2. Main research theme: |
| Tropical Ocean Climate Studies |
|
3. Objectives: |
| For the purpose of understanding the role of the warm
water pool related to El Nino and Asian Monsoon, which affect the social
and economical activities in the East Asian countries including Japan,
we will conduct the observational studies on the oceanic and atmospheric
variability. The main purpose is to clarify the heat, water budget and
momentum balances in the surface mixed layer in the warm water pool in
the western Pacific Ocean as well as the eastern Indian Ocean. The data
also is utilized to reveal the interaction between the Pacific Ocean
and the Indian Ocean through exchange of heat and fresh water by the
Indonesian Throughflow. |
|
4. Outline of observation: |
| The principle purpose of the cruise is to obtain the
physical parameters on the ocean and the atmosphere. During the former
half of the cruise, the major works are to recover and to deploy surface
moored TRITON buoys and subsurface moored ADCP buoys. The three TRITON
buoys will be recovered and deployed along 130E, and the four ones will
be along 137E (or 138E). The two buoys will be recovered and deployed
also in the eastern Indian Ocean. CTD measurements up to 1000 m depth
(Leg1) or 2000m depth (Leg 2) will be carried out around the buoy deployment
area with water sampling by twelve 12-litter bottles. |
