View new CMGDS report form

AKA: none

Other ID: none

Status: Completed

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

Funding Program(s): Coastal and marine earthquake, tsunami, and landslide active margin field studies (ZP00EQV)

Principal Investigator(s): Katherine Coble

Affiliate Investigator(s): David W. Caress, Chief Scientist, MBARI

Information Specialist(s): Katherine Coble

Data Type(s): Location-Elevation: Navigation, Seismics: Sub Bottom Profiler, Sonar: Multibeam, Sonar: Sidescan

Scientific Purpose/Goals: To collect high-resolution geophysical data needed to map and characterize deformation, if any, related to the San Gregorio Fault where the fault has been interpreted to intersect northern Monterey Canyon.

Vehicle(s): None

Start Port/Location: Moss Landing, CA

End Port/Location: Moss Landing, CA

Start Date: 2014-03-24

End Date: 2014-03-27

Equipment Used: navigation, GPS, 512 chirp-source, subbottomprofiler, multibeam, sidescansonar

Information to be Derived: high-resolution multibeam bathymetry, chirp sub-bottom profiles, and sidescan sonar to map and characterize deformation in Monterey Canyon related to recent movement along the San Gregorio Fault

Summary of Activity and Data Gathered: USGS will NOT be the permanent repository of data. Successfully collected chirp subbottom profiles and multibeam bathymetry on one additional AUV dive.

Staff: Katherine Coble

Notes: This data acquisition field activity is funded by and in collaboration with the Monterey Bay Aquarium Research Institute (MBARI). One research scientist, Katherine L. Maier (Coble), has been invited onto the acquisition cruise, will participate in data processing, and will lead data interpretations. No additional staff or overtime are needed. The mapping AUV, including multibeam bathymetry, chirp, and sidescan sonars, ship (R/V Rachel Carson), crew, and additional science and engineering personnel will be provided by MBARI.

Location:
