    • Reprocessed multichannel seismic reflection data acquired offshore Southern California during USGS field activity O-1-99-SC

    Metadata Updated: January 16, 2026

    Multichannel seismic (MCS) data were collected by the U.S. Geological Survey (USGS) in June of 1999 in the coastal zone and continental shelf between Los Angeles and San Diego, offshore California (USGS field activity O199SC). In 2021 these data were reprocessed to improve accuracy and resolvability of geologic structures and fault systems of California’s continental margin.
