China's first manned deep-sea submersible returned to Shanghai on Wednesday after a two-month voyage that included filming marine life at a depth of 1,500 meters (almost 5,000 ft.)
The Jiaolong, which entered service in 2010, dived a record 7,062 meters in the Pacific's Mariana Trench in June 2012.
Traveling aboard its carrier, the Xiangyanghong 09, the research craft entered the Yangtze River estuary Wednesday, China's official Xinhua news agency said.
The 10 scientists who manned the Jiaolong for this mission collected 390 creatures from the sea floor, including coral, sea cucumbers and sea anemones.
"It is a significant issue in China's oceanic study," Wang Pinxian, an academician at the Chinese Academy of Sciences, said. "It is quite important to get first-hand materials for deep-sea study." EFE
