Nearshore bathymetry data from the Elwha River delta, Washington, January 2015 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...
