China's 41st Antarctic expedition team set sail from New Zealand for the Ross Sea, embarking on a joint research mission to conduct scientific investigations of the Antarctic in autumn. After completing resupply and crew rotation in mid-March at New Zealand's Lyttelt on Harbor in Christchurch, the team aboard China's research icebreaker Xuelong 2, or Snow Dragon 2, officially launched the Ross Sea joint expedition. It is China's first research autumn mission in the Antarctic sea, with Chinese and international scientists working together to explore the ecosystem of the deep bay off the Antarctic coast.
