| 1. Cruise Code : |
|
|
2. Main research theme : |
| Biogeochemical cycles in the western North Pacific |
|
3. Objectives : |
| Temporal biogeochemical changes in the ocean have to
be clarified for evaluation of the global warming and the prediction.
The objectives of this research cruise are to understanding
biogeochemical cycle using sediment traps, to evaluate biogeochemical
changes along 155 degree East in the North Pacific, to characterize
chemical properties along the Kuril Islands and the western
Bering Sea, and to elucidate the biogenic gas flux through the
air-sea interface in the northern North Pacific. |
|
4. Outline of observation : |
| 1) |
Measurements of temperature, salinity and oxygen
profiles using CTD/O2. |
| 2) |
Recovery and deploying of sediment traps and
others. |
| 3) |
RMS water sampling and analysis of salinity,
oxygen, nutrients, CFCs, total alkalinity, DIC, DOC, pH and
other chemical components. |
| 4) |
RMS water sampling for primary production measurement. |
| 5) |
Underway measurements of pCO2, DIC, temperature,
salinity and nutrients. |
|
5.Main research area : |
The western North Pacific: 30 - 44°N,
155°E, the Kuril Islands and the western Bering Sea. Observations
in the EEZ of Russia will be done under agreement of Russia.
When such agreement cannot be obtained, observation area is
out of the EEZ of Russia. |
