Summary of Field Work: |
Studies of lateral mixing in the upper ocean with dye releases, profiling floats, AUV, Gliders, drifters, towed sensor systems, and moving vessel profilers. Dye and drifters will be released and followed for 1 to 5 days as they disperse. The other systems will be used to survey the dye, currents and hydrography in the regions of the patches. Experiments will be coordinated with an airborne LIDAR dye sensing system operated by NAVAIR. |
|
Summary of Facility Requirements: |
3 ships are requested for a 21-day period, May-June 2011, 2 intermediate and 1 regional class. GPS, Shipboard ADCP, CTD winch and wire are required on all ships. Especially important are Internet capability for ship to shore communications. Also essential are smooth ship to ship, and ship to aircraft communication. Irridium will be used - conference calls will be held. Small boat operations must be practical for all of the ships to service profiling floats, AUV, and gliders if necesary. |
|
Summary of other requirements and comments: |
5 of the instrument systems planned for the experiment have their own winches. There will be one or two winches on each ship. The three ships must be scheduled together. |

Description of Repeating cruise requirements: |
|
Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations: |
Ships are chosen for capability to be off shore in May and to carry the people and equipment needed to perform the experiments. |

Explanation of Science Party Requirements and Technician Requirements |
Numbers are approximate. We will nearly fill each ship. There will be modeling and analysis groups as well as deployment and survey groups. We need at least one ship's technician on each ship, expert in communications, ADCP, and CTD systems. |

|
Explain Instrumentation or Capability
requirements that could affect choice
of ship in scheduling. |
We need continuous internet connection on each ship for coordination of the experiment through communication with an information center on shore. We also need capability of real time conferencing between ships and the shore lab.
