2. Main research theme : |
A study on the heat and material transports and their
variability of the general ocean circulation
A study on chemical environment and its changes in the ocean |
|
3. Objectives : |
It is well known that the oceans play a central role
in determining global climate. However heat and material transports
in the ocean and their temporal changes have not yet been sufficiently
quantified. Therefore the global climate change is not understood satisfactorily.
The purposes of this research are to evaluate heat and material transports
in the North Pacific and to detect its long term changes and basin-scale
biogeochemical changes since the 1990s.
Forming in the North Atlantic Ocean and the Southern Ocean, the deep
water flows in the deep circulation and consequently arrives in the
North Pacific. It has been known that the deep water in the north Pacific
is mainly supplied from the South Pacific through the Wake Island Passage.
The main purpose of this research cruise is to evaluate material and
heat transports of the deep ocean water through the Wake Island Passage. |

Measurements of temperature, salinity, oxygen and current
from surface to bottom using CTD/O2 with LADCP |
| - |
Water sampling using RMS (Salinity, Oxygen, Nutrients,
CFCs, Total CO2, Total Alkalinity, pH etc.) |
| - |
Underway measurements (Shipborn ADCP, Bathymetry,
Meteorological measurements etc.) |
| - |
Recovery of moorings (CTD, Temperature/Depth recorder,
Current meter and ADCP etc.) |
|
