2006, Photogrammetric Engineering and Remote Sensing (72) 1129-1135
The Landsat-7 Enhanced Thematic Mapper Plus instrument has two selectable gains for each spectral band. In the acquisition plan, the gains were initially set to maximize the entropy in each scene. One unintended consequence of this strategy was that, at times, dense vegetation saturated band 4 and deserts saturated all...
A global perspective on the use, sales, exposure pathways, occurrence, fate and effects of veterinary antibiotics (VAs) in the environment
Ajit K. Sarmah, Michael T. Meyer, Alistair B.A. Boxall
2006, Chemosphere (65) 725-759
Veterinary antibiotics (VAs) are widely used in many countries worldwide to treat disease and protect the health of animals. They are also incorporated into animal feed to improve growth rate and feed efficiency. As antibiotics are poorly adsorbed in the gut of the animals, the majority is excreted unchanged in...

Evidence for the role of infectious disease in species extinction and endangerment
Katherine F. Smith, Dov F. Sax, Kevin D. Lafferty
2006, Conservation Biology (20) 1349-1357
Infectious disease is listed among the top five causes of global species extinctions. However, the majority of available data supporting this contention is largely anecdotal. We used the IUCN Red List of Threatened and Endangered Species and literature indexed in the ISI Web of Science to assess the role of...
Topomapping of Mars with HRSC Images, ISIS, and a commercial stereo workstation
Randolph L. Kirk, Elpitha Howington-Kraus, Donna M. Galuszka, Bonnie L. Redding, Trent M. Hare
2006, Conference Paper, Symposium of ISPRS Commission IV
We demonstrate that the freely available USGS planetary cartography software package ISIS and the commercial photogrammetric software SOCET SET jointly provide a complete environment for the processing of Mars Express High Resolution Stereo Camera (HRSC) images. Capabilities include bundle adjustment, automated production and interactive editing of stereo digital terrain models...

Annual ground-water discharge by evapotranspiration from areas of spring-fed riparian vegetation along the eastern margin of Death Valley, 2000-02
Randell J. Laczniak, J. LaRue Smith, Guy A. DeMeo
2006, Scientific Investigations Report 2006-5145
Flow from major springs and seeps along the eastern margin of Death Valley serves as the primary local water supply and sustains much of the unique habitat in Death Valley National Park. Together, these major spring complexes constitute the terminus of the Death Valley Regional Ground-Water Flow System--one of the...
Comparison of ground-water quality in samples from selected shallow and deep wells in the central Oklahoma aquifer, 2003-2005
Carol Becker
2006, Scientific Investigations Report 2006-5084
The aquifer units of the Central Oklahoma aquifer underlie about 2,890 square miles of central Oklahoma and are used extensively to supply water for municipal, domestic, industrial, and agricultural needs. The Central Oklahoma aquifer also is commonly referred to as the Garber-Wellington aquifer because the Garber Sandstone and Wellington Formation...
