| 1. Cruise Code : |
|
|
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. |
|
4. Outline of observation : |
-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.
