    "descript": "In February 2016 the U.S. Geological Survey, Pacific Coastal and Marine Science Center in cooperation with North Carolina State University and the National Park Service collected multibeam bathymetry and acoustic backscatter data in Lake Crescent located in Olympic National Park, Washington. Data were collected using a Reson 7111 multibeam echosounder pole-mounted to the 36-foot USGS R\/V Parke Snavely. These metadata describe the multibeam acoustic-backscatter data file that is included in \"LakeCrescent_backscatter_3m_UTM10_NAD83.zip\" which is accessible from https:\/\/doi.org\/10.5066\/F7B56GW5.",
