China's self-developed underwater gliders have successfully conducted observations in the Indian Ocean, according to the Chinese Academy of Sciences (CAS).
Chinese oceanographic research ship Xiangyanghong 06 has returned to the city of Zhoushan in east China's Zhejiang Province on March 12, finishing a research expedition in the Indian Ocean. Developed by the Shenyang Institute of Automation under the CAS, 12 gliders codenamed Haiyi participated in this voyage as important survey equipment.
The 12 underwater gliders carried out cooperative observation in a designated sea area. Together they traveled more than 12,000 km and conducted more than 3,400 profiling observations, obtaining a large number of hydrological data including temperature, salinity, turbidity and oxygen content.
The mission of the 12 underwater gliders marks the application of indigenous gliders with the longest time and largest scale in Indian Ocean observation. It will promote the large-scale application of domestic marine equipment, according to the CAS. (Xinhua)
Chinese scientists have broken two world records this year at the ocean's lowest depth - the Mariana Trench. The trench is about 2,550 kilometers (1,580 miles) long and around 69 kilometers (43 miles) wide. It reaches a maximum-known depth of 10,994 meters (36,070 feet) – which is more than Mount Everest at 8,850 meters.
The Institute of Geology and Geophysics completed two 10,000-meter-deep marine artificial seismic profile data acquisitions with its Chinese-made Ocean Bottom Seismometers (OBS) at the bottom of the Mariana Trench on February 28, 2017, and China has become the world's first country to acquire 10,000-meter-deep marine artificial seismic profile data, Xinhua News Agency reported on Sunday.
