AKA: none

Other ID: W-4-06-MB,MBARI T1051,MBARI T1052 MBARI T1053 MBARI T1054 MBARI T1055 MBARI T1056 MBARI T1058

Status: Completed

Organization(s): USGS, Pacific Coastal and Marine Science Center, Monterey Bay Aquarium Research Institute (MBARI)

Funding Program(s): California Urban Ocean (MU034)

Principal Investigator(s):

Affiliate Investigator(s): Charlie Paull, Mark Chaffey

Information Specialist(s): Bill Normark

Data Type(s): Location-Elevation: Navigation, Sampling: Geology

Scientific Purpose/Goals: The cruise was split to reflect two different operations: use the ROV to collect samples from submarine canyons (part 1) and then to deploy cable for the sea floor observatory taking a few additional vibracore samples near the observatory (part 2). A brief port stop on 02 Nov (JD306) for personnel transfers.


Start Port/Location: Moss Landing

End Port/Location: Moss Landing

Start Date: 2006-10-31

End Date: 2006-11-07

Equipment Used: GPS, vibratingcore

Information to be Derived: Continue a sampling program to look at sediment transport in smaller canyons south of Pt. Sur, e.g., Sur, Partington, Lucia, and Little Lucia Canyons. Obtain additional samples to evaluate the recent history of sediment transport through Monterey Canyon in the area of the Shepard Meander. This is a continuation of earlier collaborative work with MBARI scientists.

Notes: (1) Station IDs reflect the Tiburon dive numbers set by MBARI. (2) Sample numbers for the push cores are generally not consecutive but reflect permanent labels on coring and other devices that are randomly chosen before each dive, and many of the push cores are reused in later dives. USGS sample protocol could not used during dives except for the Activity ID (W-1-05-SC). (3) Sample numbers recorded in FACS reflect only those samples that will be brought to the USGS for logging, description, and, in most cases, archiving.
