Project Title: SENSORS: ALOHA Mooring Sensor Network and Adaptive Sampling Project Status: Submitted
Principal Investigator: Bruce M. Howe, UH_SOEST Project Institution: UW_APL
Project ID: 100200 Version #: 4

Summary of Field Work: ALOHA/MARS Mooring Sensor Network/Profiler

We will be deploying (early spring 2008) and recovering (late summer 2008) a mooring network system connected via a seafloor cable to the MARS Observatory node at ~900 m depth in Monterey Bay. The system includes: 1.7 km of seafloor cable connected to the MARS node, a seafloor secondary node, and the mooring. The latter includes an instrument package (dual CTDO2, optical backscatter/fluorometer BB2F, 25 kHz WHOI acoustic micromodem) at the bottom, a MMP profiler (CTDO2, BB2F, acoustic current meter) and inductive docking station, subsurface float at 165 m with secondary node, ADCP, and instrument package (as seafloor + boradband hydrophone). We will need dynamic positioning, given the mooring deployment and recovery method, possible congestion around the site, and the contingency to recovery/redeploy. We will use the SIO TSE multi-bay winch system on the UNOLS ship. We will be using the MBARI ROVs Ventana or Tiberon with their respective support vessels to lay the seafloor cable, install the secondary seafloor node, and connect the base of the mooring. (The cable and node installation will be done well before the mooring deployment to assure proper operation.) The coordination of the two ships/ROV is important during mooring deployment and the connection process.
Summary of Facility Requirements: The global class Thompson is requested for dynamic positioning, large A-frame, trawl winch, general stability, accurate navigation. These are essential for the deployment and thus the Thompson is being requested.

While we are requesting the Thompson or equivalent also for recovery, the ship requirements for recovery are less stringent. We do not need dynamic positioning. A somewhat smaller A-frame is required (details below).
Summary of other requirements and comments: On both cruises, we will need to install the SIO TSE winch that will be holding approximately 1000 m of 21mm diameter mooring cable.

Repeating Cruise?
(within same year)
No Interval:   # of Cruises: 1

Description of Repeating cruise requirements:
Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations:
On recovery, we need a minimum of 18.5 ft from the deck to the A-frame attach point (no deployment release and pennant necessary in-line for recovery). The winch needs to be on the main deck to allow load transfers (for which the ship's trawl winch is needed).

Required ship days on station: 1 day prep, 1 day recovery, 3 days weather/contingency, for 5 days total on station. Total of 6 days transit Seattle-Monterey-San Diego (weather time included).
