Summary

This portion of the USGS data release presents elevation data for Little Holland Tract in the Sacramento-San Joaquin River Delta, California. During May and June of 2015, a team of scientists from the USGS Pacific Coastal and Marine Science Center (PCMSC) conducted multiple surveys (USGS Field Activity 2015-642-FA) to collect topographic and bathymetric data in Little Holland Tract, located in the Sacramento-San Joaquin River Delta between Liberty Island and the Sacramento Deep Water Ship Channel. Bathymetric mapping was conducted at high tide using a personal watercraft (PWC) equipped with echosounders. The PWC platform consisted of survey grade Trimble R7 global navigation satellite system (GNSS) receivers with Zephyr 2 antennas, [...]
