USGS Coastal and Marine Geology Program

Field Activity Details for field activity F207NC

AKA: F0207NC

Other ID: F-2-07-NC

Status: Completed

Organization(s): USGS, Pacific Coastal and Marine Science Center

Funding Program(s): Coastal Change Hazards (MU051), North Central Coast Mapping Project (MU208)

Principal Investigator(s): John Chin, Stephanie Ross

Affiliate Investigator(s):

Information Specialist(s): Stephanie Ross

Data Type(s): Location-Elevation: Navigation, Seismics: Sparker, Seismics: Sub Bottom Profiler

Scientific Purpose/Goals: Subbottom mapping of state waters from Ano Nuevo to San Francisco to determine evidence for previously mapped offshore faults and recency of faulting and to determine thickness of Holocene sediments. To verify surficial mapping based on multibeam with surficial features and sediment cover based on subbottom systems.


Start Port/Location: Half Moon Bay, CA

End Port/Location: Half Moon Bay, CA

Start Date: 2007-03-22

End Date: 2007-04-06

Equipment Used: GPS, 512 chirp, sparker

Information to be Derived: Isopach map of Holocene sediment thickness; Map of offshore faults and evidence for faulting and recency of fault activity
