U.S. stream flow measurement and data dissemination improve
Robert M. Hirsch, John E. Costa
2004, Eos, Transactions, American Geophysical Union (85) 197-2003
Stream flow information is essential for many important uses across a broad range of scales, including global water balances, engineering design, flood forecasting, reservoir operations, navigation, water supply, recreation, and environmental management. Growing populations and competing priorities for water, including preservation and restoration of aquatic habitat, are spurring demand for...
Core-scale permeability of an actively venting, felsic-hosted hydrothermal system: The PACMANUS Hydrothermal Field
L.B. Christiansen, G.J. Iturrino
2004, Conference Paper, Proceedings of the Ocean Drilling Program: Scientific Results
Permeability of the ocean crust is one of the most crucial parameters for constraining submarine fluid flow systems. Active hydrothermal fields are dynamic areas where fluid flow strongly affects the geochemistry and biology of the surrounding environment. There have been few permeability measurements in these regions, especially in felsic-hosted hydrothermal...

Hydrogeology, water quality, and distribution and sources of salinity in the Floridan aquifer system, Martin and St. Lucie Counties, Florida
Ronald S. Reese
2004, Water-Resources Investigations Report 2003-4242
The Floridan aquifer system is considered to be a valuable source for agricultural and municipal water supply in Martin and St. Lucie Counties, despite its brackish water. Increased withdrawals, however, could increase salinity and threaten the quality of withdrawn water. The Floridan aquifer system consists of limestone, dolomitic limestone, and...
Estimating hydraulic properties of the Floridan Aquifer System by analysis of earth-tide, ocean-tide, and barometric effects, Collier and Hendry Counties, Florida
Michael L. Merritt
2004, Water-Resources Investigations Report 2003-4267
Aquifers are subjected to mechanical stresses from natural, non-anthropogenic, processes such as pressure loading or mechanical forcing of the aquifer by ocean tides, earth tides, and pressure fluctuations in the atmosphere. The resulting head fluctuations are evident even in deep confined aquifers. The present study was conducted for the purpose...

Selected natural attenuation monitoring data, Operable Unit 1, Naval Undersea Warfare Center, Division Keyport, Washington, June 2002
Richard S. Dinicola
2004, Open-File Report 2004-1203
Previous investigations indicated that natural attenuation and biodegradation of chlorinated volatile organic compounds (CVOCs) are substantial in shallow ground water beneath the 9-acre former landfill at Operable Unit 1 (OU 1), Naval Undersea Warfare Center (NUWC), Division Keyport, Washington. The U.S. Geological Survey (USGS) has continued to monitor ground-water geochemistry...
The Cottage Lake aeromagnetic lineament: A possible onshore extension of the southern Whidbey Island fault, Washington
Richard J. Blakely, Brian L. Sherrod, Ray E. Wells, Craig S. Weaver, David H. McCormack, Kathy G. Troost, Ralph A. Haugerud
2004, Open-File Report 2004-1204
The northwest-striking southern Whidbey Island fault zone (SWIF) was mapped previously using borehole data and potential-field anomalies on Whidbey Island and marine seismic surveys beneath surrounding waterways. Abrupt subsidence at a coastal marsh on south-central Whidbey Island suggests that the SWIF experienced a MW 6.5 to 7.0 earthquake about 3000...

Drought conditions in Maine, 1999-2002: A historical perspective
Pamela J. Lombard
2004, Water-Resources Investigations Report 2003-4310
Hydrologic drought can be defined as reduced streamflow, declining ground-water levels, and (or) reductions in lake or reservoir levels. Monthly precipitation totals, annual 7-day low-flow surface-water recurrence intervals, and month-end ground-water levels from drought years 1999-2002 show that 1999-2002 was the driest period of hydrologic drought in more than 50...
