Gary J. Barton, Edward H. Moran, Charles Berenbrock
2004, Open-File Report 2004-1045
The declining population of Kootenai River white sturgeon, which was listed as an Endangered Species in 1994, has prompted a recovery team to assess the feasibility of various habitat enhancement scenarios to reestablish white sturgeon populations. As the first phase in this assessment, the U.S. Geological Survey collected stream channel...

SAM 2.1—A computer program for plotting and formatting surveying data for estimating peak discharges by the slope-area method
J.E. Hortness
2004, Fact Sheet 2004-3028
The U.S. Geological Survey (USGS) measures discharge in streams using several methods. However, measurement of peak discharges is often impossible or impractical due to difficult access, inherent danger of making measurements during flood events, and timing often associated with flood events. Thus, many peak discharge values often are calculated after...

Digital elevation extraction from multiple MTI data sets
Jeffrey A. Mercier, Robert A. Schowengerdt, James C. Storey, Jody L. Smith
2004, Conference Paper
The Digital Elevation Model (DEM) extraction process traditionally uses a stereo pair of aerial photographs that are sequentially captured using an airborne metric camera. Standard DEM extraction techniques have been naturally extended to utilize satellite imagery. However, the particular characteristics of satellite imaging can cause difficulties in the DEM extraction...

Molecular markers and their use in environmental organic geochemistry
Robert P. Eganhouse
2004, Book chapter, The geochemical society special publications
Molecular markers are organic substances that carry information about sources of organic matter or contamination. The source/marker relation can be used to indicate the presence of a given source material (qualitative), or, under appropriate conditions, to estimate the amount of a source material (quantitative source apportionment) in the environment. Assemblages...
