Chinese research vessel "Kexue" concluded a 74-day-long scientific exploration in the Western Pacific Ocean, the longest voyage in its history.
The ship docked in the city of Qingdao in east China's Shandong Province on Thursday after completing a voyage of more than 12,000 nautical miles.
While carrying out investigation in the core area of the Western Pacific Warm Pool, scientists of physics, biology and chemistry conducted joint observations of the Central Pacific where the warm pool and the cold tongue meet. It was their first joint observation in the area.
Meanwhile, scientists successfully transmitted data through the homemade Beidou satellite system at the depth of 6,000 meters under water.
"The most outstanding breakthrough of this voyage is that we realized ocean data live transmission through our homegrown satellites, changing the history when we could only rely on foreign satellite for data transmission. Meanwhile, the depth at which we transmitted data has been expanded from 1,000 meters, 3,000 meters to the current 6,000 meters under the surface. It means that we can track the changes in marine environment from the sea surface to 6,000 meters under water," said Wang Fan, director of the Institute of Oceanology under the Chinese Academy of Sciences.
Chinese scientists have placed over 1,000 sets of equipment including 20 deep-sea buoys and four large buoys at the Western Pacific, which enable them to obtain observation data from the upper to the mid and low layers of the ocean for four to five consecutive years.
