Reprocessed legacy seismic-reflection data from USGS field activity B-1-72-SC collected offshore central and southern California

Seismic-reflection data were collected offshore central and southern California in 1972 aboard the USNS Bartlett (USGS Field Activity B-1-72-SC). In 2021 these legacy data were reprocessed to improve accuracy and geologic resolvability of Californias continental margin. The effort to rescue and reprocess these legacy seismic-reflection data profiles was supported by Pacific Gas and Electric (PG&E) through a USGS Cooperative Research and Development Agreement (CRADA). Seismic-reflection data are presented in two zip files; one zip file contains data collected in the UTM zone 10N geographic area offshore of central California, the other zip file contains data collected in the UTM zone 11N geographic area offshore of southern California.
