Chinese seventh Arctic scientific expedition team successfully completed the task expedition Beijing, Xinhua news agency, "Snow Dragon" in September 16, review: China seventh Arctic scientific expedition team successfully completed the task expedition Xinhua News Agency reporter Wu Yue China seventh Arctic scientific expedition, complete the expedition mission, aboard the "Snow Dragon ship left back. From July 18th arrived at the first operation stations, the team completed a total of 84 comprehensive marine work station in 54 days, including the completion of 59 stations operating in the Arctic Ocean region, the north to latitude 82 degrees 53 minutes. According to reports, the investigation involves a number of physical oceanography, marine meteorology, marine geology, marine chemistry and marine biology, the expedition mainly on the Arctic ice, sea, air, melting pool and biological samples of 5 elements, observation and research. Investigation team chief scientist Li Yuansheng said, regardless of the number of tasks or this expedition expedition equipment level belong to our previous Arctic expedition of the. The sea ice buoy array quest ablation Arctic expedition not less natural sea ice research. "Snow Dragon" ship into the Arctic circle after the inspection team found that the expected large area of ice covered sea scene did not come to the party, even at 75 degrees north latitude near the high latitude area, around the hull still small and thin ice, sometimes there will be large open water area. This is a true portrayal of the rapid melting of sea ice in the arctic. Affected by this, the team in the near 79 degrees latitude was selected for the first piece of ice ice station operations, the latitude and the previous expedition compared to north. Lei Ruibo, chief scientist of the expedition, said Arctic sea ice ablation will have a direct impact on China’s climate. The results show that the Arctic sea ice reduction and our winter precipitation increase is directly related to, or even bring cold, rain and other weather disasters in china. To understand the variation of sea ice in the Arctic expedition, a total of 40 base cloth ice buoys, including the use of helicopters, cloth buoy array composed of 13 buoys placed in the Canada Basin on the ice, this is the rules of the buoy array our previous Arctic expedition construction. These buoys will move along with the sea ice, and will continue to record the movement of the sea ice in the next two years. Lei Ruibo said that as the ice drift, the buoy into the Arctic core region, to further expand the area of China’s Arctic expedition. At the same time, continue to send back buoy data can make China’s Arctic expedition data collection from summer to winter, to provide important scientific data for the study of Arctic sea ice changes quickly, improve our ability to predict the future climate change in the Arctic Ocean, sea ice changes and environmental changes. Communication and navigation technology to ascertain the Arctic by using acoustic acoustic observation of water power development, acoustic communication, navigation technology is an important topic in the underwater polar Arctic expedition. The investigation team work period a total of two ice underwater acoustic observation experiment. Every time by the "launcher Snow Dragon Ship on the high frequency radio signal receiving device receives the signal, set up the drilling expedition in ice station,.相关的主题文章:
