Calibration of a simple oilspill trajectory model using the Argo Merchant spill
Timothy Wyant
1978, Open-File Report 78-334
An oil spill risk analysis was conducted to determine the relative envionmental hazards of developing oil in different regions of the Eastern Gulf of Mexico Outer Continental Shelf lease area. The study analyzed the probability of spill occurrence, likely paths of the spills, and locations in space and time of...

Hydrologic reconnaissance of the Yampa River during low flow, Dinosaur National Monument, northwestern Colorado
Timothy Doak Steele, Dennis A. Wentz, James W. Warner
1978, Open-File Report 78-226
A hydrologic reconnaissance of a 74-kilometer reach of the Yampa River in Dinosaur National Monument was made during low flow in mid-August 1976. Stream discharge, which was measured along this reach every 16 to 24 kilometers, ranged from 9.4 to 10.6 cubic meters per second. Variations in streamflow were explained,...
Update and revision of brachiopod collections of the Phosphoria, Park City, and Shedhorn Formations (Permian) of the U.S. Geological Survey
Bruce R. Wardlaw
1978, Open-File Report 78-692
The numerous collections amassed by the U.S. Geological Survey's study of the Western Phosphate Field have been examined. Many collections already have been discarded; and only those still housed at the Smithsonian are dealt with in this paper. Future studies of the biostratigraphy and paleogeography of the Phosphoria Formation and...
A simple-harmonic model for depicting the annual cycle of seasonal temperatures of streams
Timothy Doak Steele
1978, Open-File Report 78-155
Due to economic or operational constraints, stream-temperature records cannot always be collected at all sites where information is desired or at frequencies dictated by continuous or near-continuous surveillance requirements. For streams where only periodic measurements are made during the year, and that are not appreciably affected by regulation or by...

Nuclear power reactor sites in the southeastern United States
Mareta West
1978, Open-File Report 78-256
This report describes nuclear power reactor sites in the southeastern United States. The map indicates the location of all sites as of July 1976 in the conterminous United States, and a later published report will include all sites. The project is one of several in the National Environmental Overview Program...

Least-squares refinement of powder diffraction data for unit cell parameters: Program listing for DEC 10 computer
George Van Trump, Phoebe L. Hauff
1978, Open-File Report 78-431
This FORTRAN computer program is a time-sharing version of the classic program of Appleman and Evans (1973) and Evans, Appleman, and Handwerker (1963), which indexes powder patterns and refines unit-cell dimensions. The program, originally written to be processed in batch mode for an IBM computer, was modified to run in...

Sediment yields for selected streams in Texas
C.T. Welborn, R. Bryce Bezant
1978, Open-File Report 78-83
The U.S. Geological Survey began a study to determine sediment yields for selected streams in Texas during the 1966 water year to provide information for areas in which sediment-yield data were meager or lacking. These data will aid in delineating problem areas and planning for water-resources development in the State....
Hydrologic environment of the Silurian salt deposits in parts of Michigan, Ohio, and New York
Stanley E. Norris
1978, Open-File Report 78-684
The aggregate thickness of evaporites (salt, gypsum, and anhydrite) in the Silurian Salina sequence in Michigan exceeds 1200 feet in areas near the periphery of the Michigan basin, where the salt beds are less than 3000 feet below land surface. In northeast Ohio the aggregate thickness of salt beds is...
