China News Service, Beijing, September 28 (Reporter Ruan Yulin) China’s Ministry of Natural Resources reported on the 28th that the China’s 12th Arctic Science Expedition Team took the "Snow Dragon 2" on the 28th after a 79-day test of wind and waves and a total voyage of 14,000 nautical miles. The ship returned to the dock of the domestic base in Shanghai, marking the successful completion of China's 12th Arctic scientific expedition.
China’s 12th Arctic Scientific Expedition, organized by the Ministry of Natural Resources, set sail from Shanghai on July 12. It was the first Arctic scientific expedition organized by China during the "14th Five-Year Plan" period.
According to reports, this scientific expedition focused on responding to climate change and protecting the Arctic ecological environment. It adopted navigational observations and cross-sectional surveys in the Arctic high seas to successfully complete the comprehensive observations of the Chukchi Sea atmosphere, ocean, and ecology, and obtained a number of results. Scientific research results.
This inspection is also China's first self-built polar scientific expedition icebreaker "Xuelong 2", and it is the second time to undertake the Arctic scientific expedition.
On July 15, 2020, "Xuelong 2" embarked on China's 11th Arctic Scientific Expedition from Shanghai and embarked on its first Arctic scientific expedition trip.
The Arctic is one of the important areas for the exchange of materials and energy between the atmosphere and the ocean, and it plays an important role in the formation and changes of the global atmospheric climate system.
The exchange process of energy and matter between the atmosphere and the ocean mainly occurs at the sea-air and sea-ice-air interfaces.
The study of sea-ice-air energy and material exchange is of great significance to correctly understand the role of the Arctic region in global climate and environmental changes and to improve China’s weather, climate and natural disaster forecasting.
