Science-1 Accomplished Its Voyage with Satisfying Research Data


Science-1 came to the land.

The Science-1 of IOCAS fulfilled its research journey and returned triumphantly on August 4th. The staff on board were given warmly welcome from the academician Dunxin Hu, the deputy director Tiegang Li, the assistant director Fan Wang as well as some scientists and students of IOCAS. 

Science-1 sailed out to the western Pacific to do some observations and collect data from early July 2011, covering more than 7000 nautical miles during 31 days, completing 11 research tasks of national funds, 973 and 863 projects and with 42 scientists and 4 institutes involved. The researchers have retrieved two subsurface moorings deployed at the depth of 6100m and 3400m last year and deployed three more in the western Pacific. This is the first mooring successfully deployed and retrieved at the depth of 6000 or so in this waters of China, and prominently, it is also internationally first to obtain the data featured long period and direct observation at the 8°and 18°N, Western Boundary Currents. These precious data will be very useful for the Northwestern Pacific Ocean Circulation and Climate Experiment (NPOCE), the international cooperative program mainly initiated by Chinese scientists.


The scientists are deploying floats.

During the one month sailing, the underwater glider developed and manufactured by China on its own feet also made a successful debut in this scientific expedition, which terminated the western monoply of the underwater glider technology in China.

The scientific staff on board depending on their rich experience and wisdom overcame great difficulties probably caused by typhoon, and spotted and observed a pair of mesoscale eddies in the sea east of Taiwan, which bring us the invaluable data on temperature, salinity, velocity and other features of mesoscale eddy structure variation in Kuroshio current region.

This scientific expedition has collected lots of useful and precious data conducive for future oceanological study. Following the investigation to the northwestern Pacific at the beginning of 2011 and under the joint efforts from the scientists on board as well as constant concerns from other scientists in the institute, this significant event undoubtedly promotes the oceanic study in western Pacific actively and efficiently.
