Sixth Arctic survey operations in full swing in China | | expedition _ China News
Xinhuanet,, July 19 (reporter Xu 硙)-"Snow Dragon" scientific research ship, 18th to the Bering Sea coast, started this tour's first stop is the observation and sampling, it also marked the sixth Chinese Arctic expedition work in full swing.
Day of the expedition team will be weighed more than 200 kilos of "CTD" observation system is lowered into the sea for the relevant work.
"CTD" observing system is used to measure sea temperature and salinity (electrical conductivity), automatic recording instrument of pressure, dissolved oxygen from 24 adoption of a 10-litre water bottles and some test instrumentation. Each down to a certain depth, seawater samples collected water bottles will be collected automatically. Laboratory on board computer also receives and displays the observed marine data in real time.
In this job, "CTD" sank to more than 3,000 square meters under the sea, turbulence observed in-situ filter, sea 150 metres with a large volume water operations have been carried out. After 3 hours, this time to complete.
In the next 10 days or so, scientific expedition team will also be 36 stations along survey in the Bering Sea, marine, chemistry, biology, geology, hydrology, atmospheric and other aspects of the comprehensive observations and sampling. During this period, deploying air-sea flux of 1 set of anchorage buoy.
According to the expedition's Chief Scientist, introduced pan zengdi, Bering Sea region was China's Arctic expedition focused on waters, one of the top five expeditions, has accumulated a large amount of data. The screens of choices to consider not only the repetition, but also the international hot scientific issues.
The Bering Sea is located in the northern most region of the Pacific Ocean between Asia and North America, the Strait's narrowest point is only more than 80 square kilometers. Pacific Ocean through the Bering Sea into the Arctic water, accounting for about 10% all the water of the Arctic Ocean. Pan zengdi said: "the energy and matter Exchange in the Bering Sea, have direct effects on environmental change in the Arctic, is an important basis for study of climatic and environmental change in the Arctic. ”
The Chinese Arctic expedition has set general hydrologic station 82, which are located in regions of the Bering Sea and the Chukchi Sea and the Canada basin area. Also set 17 mobile stations in the Pacific sector of the Arctic Ocean, located in the High Arctic waters, work will be completed based on the ice conditions and distance in time such.
