Dataset description: Marine sparker SEG-Y seismic data recorded using receive hydrophones
Geometry
Seismic data were recorded from the R/V San Lorenzo (RVSL, receive vessel) of a two-vessel marine sparker seismic survey conducted by the U.S. Geological Survey (USGS) in April of 2021 off the coast of Santa Cruz, California (USGS field activity 2021-619-FA). The R/V Parke Snavely (RVPS, source vessel) towed a marine sparker sound source along seven depth site transects ranging between 25 and 600 meters. The RVSL maintained a nearly stationary position at the midpoint of each transect and recorded sound data with a broadband omnidirectional Cetacean Research CR3 hydrophone positioned between 10- and 20-meters water depth below the RVSL. RVSL receive seismic data are presented in SEG-Y format. Shot point navigation are provided in an accompanying comma-delimited text file, as well as in a shapefile for visualization purposes.
