A simplified diagnostic model of orographic rainfall for enhancing satellite-based rainfall estimates in data-poor regions
Christopher C. Funk, Joel C. Michaelsen
2004, Journal of Applied Meteorology (43) 1366-1378
An extension of Sinclair's diagnostic model of orographic precipitation (“VDEL”) is developed for use in data-poor regions to enhance rainfall estimates. This extension (VDELB) combines a 2D linearized internal gravity wave calculation with the dot product of the terrain gradient and surface wind to approximate terrain-induced vertical velocity profiles. Slope,...

Lead isotopic compositions of common arsenical pesticides used in New England
Robert Ayuso, Nora Foley, Gilpin Robinson Jr., Gregory Wandless, Jeremy Dillingham
2004, Open-File Report 2004-1342
The three most important arsenical pesticides and herbicides that were extensively used on apple, blueberry, and potato crops in New England from mid-1800s to recent times are lead arsenate, calcium arsenate, and sodium arsenate. Lead arsenate was probably the most heavily used of the arsenical pesticides until it was banned...

Anthony J. Ranalli
2004, Open-File Report 2004-1296
This paper provides a detailed review of the chemical changes that occur in soil during a fire, the pathways by which nutrients are transferred from soil to surface-water bodies following a fire, and the temporal and spatial effects of fires on the concentration of nutrients in surface-water bodies during and...
The Loma Prieta, California, Earthquake of October 17, 1989 - Geologic setting and crustal structure
Ray E. Wells
2004, Professional Paper 1550-E
Although some scientists considered the Ms=7.1 Loma Prieta, Calif., earthquake of 1989 to be an anticipated event, some aspects of the earthquake were surprising. It occurred 17 km beneath the Santa Cruz Mountains along a left-stepping restraining bend in the San Andreas fault system. Rupture on the southwest-dipping fault plane...
Environmental setting, water quality, and ecological indicators of surface-water quality in the Mermentau River Basin, southwestern Louisiana, 1998-2001

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...
