Outline of Main Research Theme for Research Vessel “MIRAI”
during fiscal year 2006

1. Cruise Code :
MR06-05 Leg-3

2. Main research theme :
Tropical Ocean Climate Study

3. Objectives :
For the better understanding of El Nino and Asian Monsoon, which affect the social and economical activities in the East Asia counties including Japan, we will conduct the observational studies on the oceanic and atmospheric variability from intraseasonal to interannual time scales in the warm water pool region of the Pacific Ocean. We aim to elucidate the surface mixed layer process and interhemisphere water exchange, which may control the climate system in the region.

4. Outline of observation :
The main missions are to recover and to deploy TRITON surface moorings. The four TRITON moorings will be recovered and deployed along 137E (or 138E), and the two ones will be along 130E. CTD and XCTD measurements will be carried out around the mooring sites.

5. Main research area :
8N-139E, 1S-139E, 2N-126E, 8N-126E
(TRITON mooring sites are 137E-8N, 5N; 138E-2N, Eq; 130E-8N, 2N)

6. Cruise period :
From mid-December, 2006 through mid-January, 2007 (30 days)

7. Ports of call (tentative):
Port of departure: Singapore
Returning port: Sekinehama, Japan
