Core Viewpoint - China's 42nd Antarctic Expedition is currently underway, with the "Snow Dragon" conducting ocean operations in the Amundsen Sea, completing 8 survey stations and planning over 20 stations in total during the expedition [1] Group 1: Ocean Operations - The "Snow Dragon" is engaged in various tasks including the deployment of temperature, salinity, and depth instruments, as well as krill and mid-water fish trawling [1] - The successful recovery of a biological buoy deployed during the 41st Antarctic Expedition demonstrates the expedition's capabilities in polar research [10] Group 2: Buoy Recovery Process - The recovery of the buoy involved navigating to a location 4 kilometers from its coordinates, where a cable was deployed to release the buoy from its anchor [2][4] - After multiple attempts, a drone successfully retrieved the buoy's cable, but the complete recovery of the buoy, which is over 3000 meters long and equipped with multiple observation devices, took over six hours [6][8] Group 3: Buoy Deployment Process - Following the recovery, a new buoy was successfully deployed in the same location, marking three consecutive years of buoy deployment by the Antarctic research team [11] - The deployment process required collective effort, with team members coordinating to manage the long cable and ensure proper placement of the buoy [13][14] Group 4: Challenges and Conditions - The deployment and recovery operations were conducted in challenging conditions, including cold temperatures and the presence of drifting ice, which required careful monitoring [16][20] - The team experienced a sense of accomplishment despite the harsh weather, as they successfully completed the buoy deployment after over two hours of outdoor work [20]
