These data were released prior to the October 1, 2016 effective date for the USGS’s policy dictating the review, approval, and release of scientific data as referenced in USGS Survey Manual Chapter 502.8 Fundamental Science Practices: Review and Approval of Scientific Data for Release. The digital data set delineates the outer boundary of each major discharge area evaluated as part of the study. These areas were used to refine estimates of ground-water discharge throughout the Death Valley regional flow system. As delineated, boundaries include all phreatophytic vegetation and moist soil areas within a discharge area. The boundaries were used to focus efforts associated with classifying the different vegetation...

The digital data set provides locations and general descriptions of sites instrumented to collect micrometeorological data from which mean annual ET rates were computed. Sites are located in Ash Meadows and Oasis Valley, Nevada. Data were collected December 1993 through present.

These data were released prior to the October 1, 2016 effective date for the USGS’s policy dictating the review, approval, and release of scientific data as referenced in USGS Survey Manual Chapter 502.8 Fundamental Science Practices: Review and Approval of Scientific Data for Release. The digital data set provides point locations and general descriptions of areas photographed to document sites visited during a study to refine current estimates of ground-water discharge from the major discharge areas of the Death Valley regional flow system. Photographs were taken 1994-99. Sites were used as controls to better improve the delineation of ET (evapotranspiration) units classified using spectral methods throughout...
ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
