Zhang-Jian

Sept. 23 (Xinhua) -- The Chinese deep-sea research ship Zhang Jian returned to her home port in Shanghai after finishing a 74-day scientific research trip to the Southern Pacific. The vessel is the mothership for the Rainbow Fish, a manned submersible capable of diving to 11,000 meters. During its 9,000 nautical-mile maiden voyage, the research vessel travelled across the South China Sea and the Pacific Ocean to reach the New Britain Trench, which is more than 8,000 meters-deep in the Solomon Sea near Papua New Guinea. Chinese scientists onboard the vessel carried out joint ocean environmental research with their counterparts in Papua New Guinea. Captain Zha Dawu said the vessel went through several typhoons, including Meranti and Malaka, and an earthquake, during the journey, which tested the ship's navigation performance and research facilities.
