This dataset is used to display the locations of sound velocity profiles (SVP, also referred to as sound speed profiles), as well as the SVP data, collected during a 2017 USGS survey on Lake Powell in the Glen Canyon National Recreation Area of Utah and Arizona. The sound velocity profiles document water column sound speed variability during the survey, and were used during processing to account for refraction artifacts present within the multibeam bathymetric data. The dataset contains graphs of sound velocity vs. depth at each profile location, as well as a shapefile with the location in Geographic Coordinate System (GCS) WGS 84 latitude and longitude, the time of day, and date of collection.

For the shapefile and web services data, the user must have software capable of reading shapefile format, or GIS software capable of utilizing web mapping or feature services. The ASCII SVP files can be read with a text editor. PNG files can be viewed with any PNG image viewing software. The Zip files must be uncompressed to utilize the ASCII text files or view the images.
