Summary

This part of the data release contains high-resolution acoustic-backscatter data collected by the U.S. Geological Survey (USGS) Pacific Coastal and Marine Science Center at three study locations in the Sacramento-San Joaquin Delta, California. Data were collected in Lindsey Slough in April 2017, Middle River in March 2018, and Mokelumne River in March 2018, using an interferometric bathymetric sidescan sonar systems mounted to the USGS R/V Parke Snavely. Data are provided in 1-m resolution GeoTIFF formats. These data were collected as part of a study of the effects of invasive aquatic vegetation on sediment transport in the Sacramento-San Joaquin Delta.

Purpose

The acoustic-backscatter survey was conducted as part of a cooperative project with the USGS California Water Science Center and the California Department of Fish and Wildlife to provide critical data about the impact of Invasive Aquatic Vegetation (IAV) on fish habitat and the health of marshes to agencies that manage and control IAV in the Delta. The acoustic-backscatter data were used to determine the edge of vegetation. These data are intended for science researchers, students, policy makers, and the general public. The data can be used with geographic information systems or other software to identify bathymetric features. These data are not intended to be used for navigation.
