Inversion of data from electrical resistivity imaging surveys in water-covered areas
M. H. Loke, John W. Lane Jr.
2004, Exploration Geophysics (35) 266-271
Electrical resistivity imaging surveys widely used in many environmental and engineering studies have also been conducted in water-covered areas. Surveys in water-covered areas include conventional surveys using multi-electrode resistivity systems where part of the survey line crosses a river or stream, and surveys conducted entirely within a water-covered environment. Surveys...

Until 2001, HJ produced about 600 printed pages each year. This number has steadily increased, and in 2005 and 2006,<i class="EmphasisTypeItalic...
A viscoelastic damage model with applications to stable and unstable fracturing
Yariv Hamiel, Yunfeng Liu, V. Lyakhovsky, Yehuda Ben-Zion, David Lockner
2004, Geophysical Journal International (159) 1155-1165
A viscoelastic damage rheology model is presented that provides a generalization of Maxwell viscoelasticity to a non-linear continuum mechanics framework incorporating material degradation and recovery, transition from stable to unstable fracturing and gradual accumulation of non-reversible deformation. The model is a further development of the damage rheology framework of Lyakhovsky et...

Regression equations for estimating flood flows for the 2-, 10-, 25-, 50-, 100-, and 500-Year recurrence intervals in Connecticut
Elizabeth A. Ahearn
2004, Scientific Investigations Report 2004-5160
Multiple linear-regression equations were developed to estimate the magnitudes of floods in Connecticut for recurrence intervals ranging from 2 to 500 years. The equations can be used for nonurban, unregulated stream sites in Connecticut with drainage areas ranging from about 2 to 715 square miles. Flood-frequency data and hydrologic characteristics...
Acceleration and volumetric strain generated by the Parkfield 2004 earthquake on the GEOS strong-motion array near Parkfield, CA
Rodger D. Borcherdt, Malcolm J.S. Johnston, Christopher Dietel, Gary Glassmoyer, Doug Myren, Christopher Stephens
2004, Open-File Report 2004-1376
An integrated array of 11 General Earthquake Observation System (GEOS) stations installed near Parkfield, CA provided on scale broad-band, wide-dynamic measurements of acceleration and volumetric strain of the Parkfield earthquake (M 6.0) of September 28, 2004. Three component measurements of acceleration were obtained at each of the stations. Measurements of...

Effects of aquifer travel time on nitrogen transport to a coastal embayment
John A. Colman, John P. Masterson, Wendy J. Pabich, Donald A. Walter
2004, Groundwater (42) 1069-1078
Effects of aquifer travel time on nitrogen reaction and loading to Popponesset Bay, a eutrophic coastal embayment on western Cape Cod, Massachusetts, are evaluated through hydrologic analysis of flow and transport. Approximately 10% of the total nitrogen load to the embayment is intercepted by fresh water ponds and delivered to...
Quaternary tectonic setting of South-Central coastal California
William R. Lettis, Kathryn L. Hanson, Jeffrey R. Unruh, Marcia McLaren, William U. Savage, Margaret A. Keller
2004, Bulletin 1995-AA
Recent geodetic, geologic, and seismologic studies show that the south-central coast of California is a region of active Quaternary deformation. Northeast-directed crustal shortening is occurring in a triangular-shaped region between the Hosgri-San Simeon fault system on the west, the Southern Coast Ranges on the northeast, and the western Transverse Ranges...
Topographic map of the Tithonium Chasma Region of Mars, MTM 500k -05/277E OMKT
Water Resources Division, U.S. Geological Survey
2004, IMAP 2806
This map, compiled photogrammetrically from Viking Orbiter stereo image pairs, is part of a series of topographic maps of areas of special scientific interest on Mars. The figure of Mars used for the computation of the map projection is an oblate spheroid (flattening of 1/176.875) with an equatorial radius of...
Are diseases increasing in the ocean?
Kevin D. Lafferty, James W. Porter, Susan E. Ford
2004, Annual Review of Ecology, Evolution, and Systematics (35) 31-54
Many factors (climate warming, pollution, harvesting, introduced species) can contribute to disease outbreaks in marine life. Concomitant increases in each of these makes it difficult to attribute recent changes in disease occurrence or severity to any one factor. For example, the increase in disease of Caribbean coral is postulated to...
VTM plots as evidence of historical change: Goldmine or landmine?
Jon E. Keeley
2004, Madroño (51) 372-378
VTM (Vegetation Type Map) plots comprise a huge data set on vegetation composition for many parts of California collected mostly between 1929 and 1935. Historical changes in vegetation have been inferred by sampling these areas many decades later and evaluating the changes in plant dominance. VTM plots can not be...
Ground water recharge and discharge in the central Everglades
Judson W. Harvey, Steven L. Krupa, James M. Krest
2004, Groundwater (42) 1090-1102
Rates of ground water recharge and discharge are not well known in the central Everglades. Here we report estimates of ground water recharge and discharge at 15 sites in the Everglades Nutrient Removal Project and in Water Conservation Area 2A (WCA-2A), along with measurements of hydraulic properties of peat at...
Style and rate of quaternary deformation of the Hosgri Fault Zone, offshore south-central coastal California

Margaret A. Keller, editor(s)
2004, Bulletin 1995-BB
The Hosgri Fault Zone is the southernmost component of a complex system of right-slip faults in south-central coastal California that includes the San Gregorio, Sur, and San Simeon Faults. We have characterized the contemporary style of faulting along the zone on the basis of an integrated analysis of a broad...

2004, IEEE Transactions on Geoscience and Remote Sensing (42) 2691-2694
The current Thematic Mapper (TM) class of Landsat sensors began with Landsat-4, which was launched in 1982. This series continued with the nearly identical sensor on Landsat-5, launched in 1984. The final sensor in the series was the Landsat-7 Enhanced Thematic Mapper Plus (ETM+), which was carried into orbit in...

Launched in April 1999, the Landsat-7 Enhanced Thematic Mapper Plus (ETM+) instrument is in its sixth year of operation. The ETM+ instrument has been the most stable of any of the Landsat instruments. To date, the best onboard calibration source for the reflective bands has been the Full Aperture Solar...
Evaluating the effect of salinity on a simulated American Crocodile (Crocodylus acutus) population with applications to conservation and Everglades restoration
Paul M. Richards, Wolf M. Mooij, Donald L. DeAngelis
2004, Ecological Modelling (180) 371-394
Everglades restoration will alter the hydrology of South Florida, affecting both water depth and salinity levels in the southern fringes of the Everglades, the habitat of the endangered American crocodile (Crocodylus acutus). A key question is what the effects of these hydrologic changes will be on the crocodile population. Reliable...
