China's research vessel Kexue moves across the Taiwan Strait, Jan. 10, 2015. China's most sophisticated research vessel -- named Kexue, or Science -- left from the eastern city of Xiamen last Saturday on a new expedition to a west Pacific seamount. The second expedition to the Yap Seamount sea area will focus on deep-sea environment and ecology. With 74 people on board, the vessel is expected to travel 6,000 nautical miles and return in mid-February. (Xinhua/Meng Jing)
