Purpose: [9/29: Updated cruise track.] [9/28: Corrected participant list.] [Revised cruise plan on 9/10 to update participant list and embellish equipment list.] R/V Western Flyer operations are scheduled to be conducted in October 2015 as part of the Coordinated Canyon Experiment (CCE). The CCE is a large multi-institution program with partners and partial support from the United Kingdom’s Natural Environment Research Council (NERC), the United States Geological Survey (USGS), and Ocean University of China (OUC) with the goal of directly documenting the passage of sediment density flows through the axis of Monterey Canyon. The program involves a field experiment that will run from the fall of 2015 to the spring of 2017 involving equipment deployed within the axis of the Canyon from ~200 m to ~1900 m water depths (Figures 1 & 2). The deployments and servicing will depend on Western Flyer, Carson, and Paragon cruises as well as wave glide operations. A summary of the full CCE is outlined as Appendix 1 of the 2015 MBARI internal proposal for the Continental Margins project (901023). The Western Flyer will be focused on the BIN, moorings (MS6-MS7), which will be deployed in ≥1800 m water depths and the master AMT frame which is also equipped with a BED and STED. Western Flyer Operations: Monday October 12th mobilization day. Oct. 13 - 00:90L depart on plus 3 tide. Steam 30 km to BIN site. • Deploy BIN in 1832 m - (Chaffey, O’Reilly, Parsons) (Wireline lowering using Spectra line from CTD winch on upper deck and acoustic release. Details of the deployment are outlined in Chaffey’s ppt file and in presentations to Captain McKee and ROV Doc Ricketts ROV pilots during June 8, 2015 design review meeting. Oct. 14 • Doc Ricketts dive on BIN to check status, install Aquadopp side-arm for downward looking ADCP and clear away release straps. Oct. 15 • Deploy 1800 m (McLane profiler- Lovera, Barry Group, Gwiazda) (from one of three drum segments on the MacArtney winch mounted on the on lower deck) • Deploy 1900 m mooring (Whaling, Buck - Barry group) (from one of three drum segments on the MacArtney winch mounted on the lower deck). Oct. 16 • Deploy master AMT-BED-STED frame ~250 m (Bird, Kieft), lowered on Spectra line and acoustic release. • Dive on frame to a check status and remove deployment harnesses. • 16:00 L return to Moss Landing.
