Description:This project was a continuation of investigations on the continental shelf of the Southern California Bight (SCB). We sought to expand knowledge on the paleolandscape and paleoenvironment of the region off the northern Channel Islands and adjacent mainland through collection of geophysical data focused on identification of hydrocarbons and samples of identified tar seeps. To accomplish these goals, we first collated data from previous research on which the project collaborators had worked, as well as publicly available hydrocarbon data and reports from the region. From these data we created paleolandscape maps that targeted sections of the continental shelf that were subaerial during the Early Holocene and terminal Pleistocene and possibly harbored tar seeps. Next we conducted two survey cruises collecting subbottom profiler and controlled source electromagnetic (CSEM) data and co-located those areas that showed hydrocarbon activity in the CSEM and associated unique features in the subbottom data.
