Purpose
|
|
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.
|
|
|
Information to be Derived
|
|
recency of fault motion, age dating, stratigraphy/sedimentology
|
|
|
Notes
|
|
Edwards/Lee sampling leg cancelled; Ryan/Conrad geophysical leg now B-1-08-SC

Got Help?
|
For B-1-08-SC, we would appreciate any information on -- analog materials, contract, crew, days at sea, dive count, funding, kms of navigation, national plan, NGDC Info, owner, ports, project, project number, publications, scanned materials, seismic description, station count, station description, submersible, summary, tabulated info.
