The Snow Dragon Polar Survey
The Xue long is China's largest polar expedition ship and the only vessel in China that can break ice in the polar regions. The ship is cold resistant and can break through 1.2 meters of ice at a 1.5 knots speed (containing 0.2 meters of snow).
In August 16th 2017, China's 8th Arctic scientific expedition completed its last CTD sampling operation in the Arctic Ocean's high seas area, and the "Snow Dragon" vessel sailed into the Norwegian Fisheries Reserve. Heading to the waters of the Ross Sea at 78 degrees 41'S. This is the highest latitude the Snow Dragon has reached in the Southern Hemisphere, It also set a new record for the most southern reaches of the global scientific research vessel in the Antarctic Sea. Meanwhile, this is the first time that the Chinese expedition team has successfully crossed the central waterway of the Arctic Ocean and started operations in the sea area. In September 23rd 2017, the Snow Dragon successfully completed its first exploration of the Arctic Ocean around China. A total of 7 sea ice stations and 49 ocean stations were carried out, and a multidisciplinary comprehensive survey focusing on marine basic environment, sea ice, biodiversity and marine plastic litter was carried out, and abundant ice cores were collected. The core and biological samples obtained a large amount of atmospheric, sea ice, ocean observation data and image data, which contributed to the construction of the "Silk Road on Ice".
