     |  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. |  |

        | - | CTD and water samplings |   
        | - | Underway observations (XCTD, ADCP) |   
        | - | Mooring deployment and recovery |   
        | - | Multi-beam sonar |  | 
     
     |  5. Main research area:

         the Russian EEZ) |  |

 | 
    
     | 
        
        | (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. |  |
