R/V San Lorenzo (receive vessel) navigation and survey geometry from USGS field activity 2021-619-FA collected in April of 2021 offshore Santa Cruz, CA

Published by U.S. Geological Survey | Department of the Interior | Metadata Last Checked: January 27, 2026 | Last Modified: 2023-05-16T00:00:00Z
Navigation data were recorded for the R/V San Lorenzo (RVSL; receive vessel) during USGS field activity 2021-619-FA in April of 2021 off the coast of Santa Cruz, California. Data were collected as the RVSL maintained a nearly stationary position at the midpoint along seven depth site transects in water depths ranging between 25 and 600 meters while the R/V Parke Snavely (RVPS; source vessel) towed a sparker sound source along the transects. Navigation data and survey geometry information (offset distances and source layback position) are presented in csv format as well as a trackline shapefile.
