Summary of Field Work: |
Recovery of six deep sub-surface ADCP/string moorings in the southern Bay of Bengal (located 5-8N, 85.5-89E). The moorings were deployed on December 2013 using R/V Roger Revelle. Will conduct CTD surfvey after recovery of moorings. |
|
Summary of Facility Requirements: |
winch (TSP), CTD with bottles, shipboard ADCP and meteorological data |
|
Summary of other requirements and comments: |

Description of Repeating cruise requirements: |
|
Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations: |
All six moorings have been in water nore than 1 and half years by the time when we will pick them up, and batteries in moored ADCPs will last until July 2015. Moorings are 90 nm apart or 8 hours transit time between two moorings. Please schedule after Jenifer MacKinnon's, J/SIO -- ASIRI cruise in Bay of Bengal. Transit from another foreign port to the requested Colombo port is not included in the estimated transit time above. |

Explanation of Science Party Requirements and Technician Requirements |
We may operate 24 hours in some days; at least one Res. Tech and one compute tech. are required, We will use significant sections of the back deck. TSP winch from the UNOLS winch pool. Several CTD casts with bolltes, and some bio-optical/VMP profiling and plankton tows (upper 50 m), depending upon the availibity of time after the recovery of moorings.. |
