Summary of Field Work: |
The field work includes the recovery of 9 current meter moorings and the deployment of 10 moorings on the Bering Sea shelf. The moorings are deployed along the 55, 40, and 25 meter isobaths. In addition, we will occupy about 80 CTD stations along the mooring lines, with ~30 of these including water sampling for nutrients and oxygen isotopes. The number of CTD stations will be determined based on the pace of the mooring work and the cruise track. We will also use the ship's vessel-mounted ADCP system and underway seachest sampling. |
|
Summary of Facility Requirements: |
We request 10 science days. The mooring operations will require use of the vessel A-frame and crane. Other shipboard facilties needed are the CTD and Rosette sampler (5 liter Niskins suffice). Usually no more than 5 bottles will be tripped per cast. We require the shipboard ADCP and seachest sampling systems while underway. |
|
Summary of other requirements and comments: |
We expect 6 - 7 science personnel. |

Dates to Avoid: |
We are conducting mooring operations in the northern Bering Sea (Nunivak Island to St. Lawrence Is.) Operations in May are likely to occur in ice. Scientific personnel have scheduling problems beginning in August. |

Requested Start Port |
Intermediate Port(s) |
Requested End Port |
|
Seward, AK, USA |
Dutch Harbor, AK, USA |
Dutch Harbor, AK, USA |
Explanation/justification for requested
ports and dates of intermediate stops
or to list additional port stops |
The cruise can begin in either Seward or Dutch Harbor. From the scientists point of view the mooring gear is more easily loaded in Seward (where the moorings are assembled) at the University of Alaska's dock than in Dutch Harbor where the moorings would have to be barged and stored. However, we are flexible in terms of the loading port. |
