| 1. Cruise code : |
|
|
2. Main research theme: |
| Temporal biogeochemical changes in the western North
Pacific and adjacent seas |
|
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 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) |
RMS water sampling and analysis of salinity, oxygen,
nutrients, CFCs, total alkalinity, DIC, DOC, and pH. |
| 3) |
RMS water sampling for dimethylsulfide, phytoplankton
pigments and heterotrophic bacterial production. |
| 4) |
Underway measurements of pCO2, DIC, temperature, salinity
and nutrients. |
|
5. Main research area: |
The western North Pacific:35 - 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, area out of the EEZ of Russia
including the eastern Bering Sea. |
