Preliminary compilation of data for selected oil test wells in Northern California
Earl E. Brabb, Charles L. Powell II, Thomas M. Brocher
2001, Open-File Report 2001-152
Oil test wells can provide information on the depth, age, inclination, porosity, permeability, density, faulting, folding, and organic content of geologic formations mapped at the surface, or on units not recognized in surface outcrops. Formation density, as expressed in sonic and density logs commonly obtained when wells are drilled, has...
Floods of July 19-25, 1999, in the Wapsipinicon and Cedar River basins, northeast Iowa

During July 18-19, as much as 6 inches of rainfall was centered over Cerro Gordo, Floyd, Mitchell, and Worth Counties. During July 20-21, a second storm occurred in which an...
Methods of analysis by the U.S. Geological Survey Organic Geochemistry Research Group--Update and additions to the determination of chloroacetanilide herbicide degradation compounds in water using high-performance liquid chromatography/mass spectrometry
E.A. Lee, J.L. Kish, L.R. Zimmerman, E. Thurman
2001, Open-File Report 2001-10
An analytical method using high-performance liquid chromatography/mass spectrometry (HPLC/MS) was developed by the U.S. Geological Survey in 1999 for the analysis of selected chloroacetanilide herbicide degradation compounds in water. These compounds were acetochlor ethane sulfonic acid (ESA), acetochlor oxanilic acid (OXA), alachlor ESA, alachlor OXA, metolachlor ESA, and metolachlor OXA....
Selected data for sediment cores collected in Chesapeake Bay in 1996 and 1998

2001, Open-File Report 2001-194
As part of a study of recent history of the Chesapeake Bay ecosystem, one- to eight- meter long sediment cores were obtained from the mesohaline section of the Chesapeake Bay between the mouths of the Potomac and Rhode Rivers. The sediments consist of three lithofacies: coarse-grained channel deposits, restricted-estuary sands...
Continental shelf GIS for the Monterey Bay National Marine Sanctuary
Florence L. Wong, Stephen L. Eittreim
2001, Open-File Report 2001-179
A marine sanctuary is an environment where the interests of science and society meet. Sanctuary managers need access to the best scientific data available that describe the environment and environmental processes in sanctuaries. Seafloor mapping and sampling in the Monterey Bay National Marine Sanctuary have revealed new details about the...
Sea floor maps showing topography, sun-illuminated topographic imagery, and backscatter intensity of the Stellwagen Bank National Marine Sanctuary Region off Boston, Massachusetts
P. C. Valentine, T. J. Middleton, S. J. Fuller
