View new CMGDS report form

AKA: none

Other ID: S-I2-09-SC

Status: Completed

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

Funding Program(s): Tsunami Hazard Potential (MU292)

Principal Investigator(s): James Conrad, Brian Edwards

Affiliate Investigator(s):

Information Specialist(s): James Conrad

Data Type(s): Sampling: Geology

Scientific Purpose/Goals: (1) Collect sediment cores (gravity corer) for C-14 dating to assess neotectonic activity (recency of fault motion and potential for tectonic-related hazards) (2) Seafloor sampling (box corer) on the mainland shelf near the Sanitation Districts of Los Angeles County (LACSD) ocean outfall at Whites Point to investigate porewater sampling protocols

Vehicle(s):

Start Port/Location: San Diego, CA

End Port/Location: San Diego, CA

Start Date: 2009-03-23

End Date: 2009-03-26

Equipment Used: gravitycore, boxcore

Information to be Derived: grain size stratigraphy/sedimentology radiometric age dates porewater chemistry recency of fault motion
