This portion of the USGS data release presents bathymetry data collected during surveys performed on the Elwha River delta, Washington in January 2015 (USGS Field Activity Number 2015-605-FA). Bathymetry data were collected using two personal watercraft (PWCs) and a kayak, all equipped with single-beam sonar systems and global navigation satellite system (GNSS) receivers. The PWC sonar systems consisted of an Odom Echotrac CV-100 single-beam echosounder and 200 kHz transducer with a 9° beam angle. Raw acoustic backscatter returns were digitized by the echosounder with a vertical resolution of 1.25 cm. Depths from the echosounders were computed using sound velocity profiles measured using a YSI CastAway CTD during...
