| 1. Cruise code : |
|
|
2. Main research theme: |
| Studies on Arctic Ocean circulation linked to Arctic
climate system |
|
3. Objectives: |
| The overarching goal is to prepare for global change
and to reduce uncertainties in forecasting, a substantial improvement in
our fundamental understanding of processes controlling variability in
Arctic climate systems; specifically: of shelf/basic interactions; and
inter-basin forcing of ice and water properties of land/ocean exchanges.
This cruise mainly focuses on the "water mass circulation" which
establishes proper condition for ice cover. Key water masses are Pacific
Winter and Summer Waters, Atlantic Mackenzie and Siberian River Waters,
and Melt Waters. |
|
4. Outline of observation: |
| - |
CTD and water samplings |
| - |
Underway observations (XCTD, ADCP) |
| - |
Mooring deployment and recovery |
| - |
Multi-beam sonar |
|
5.
Main research area: |
| Arctic Ocean (Beaufort Sea, Chukchi Sea, Canada
Basin)(exclude the Russian EEZ) |
|
6. Ports of call: |
Port of Departure : Dutch Harbor
(Arctic Ocean)
Returning port : Dutch Harbor |
|
7. Cruise period: |
31 August 2004 - 11 October 2004(42 days)
The actual duration of field experiments north of the Bering Strait:
3 September 2004 - 8 October 2004 (36 days) |

10. Notes |
| (1) |
36 bottles with 12 L Rossete sampler is
scheduled to be used. Basically, one cast at one station is planned. |
| (2) |
We hope participations of geochemical teams
who focus on water mass circulation and mixing. |
| (3) |
Ice condition strongly influences the
schedule of the cruise. |
| (4) |
Basically no science station is planned in
the Bering Sea except underway observations. |
