2001, Open-File Report 2001-100
Suspended-sediment concentration data were collected in San Francisco Bay during water year 1999 (October 1, 1998-September 30, 1999). Optical backscatterance sensors and water samples were used to monitor suspended sediment at one site in Suisun Bay, three sites in San Pablo Bay, two sites in Central San Francisco Bay, and...
Method of analysis and quality-assurance practices by the U. S. Geological Survey Organic Geochemistry Research Group—Determination of four selected mosquito insecticides and a synergist in water using liquid-liquid extraction and gas chromatography/mass spectrometry
L.R. Zimmerman, A.P. Strahan, E.M. Thurman
2001, Open-File Report 2001-273
A method of analysis and quality-assurance practices were developed for the determination of four mosquito insecticides (malathion, metho-prene, phenothrin, and resmethrin) and one synergist (piperonyl butoxide) in water. The analytical method uses liquid-liquid extraction (LLE) and gas chromatography/mass spectrometry (GC/MS). Good precision and accuracy were demonstrated in reagent water, urban...

2001, Open-File Report 2001-56
A marine K-T boundary interval has been identified throughout the Badlands National Park region of South Dakota. Data from marine sediments suggest that deposits from two asteroid impacts (one close, one far away) may be preserved in the Badlands. These impact-generated deposits may represent late Maestrichtian events or possibly the...
