第42次南极考察 “雪龙”号大洋队开始大洋考察作业

Core Viewpoint - The Chinese 42nd Antarctic Expedition, led by the "Snow Dragon" vessel, is conducting significant oceanographic research in the Amundsen Sea, focusing on marine ecosystem elements and the impacts of climate change [1][2]. Group 1: Expedition Overview - The "Snow Dragon" vessel's ocean team consists of 31 members from 12 domestic research institutions and universities [1]. - The expedition aims to conduct a comprehensive oceanographic survey in the Amundsen Sea and adjacent waters from mid-January to mid-February 2026 [1]. - The research will enhance understanding of the ecological characteristics of the target marine area and track changes in key species populations [1]. Group 2: Research Focus and Methodology - The expedition will investigate critical elements of the marine ecosystem, including hydrology, meteorology, biology, and chemistry, to gather data on the Southern Ocean's ecological status [1]. - New technologies, such as ecological mooring arrays and domestic unmanned detection equipment, will be employed to support the comprehensive survey [2]. - Continuous observations since 2018 have been crucial for capturing the complex and rapid changes in the marine environment of the Amundsen Sea [2]. Group 3: Climate Change Impact - The Amundsen Sea region is significantly affected by global climate change, with notable melting of ice caps and ice shelves [1]. - This area is a focal point for international Antarctic research concerning climate change, making the findings from this expedition particularly valuable [1].
