An update of Quaternary faults of central and eastern Oregon
Ray J. Weldon II, D.K. Fletcher, E.M. Weldon, K.M. Scharer, P.A. McCrory
2002, Open-File Report 2002-301
This is the online version of a CD-ROM publication. We have updated the eastern portion of our previous active fault map of Oregon (Pezzopane, Nakata, and Weldon, 1992) as a contribution to the larger USGS effort to produce digital maps of active faults in the Pacific Northwest region. The 1992...
Composite regional catalogs of earthquakes in the former Soviet Union
Tatyana Rautian, William Leith
2002, Open-File Report 2002-500
Seismological study of the territory of the former Soviet Union developed in the 20th century with the approach of maintaining constant observations with standard instrumentation and methods of data processing, determining standardized parameters describing the seismic sources, and producing regular summary publications. For most of the century, event data were...
Possible sources of nitrate in ground water at swine licensed-managed feeding operations in Oklahoma, 2001
Mark F. Becker, Kathy D. Peter, Jason Masoner
2002, Water-Resources Investigations Report 2002-4257
Samples collected and analyzed by the Oklahoma Department of Agriculture, Food, and Forestry from 1999 to 2001 determined that nitrate exceeded the U.S. Environmental Protection Agency maximum contaminant level for public drinking-water supplies of 10 milligrams per liter as nitrogen in 79 monitoring wells at 35 swine licensed-managed feeding operations...
Streamflow characteristics for selected stations in and near the Grand Mesa, Uncompahgre, and Gunnison National Forests, southwestern Colorado
Gerhard Kuhn
2002, Open-File Report 2002-471
The U.S Geological Survey, in cooperation with the Grand Mesa, Uncompahgre, and Gunnison National Forests, began a study in 2000 to develop selected streamflow characteristics for 60 streamflow-gaging stations in and near the Grand Mesa, Uncompahgre, and Gunnison National Forests. The study area is located in southwestern Colorado within the...
Trends in Streamflow, River Ice, and Snowpack for Coastal River Basins in Maine During the 20th Century
Robert W. Dudley, Glenn A. Hodgkins
2002, Water-Resources Investigations Report 2002-4245
Trends over the 20th Century were examined in streamflow, river ice, and snowpack for coastal river basins in Maine. Trends over time were tested in the timing and magnitude of seasonal river flows, the occurrence and duration of river ice, and changes in snowpack depth, equivalent water content, and density....
Digital recovery, modification, and analysis of Tetra Tech seismic horizon mapping, National Petroleum Reserve Alaska (NPRA), northern Alaska
R. W. Saltus, Christopher S. Kulander, Christopher J. Potter
2002, Open-File Report 2002-111
We have digitized, modified, and analyzed seismic interpretation maps of 12 subsurface stratigraphic horizons spanning portions of the National Petroleum Reserve in Alaska (NPRA). These original maps were prepared by Tetra Tech, Inc., based on about 15,000 miles of seismic data collected from 1974 to 1981. We have also digitized...
