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
