells distributed over ten counties in eastern and southeastern Michigan. Most of these wells are completed in the Mississippian Marshall Sandstone, the principal bedrock aquifer in the region, or in Pleistocene glacial or Pennsylvanian bedrock aquifers. About 70%...
Earth as Art 2: a satellite perspective
Water Resources Division, U.S. Geological Survey
2003, Report
The images in Earth as Art 2 are grouped by continent or region. In this catalog, they are set against a background image of part of the continent or region from which they come. However, their placement on the background does not necessarily correlate with their true geographic location. The...

Potential effects of organic carbon production on ecosystems and drinking water quality
Larry R. Brown
2003, San Francisco Estuary and Watershed Science (1)
Restoration of tidal wetlands in the Sacramento-San Joaquin Delta (Delta) is an important component of the Ecosystem Restoration Program of the CALFED Bay-Delta Program (CALFED). CALFED is a collaborative effort among state and federal agencies to restore the ecological health and improve water management of the Delta and San Francisco...

An introduction to the San Francisco Estuary tidal wetlands restoration series
Larry R. Brown
2003, San Francisco Estuary and Watershed Science (1)
Restoration of tidal wetlands may provide an important tool for improving ecological health and water management for beneficial uses of the San Francisco Estuary (hereafter “Estuary”). Given the large losses of tidal wetlands from San Francisco Bay and the Sacramento-San Joaquin Delta in the last 150 years, it seems logical...
Projecting the success of plant restoration with population viability analysis
T.J. Bell, M.L. Bowles, A. K. McEachern
C.A. Brigham, M.W. Schwartz, editor(s)
2003, Book chapter, Population Viability in Plants.
Conserving viable populations of plant species requires that they have high probabilities of long-term persistence within natural habitats, such as a chance of extinction in 100 years of less than 5% (Menges 1991, 1998; Brown 1994; Pavlik 1994; Chap. 1, this Vol.). For endangered and threatened species that have...
