| 1. Cruise code : |
|
|
2. Main research theme: |
| Time-series observational study on the Material Cycle
in the North Pacific |
|
3. Objectives: |
| The northern North Pacific, especially its western part,
has been attracting attention of chemical oceanographers because of its
importance in global biogeochemical cycles of carbon and its related
materials, which have a great impact to the climate change of the earth.
In addition, physical oceanographers have been interested in that region
with respect to the formation of the North Pacific Intermediate Water.
Despite its importance, there has been few systematic survey and time-series
observation of biogeochemical processes in the area to estimate the impact
of high latitude seas on the global climate change. |
|
4. Outline of observation: |
| Based on the above mentioned goal, time-series observational
stations including station K1 (51N, 165E), K2 (47N, 160E) and K3 (39N,
160E) were set. During cruise, time-series observational mooring systems
will be recovered and deployed. In addition, seawater, aerosol, suspended
materials and plankton will be collected at above stations, KNOT and
so on. Vertical profiles of salinity and temperature will be measured
by XBT and XCTD. |
