Submarine ground-water discharge and its role in coastal processes and ecosystems
Peter W. Swarzenski, John F. Bratton, John Crusius
2004, Open-File Report 2004-1226
Submarine ground-water discharge (SGD) has recently been recognized as a phenomenon that can strongly influence coastal water and geochemical budgets and drive ecosystem change. For example, the discharge of nutrient-enriched ground water into coastal waters may contribute significantly to eutrophication and blooms of harmful algae. Similarly, the quantity of SGD...

Maps showing estimated sediment yield from coastal landslides and active slope distribution along the Big Sur coast, Monterey and San Luis Obispo Counties, California
Cheryl J. Hapke, Krystal R. Green, Kate Dallas
2004, Scientific Investigations Map 2852
The 1982-83 and 1997-98 El Ni?os brought very high precipitation to California?s central coast; this precipitation resulted in raised groundwater levels, coastal flooding, and destabilized slopes throughout the region. Large landslides in the coastal mountains of Big Sur in Monterey and San Luis Obispo Counties blocked sections of California State...

Dwight Q. Tanner, Karl K. Lee
2004, Scientific Investigations Report 2004-5061
Organochlorine pesticides were detected in unfiltered samples from Johnson Creek that were collected during a storm in March, 2002. Total DDT (the sum of DDT and its metabolites), as well as dieldrin, potentially exceeded Oregon chronic, freshwater criteria at all four Johnson Creek stream-sampling sites. The total DDT criterion was...
Characterization of the habitat of Lythrum salicaria L. in floodplain forests in western Turkey—Effects on stem height and seed production
Cengiz Ture, Nuket Akanil Bingol, Beth A. Middleton
2004, Wetlands (24) 711-716
Lythrum salicaria (purple loosestrife) is an invasive wetland perennial in North America native to Eurasia. Because light environment may limit the species’ distribution, information on the relationship of forest canopy coverage to relative height and seed set in its native environment could give insight into its control in North...
Drilling the central crater of the Chesapeake Bay Impact Structure: A first look
Ward E. Sanford, Gregory Gohn, David S. Powars, J. Wright Horton Jr., Lucy E. Edwards, Jean Self-Trail, Roger H. Morin
2004, Eos, Earth and Space Science News (85) 369-377
The late Eocene Chesapeake Bay impact structure is a well‐preserved example of one of Earth's largest impact craters, and its continental‐shelf setting and relatively shallow burial make it an excellent target for study. Since the discovery of the structure over a decade ago [Edwards et al., 2004; Poag et al., 2004], test drilling...

A suspended sediment budget for Pool 13 and La Grange Pool of the upper Mississippi River system
Robert F. Gaugush
2004, Long Term Resource Monitoring Program Technical Report 2004-T004
The suspended sediment budget for Pool 13 of the Mississippi River and La Grange Pool of the Illinois River was examined over a 3-yr period (October 1995 through September 1997). Pool 13 output was between 3.07 and 3.64 million t (metric tons) of suspended sediment annually during the study period....

2004, Water-Resources Investigations Report 2003-4050
In 1999-2001, the U.S. Geological Survey installed and sampled 27 shallow wells in the rice-growing area in southwestern Louisiana as part of the Acadian-Pontchartrain Study Unit of the National Water-Quality Assessment Program. The purpose of this report is to describe the waulity of water from shallow wells in the...

Evaluation of conceptual models of natural organic matter (humus) from a consideration of the chemical and biochemical processes of humification
Robert L. Wershaw
2004, Scientific Investigations Report 2004-5121
Natural organic matter (NOM) has been studied for more than 200 years because of its importance in enhancing soil fertility, soil structure, and water-holding capacity and as a carbon sink in the global carbon cycle. Two different types of models have been proposed for NOM: (1) the humic polymer models...
Evolutionary stability of mutualism: interspecific population regulation as an evolutionarily stable strategy
J. Nathaniel Holland, Donald L. DeAngelis, Stewart T. Schultz
2004, Proceedings of the Royal Society B (271) 1807-1814
Interspecific mutualisms are often vulnerable to instability because low benefit : cost ratios can rapidly lead to extinction or to the conversion of mutualism to parasite–host or predator–prey interactions. We hypothesize that the evolutionary stability of mutualism can depend on how benefits and costs to one mutualist vary with the...
