      This report is divided into seven sections: Acronyms and 
Abbreviations, Disc Contents, Navigation Data and Maps, Subbottom 
Profiles, Field Activity Logs, Federal Geographic Data Committee (FGDC) 
Metadata, and Software. Links at the top and bottom of each page provide 
access to these sections. This report contains links to the U.S. 
Geological Survey (USGS), collaborators, and other available resources if 
access to the Internet is available while viewing these documents.  
Geographic Information System (GIS) files, Society of Exploration 
Geophysicists (SEG)Y binary data files, Hypertext Markup Language (HTML) 
files and images used to produce the Web pages, and this readme file are 
also included in this report.  The Disc Contents page contains a diagram

Project Summary
      
      From March 16 to 31, 2013, the U.S. Geological Survey in 
cooperation with the Idaho Power Company conducted a geophysical survey 
to investigate sediment deposits and long-term sediment transport from 
Brownlee Dam to Hells Canyon Reservoir, Idaho/Oregon; this effort will 
help the USGS to better understand geologic processes. This report serves 
as an archive of unprocessed digital chirp subbottom profile data, 
trackline maps, navigation files, and formal FGDC metadata. Gained 
(showing a relative increase in signal amplitude) digital images of the 
seismic profiles are also provided.
