Vulnerability of port and harbor communities to earthquake and tsunami hazards: The use of GIS in community hazard planning
Nathan J. Wood, James W. Good
2004, Coastal Management (32) 243-269
AbstractEarthquakes and tsunamis pose significant threats to Pacific Northwest coastal port and harbor communities. Developing holistic mitigation and preparedness strategies to reduce the potential for loss of life and property damage requires community-wide vulnerability assessments that transcend traditional site-specific analyses. The ability of a geographic...
The geochemical and magnetic record of coal combustion products in West Virginia reservoir sediments and soils
Martin B. Goldhaber, Ted Callender, Richard L. Reynolds
2004, Book chapter, Geochemical investigations in earth and space sciences
Western West Virginia lies downwind from numerous coal-fired power plants along the Ohio River Valley. To test whether geochemical and mineralogical impacts from these power plants are detectable on the West Virginia landscape, we obtained reservoir cores, soils, and rocks from two separate sites in West Virginia, one in Harrison...
Environmental assessment

Geophysical investigation of the Denali fault and Alaska Range orogen within the aftershock zone of the October–November 2002, M = 7.9 Denali fault earthquake
Michael A. Fisher, Warren J. Nokleberg, N. A. Ratchkovski, Louise Pellerin, Jonathan M.G. Glen, Thomas M. Brocher, J. Booker
2004, Geology (32) 269-272
The aftershock zone of the 3 November 2002, M = 7.9 earthquake that ruptured along the right-slip Denali fault in south-central Alaska has been investigated by using gravity and magnetic, magnetotelluric, and deep-crustal, seismic reflection data as well as outcrop geology and earthquake seismology. Strong seismic reflections from within the...
Geophysical data reveal the crustal structure of the Alaska range orogen within the aftershock zone of the Mw 7.9 Denali fault earthquake
M. A. Fisher, N. Ratchkovski, Warren Nokleberg, Louise Pellerin, Jonathan M.G. Glen
2004, Bulletin of the Seismological Society of America (94) S107-S131
Geophysical information, including deep-crustal seismic reflection, magnetotelluric (mt), gravity, and magnetic data, cross the aftershock zone of the 3 November 2002 Mw 7.9 Denali fault earthquake. These data and aftershock seismicity, jointly interpreted, reveal the crustal structure of the right-lateral-slip Denali fault and the eastern Alaska Range orogen, as well as...
Linking metal bioaccumulation of aquatic insects to their distribution patterns in a mining-impacted river
Daniel J. Cain, Samuel N. Luoma, W.G. Wallace
2004, Environmental Toxicology and Chemistry (23) 1463-1473
Although the differential responses of stream taxa to metal exposure have been exploited for bioassessment and monitoring, the mechanisms affecting these responses are not well understood. In this study, the subcellular partitioning of metals in operationally defined metal-sensitive and detoxified fractions were analyzed in five insect taxa. Samples were collected...
The emplacement of pahoehoe toes: Field observations and comparison to laboratory simulations
Tracy K. P. Gregg, Laszlo P. Keszthelyi
2004, Bulletin of Volcanology (66) 381-391
We observed active pahoehoe lobes erupted on Kilauea during May-June 1996, and found a range of emplacement styles associated with variations in local effusion rate, flow velocity, and strain rate. These emplacement styles were documented and quantified for comparison with earlier laboratory experiments.At the lowest effusion rates, velocities,...
The Progreso Basin Province of Northwestern Peru and Southwestern Ecuador: Neogene and Cretaceous-Paleogene Total Petroleum Systems
Debra K. Higley
2004, Bulletin 2206-B
The Progreso Basin province (6083) in northwestern Peru and southwestern Ecuador consists of the Paleogene Santa Elena block and Peru Bank, and the Neogene Tumbes-Progreso subbasin. The Santa Elena block and Peru Bank are part of the Cretaceous-Paleogene Total Petroleum System (TPS)(608302), which contains the Cretaceous-Paleogene Santa Elena Block Assessment...
Monitoring Colonias Development along the United States-Mexico Border: A Process Application using GIS and Remote Sensing in Douglas, Arizona, and Agua Prieta, Sonora
Laura M. Norman, Angela J. Donelson, Edwin L. Pfeifer, Alven H. Lam, Kenneth J. Osborn
2004, Open-File Report 2004-1212
The U.S. Department of Housing and Urban Development (HUD) and the U.S. Geological Survey (USGS) have developed a joint project to create Internet-enabled geographic information systems (GIS) that will help cities along the United States-Mexico border deal with issues related to colonias. HUD defines colonias as rural neighborhoods in the...
Assessment of subsurface chlorinated solvent contamination using tree cores at the front street site and a former dry cleaning facility at the Riverfront Superfund site, New Haven, Missouri, 1999-2003
John G. Schumacher, Garrett C. Struckhoff, Joel G. Burken
2004, Scientific Investigations Report 2004-5049
Tree-core sampling has been a reliable and inexpensive tool to quickly assess the presence of shallow (less than about 30 feet deep) tetrachloroethene (PCE) and trichloroethene (TCE) contamination in soils and ground water at the Riverfront Superfund Site. This report presents the results of tree-core sampling that was successfully used...

Evaluation of and insights from ALFISH: a spatially explicit landscape-level simulation of fish populations in the Everglades
Holly Gaff, John Chick, Joel Trexler, Donald L. DeAngelis, Louis Gross, Rene Salinas
2004, Hydrobiologia (520) 73-86
We present an evaluation of a spatially explicit, age-structured model created to assess fish density dynamics in the Florida Everglades area. This model, ALFISH, has been used to compare alternative management scenarios for the Florida Everglades region. This area is characterized by periodic dry downs and refloodings. ALFISH uses spatially...
