Summary of Field Work: |
The energetics of the internal tide and the resulting patterns of turbulence within the La Jolla Canyon System will be studied over the course of several months.
On a 7-day cruise in the late fall/early winter, 3 moorings first will be deployed along the axes of the branches at the head of the La Jolla Canyon System (1 km of the coast of La Jolla, CA). Six 25-hour CTD stations at 6 locations will then be occupied at various points within the canyon system. 2-3 months later we will return for a 1-day cruise aboard the R/V Robert Gordon Sproul in order to recover the 3 moorings. |
|
Summary of Facility Requirements: |
We will need a CTD/rosette, ADCP, mooring spooler, sufficient deck space/A-frame for mooring deployments/recoveries, and a vessel with dynamic positioning capable of keeping station above complex bathymetry and continuous CTD casting for 25 hours. |
|
Summary of other requirements and comments: |
This work is ideal for the instrument testing cruises aboard the Sally Ride or her sister ship, and is best suited for a vessel with dynamic positioning. However, the work can be accomplished aboard the R/V Robert Gordon Sproul if ship scheduling prevents the use of another vessel. |

Explanation of Science Party Requirements and Technician Requirements |
Our science party will include several engineers and technicians who are very familiar with mooring and continuous CTD casting operations. After the mooring deployments, these technicians will leave the vessel by small boat. The remaining science party will consist of two faculty, two project scientists, and several graduate students (most who are familiar with CTD operations). Since we will be operating the CTD around the clock on a newly commissioned vessel, we will need 2 technicians so that one will always be available if problems arise. |

Explain Instrumentation or Capability
requirements that could affect choice
of ship in scheduling. |
Operations will be conducted in water shallower than 500m. 25-hour stations demanding continuous CTD casting above complex bathymetry will be most safely and successfully executed aboard a ship with dynamic positioning.
