Dataset description: Reprocessed legacy seismic-reflection data from USGS field activity B-1-72-SC collected offshore southern California

Seismic-reflection data were collected offshore 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 California's continental margin.
