中国第15次北冰洋科学考察返航

Core Insights - The successful completion of China's 15th Arctic scientific expedition by the "Snow Dragon 2" ship marks a significant achievement in understanding the rapidly changing Arctic environment and its implications for global climate change [1][2] Group 1: Expedition Overview - The expedition involved four vessels: "Snow Dragon 2," "Polar," "Deep Sea One," and "Explorer Three," making it China's largest Arctic scientific investigation [1] - The mission was organized by the Ministry of Natural Resources and aimed to implement national key research and development plans [1] Group 2: Scientific Achievements - Collaborative operations between "Snow Dragon 2" and "Polar" enhanced synchronous observation capabilities in high-latitude Arctic regions, filling data gaps and supporting marine environmental forecasting [2] - Long-term monitoring of ice drift and underwater ecological changes provided insights into seasonal variations and underlying mechanisms in the Arctic [2] - The deployment of multiple underwater biological imaging systems at various depths yielded extensive data on the ice edge zone, contributing to the understanding of the "sea-snow" formation mechanism and the ecological responses to sea ice retreat [2] Group 3: Deep-Sea Exploration - The "Deep Sea One" ship, supported by "Snow Dragon 2," successfully conducted China's first manned deep-sea dive in the Arctic ice zone, indicating advancements in deep-sea exploration capabilities [2] - Preliminary studies revealed significant spatial variations in benthic organism density, diversity, and size across Arctic seabed areas, aiding in the assessment of climate change impacts on deep-sea ecosystems [2]
