Why do everyone go to Antarctica for inspection and exploration? Why not go to the North Pole?

For those who also went to the Arctic, the record of China’s ninth Arctic scientific expedition (5) The North was hit by domestic fires. At the end of July 2018, the news that some areas of the Arctic Circle were experiencing rare high temperatures went global. Hot search. According to reports, a rare high temperature of 30 degrees Celsius occurred in the polar circle in northern Sweden, and in northern Siberia, the temperature once reached 32 degrees Celsius. During the same period in previous years, the average temperature in this area was only 10 degrees Celsius. This extreme high temperature weather is demonstrating that Arctic climate change is showing a more complex trend. Although far away from the motherland, China's ninth Arctic scientific expedition team still learned the news from domestic media. Unlike the heat in some areas of the Arctic Circle, the expedition team traveling in the Arctic Ocean still feels the coldness. The abnormal climate made the team members more deeply aware of the necessity of Arctic scientific expeditions. At 4 a.m. on August 1, the temperature in the Chukchi Sea dropped below zero degrees Celsius, and the scientific expedition team members working on the back deck of the "Snow Dragon" even had runny noses from the cold. Even if they occasionally walk on the deck, the team members are fully armed. The wind from the Arctic Ocean blows, and everyone can't help but wrap up their cotton clothes. Since entering the ice area, the "Snow Dragon" ship will make a few muffled "clang" sounds from time to time, followed by a violent turbulence, and then continue to break through the ice. In the past few days since entering the ice floe area, the temperature has remained between minus 4 degrees Celsius and 0 degrees Celsius. Judging from the temperature and ice conditions, the Arctic Ocean expedition area is the same as in previous years, with no obvious abnormalities. It can be seen that the extreme weather processes in the Arctic Circle mainly occur in the Nordic region and have no direct impact on the northwest ice ocean area where the scientific expedition team is located. The Arctic is an important source of cold air in my country. The formation process of Arctic sea ice regulates the strength of the East Asian winter monsoon and is an important factor affecting my country's climate. Therefore, studying Arctic climate change is not only an important topic for scientists around the world, but also has important guiding significance for predicting climate change in my country and the development and utilization of Arctic waterways. The rapid change of Arctic climate is an environmental and climate issue that humans face and are concerned about. Since the 1990s, my country has begun exploring the Arctic and has carried out nine Arctic expeditions, providing a data basis for studying changes in the atmosphere, sea ice and oceans. Since China’s eighth Arctic scientific expedition in 2017, my country has started pilot work on operational observations for the first time. During the "Eight North" campaign, two sets of anchored submersible buoys were deployed and a year-long marine environment observation data was obtained, which can support our country's research on rapid climate and environmental changes in the Arctic region to a certain extent. However, the observation and survey foundation is still weak and is still in its infancy. The Arctic climate system is complex and changeable. Just observing and surveying one sea area or one or two stations in one year is not enough, and it is difficult to achieve scientific research purposes. Therefore, carrying out ocean and climate observations in the Arctic region, especially long-term regular surveys, is both basic and very necessary work. China's ninth Arctic scientific expedition further expanded the scope of operational monitoring/monitoring work, and for the first time combined operational monitoring/monitoring work with scientific research projects to promote each other and jointly serve the purpose of climate and environmental change in the Arctic region. Research. To better carry out scientific expeditions in the Arctic region, strengthening international cooperation is necessary. This time, the expedition team will cooperate with the Mossek International Drift Ice Station plan in preliminary preparations, provide valuable observation data, and make my country's due contribution to this plan. Although our country has made certain progress in research on Arctic climate and environmental changes, it can only be regarded as the first step. Looking to the future, if an optimized and complete long-term continuous observation/monitoring network can be established in the Arctic region, we can more specifically monitor the climate change situation in the region and provide a higher level of prediction and response to climate change. scientific support.
