Summary of Field Work: |
Field work will consist of yearly cruises that combine shipboard lidar sensing with airborne overflights with a hyperspectral imaging system. Both of these sensors will be capable of measuring polarization state of the water. The cruises will be in various environments such that the utility of using polarized imagery and lidar can be evaluated for retrieval of underwater properties such as particle types, layer formation, bottom composition, and whether material is man-made or natural. |

|
Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations: |
The F.G. Walton Smith has been requested since the test will include a shipboard lidar operations. The Walton Smith with the moon pool and the catamaran style makes operations off the bow of ship possible with the lidar. This is extremely important since ship configuration and stability will be required for lidar operational use. |

Short Description of Op Area
for use in schedules: |
SouthFlorida |
| Description of Op Area: |
Several optical stations will be done on a line from 25.0 N 81.25W to about 25.5 N and 83.4 W. The operations will consist of towing a scanfish and having lidar on with speed of about 4 knots. |

|
Are you or any member in your science party bringing in any science equipment items which are regulated for export by the International Traffic in Arms Regulations (ITAR) and/or the Export Administration Regulations (EAR)?
|
No |
If yes, have you applied for the necessary permits through your export control office?
|
No |

Requested Start Port |
Intermediate Port(s) |
Requested End Port |

Miami, FL, USA |
None |
Miami, FL, USA |
Explanation/justification for requested
ports and dates of intermediate stops
or to list additional port stops |
The Walton Smith operates out of Florida and it would be easiest to load and disembark from Miami since a lidar will be utilized. The operational area will be just west of Miami but on the Gulf of Mexico side of Florida. |
