2008, Journal of Geophysical Research B: Solid Earth (113) -
The southern Whidbey Island fault zone (SWIF), as previously mapped using borehole data, potential field anomalies, and marine seismic reflection surveys, consists of three subparallel, northwest trending strands extending ∼100 km from near Vancouver Island to the northern Puget Lowland. East of Puget Sound, the SWIF makes landfall between the...
Water Availability--The Connection Between Water Use and Quality
Robert M. Hirsch, Pixie A. Hamilton, Timothy L. Miller, Donna N. Myers
2008, Fact Sheet 2008-3015
Water availability has become a high priority in the United States, in large part because competition for water is becoming more intense across the Nation. Population growth in many areas competes with demands for water to support irrigation and power production. Cities, farms, and power plants compete for water needed...

Pacific Ocean and Cenozoic evolution of climate
Mitchell Lyle, John A. Barron, Timothy J. Bralower, Matthew Huber, Annette Olivarez Lyle, A. C. Ravelo, David K. Rea, Paul A. Wilson
2008, Reviews of Geophysics (46)
The Pacific Ocean has played a major role in climate evolution throughout the Cenozoic (65–0 Ma). It is a fundamental component of global heat transport and circulation, the dominant locus of primary productivity, and, consequently, the largest reservoir for carbon exchange between the oceans and the atmosphere. A satisfactory understanding...
