Field Activity Details for field activity W206MB

AKA: none

Other ID: W-2-06-MB,MBARI T954 to T958

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): Jim Barry

Affiliate Investigator(s): Charlie Paull

Information Specialist(s): Bill Normark

Data Type(s): Imagery: Photo, Imagery: Video, Location-Elevation: Navigation, Sampling: Biology, Sampling: Geology

Scientific Purpose/Goals: We will be servicing and re-deploying instrument packages in ~3,400 m of water in the axis of Monterey Canyon channel at Shepard Meander and on its adjacent flank. This equipment was launched during the Western Flyers Oct. 3-5, 2005 cruise. The equipment includes an ROV serviceable Remote Instrument Node (RIN), two moorings containing benthic sediment traps and a McLane profiler. The McLane profiler (MMP) will be recovered but not redeployed until the April MOOS deployment trip (April 27-May 4). A new RIN frame will be deployed on the flank of the canyon in preparation for the full-up MOOS deployment trip (April 27-May 4). We anticipate visiting this RIN with Tiburon dive to confirm that it survived the deployment and to collect samples that characterize this area of the canyon/fan channels flank. A second priority is to collect sediment samples and benthic biological samples to assess benthic community structure on the Monterey Fan, in association with the Shepard Meander project and benthic biology project. This will be done by ROV diving on remote areas of the fan away from the Monterey fan valley. Samples also may be collected using the MLML multi-corer as time and weather allow. This will be done in the middle of the cruise, after the instruments in Shepard Meander are recovered, but before they are re-deployed. In the event of poor weather and on the last day we will try to collect vibracore and sampling transect in the heads of several canyons near shore.

Vehicle(s):

Start Port/Location: Moss Landing

End Port/Location: Moss Landing

Start Date: 2006-03-21

End Date: 2006-03-27

Equipment Used: vibratingcore, pushcore, ROV, GPS, camera, multicore

Information to be Derived: Evaluate the recent history of sediment transport through Monterey Canyon and on to Monterey Fan seaward of the Shepard Meander. This is a continuation of earlier collaborative work with MBARI scientists. Initiate sampling program to look at sediment transport in several of the smaller canyons south of Pt. Sur, e.g., Sur, Partington and Lucia Canyons.

Notes: cores in Bldg. 15 refer (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.
