      ANTARCTICA-CHINA-ROSS SEA-RESEARCH STATION

      Photo taken on Feb. 7, 2018 shows temporary buildings of China's fifth research station in the Antarctic on Inexpressible Island in Terra Nova Bay in the Ross Sea. Chinese researchers have selected the site for the station and laid a foundation. The Ross Sea is a deep bay in the Southern Ocean regarded as the least altered marine ecosystem on earth -- a living laboratory that could possibly tell the life history of the Antarctic. China has built four Antarctic research stations over 30 years of research, with Changcheng and Zhongshan serving as the two perennial stations, and Taishan and Kunlun being the two summer stations.
