Summary

This data release presents bathymetric and topographic data from surveys performed between 2017 and 2018 in the Cache Slough Complex and the Sacramento River Deep Water Ship Channel (DWSC), northern Sacramento-San Joaquin Delta, California. The shallow, highly vegetated aquatic habitats of this region necessitated a variety of survey platforms and techniques (fig. 1). In the deeper channels, swath bathymetry data were collected using a 234.5 kHz interferometric sidescan sonar pole-mounted to the 26-ft R/V San Lorenzo. In smaller channels and shallow areas not accessible with the larger survey vessel, swath bathymetry data were acquired with Kelpfly, a personal watercraft (PWC) equipped with a 468 kHz interferometric sidescan sonar.

Purpose

These data were collected in support of ongoing field experiments and numerical modeling with the U.S. Bureau of Reclamation to improve our understanding of habitat quality, the influence on various landscape features on ecosystem function, and the effects of restoration actions in the Sacramento–San Joaquin Delta. These data are intended for science researchers, students, policy makers, and the general public.
