Summary of Field Work: |
Fieldwork consists of multiple floating mooring deployments, Niskin rosette deployments, and use of PI provided water column sampler (MS-SID) on the CTD wire. The MS-SID is lighter than a Niskin rosette, and has been used on Oceanus and Atlantis previously. |
|
Summary of Facility Requirements: |
Niskin rosette (8-12L bottles) with CTD-O2. Rad van. Floating mooring deployment capability. Will deploy 2 connected instruments on a single floating mooring. Each is approx. 5'tall by 3'x3' wide. These instruments conduct incubation studies for 12-24 hours at a time. |
|
Summary of other requirements and comments: |
mooring technician or restech needs to be experienced in deploying floating moorings. Need other restech for CTD work. |

Dates to Avoid: |
Date are selected to work at the ETNP oxygen minimum zone during intense stratification. It is required for studying processes that occur when the core of the oxygen minimum zone is fully anoxic. |

Description of Repeating cruise requirements: |
NA |
Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations: |
13 days at each station is required to complete moored incubation studies. Atlantis or any other vessel of this size is required to accommodate our size science party and to safely deploy the floating moorings and the in situ instruments. Atlantis have been used before for operations of the in situ instruments |

 Important Info on Foreign Research Clearances
|
|
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 |
| Questions about ITAR/EAR regulations?
|
Comments about foreign clearance requirements or
description of any other special permitting requirements
(e.g., MMPA, ESA, IHA, Marine Sanctuaries, etc.) |
Foreign Clearance will be requested |

Requested Start Port |
Intermediate Port(s) |
Requested End Port |
|
San Diego, CA, USA |
None, |
San Diego, CA, USA |
Explanation/justification for requested
ports and dates of intermediate stops
or to list additional port stops |
San Diego is requested because much easier logistically and much less expensive for the science party to leave from San Diego than a Mexican port |

Explanation of Science Party Requirements and Technician Requirements |
2 technicians requested because we need a) 24-hour ops including CTD operation and b) mooring expertise. Science party team members coming from WHOI, Stony Brook, and international collaborators. |

requirements that could affect choice
of ship in scheduling. |
ADCP used to assess mooring drift. Radioisotope van requested for 14C preps. Cold van is requested for the incubation experiments. Coring equipment is requested for Mexinan collaborators.

Explain Major Ancillary Facilities
Requirements and list description
and provider for "other" systems. |
unsure of whether mooring spooler is required. Also, we may need a portable winch for deployment of floating moorings. Will discuss when scheduled. |
