Status: Completed

Organization(s): USGS, Pacific Coastal and Marine Science Center, U.S. Environmental Protection Agency

Funding Program(s):

Principal Investigator(s): James Conrad, Holly Ryan

Affiliate Investigator(s): Doug Pabst (EPA, R2, , Chief Scientist), Allan Ota

Information Specialist(s): James Conrad

Data Type(s): Location-Elevation: Navigation, Seismics: Boomer, Seismics: Sparker

Scientific Purpose/Goals: This cruise aboard the Ocean Survey Vessel (OSV) Bold, a cooperative effort between the U.S. Environmental Protection Agency (EPA) and the U.S. Geological Survey (USGS), is comprised of six integrated components; 1-4 (cancelled/postponed) 5 and 6 during this field activity. 1) seafloor sampling (box corer) at three EPA disposal sites to confirm the quality and cleanliness of disposed materials, 2) seafloor sampling (box corer) at five offshore southern California Borderland deepwater basins in support of a mass balance study of discharged tDDT, 3) 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, 4) seafloor sampling (box corer) at EPA disposal sites and in deepwater offshore basins to collect biological voucher samples 5) collection of high-resolution seismic-reflection profiles offshore of Huntington Beach, CA to assess neotectonic activity (recency of fault motion and potential for tectonic-related hazards), and (6) seafloor sampling (gravity corer) to age-date recency of fault motion identified in (5) above and to support sediment transport studies.
