Activity: Cruise Implementation
 

MOMSEI veered to its implementation phase from 2010, which was clearly reflected by the following activities.

Progress on the Cruise Implementation
With the significant contribution from partners from Thailand, Indonesia and China, three are three (3) cruises implemented during May 2010 and May 2012.

• First MOMSEI Cruise
The first MOMSEI cruise was carried out in Andaman Sea in 20-23 Oct. 2010, with main contribution from Phuket Marine Biological Center (PMBC) of Thailand and First Institute of Oceanography (FIO) of China. PMBC provided the ship time, the package of the oceanic observation for the cruise while FIO provided the package of atmospheric observation.

The multidiscipline measurements were carried out during the cruise. The scope of observation is summarized in Tab.1 and Tab.2.

The second MOMSEI cruise was carried out in Andaman Sea in 11-17 Mar. 2011, with main contribution from Phuket Marine Biological Center (PMBC) of Thailand and First Institute of Oceanography (FIO) of China. PMBC provided the ship time, the package of the oceanic observation for the cruise while FIO provided the package of atmospheric observation. The multidiscipline measurements were carried out during the cruise. The scope of observation is summarized in Tab.3 and Tab.4.

• Third MOMSEI Cruise
The third MOMSEI cruise was the first MOMSEI endeavor in the eastern tropical Indian Ocean and also the longest cruise MOMSEI ever had, which was carried out in Andaman Sea during 20 Apr. and 12 May, 2012, with the main contribution from Agency of Marine and Fishery Research (AMFR) of Indonesia and First Institute of Oceanography (FIO) of China. AMFR arranged its R/V MADIDIHANG for the cruise, which is equipped with full atmospheric and oceanic instruments. FIO provided the GPS soundings. The multidiscipline measurements were carried out during the cruise. The scope of observation is summarized in Tab.5 and Tab.6.
