QINGDAO - The Chinese scientific research ship Dayang Yihao, or Ocean One, is expected to set sail on a new global voyage on April 18, the country's oceanic authority said Friday.

The 380-day global trip will take the ship across the Atlantic and Indian oceans, said a spokesman with the Second Institute of Oceanography under the State Oceanic Administration.

The voyage, the 26th of its kind, will focus on research on polymetallic sulphides resources and biological resources in relevant areas, the spokesman said.

Dayang Yihao will carry advanced scientific instruments, including a remotely-operated underwater vehicle, he said.

It is not yet known how many scientists will participate in the scientific expedition, which will start from Sanya in South China's Hainan province.

On December 11 last year, Dayang Yihao completed a 369-day scientific research mission that covered more than 64,000 nautical miles, or about three times the length of the equator. The global trip took it across the Pacific, Atlantic and Indian oceans.
