Core Viewpoint - The article highlights the significant advancements and contributions of Dalian University of Technology in polar ice research, showcasing the journey of researchers like Lu Peng and the importance of their work in understanding climate change and its effects on polar regions [8][20]. Group 1: Historical Context and Development - The study of sea ice in China began after a severe ice disaster in the Bohai Sea in 1969, which prompted the establishment of research initiatives at Dalian University of Technology [10]. - Dalian University of Technology has developed a comprehensive system for sea ice observation, forecasting, and structural design to ensure safety against ice-related challenges [10][20]. - The university's research has evolved from local studies in the Bohai Sea to significant contributions in polar regions, including participation in multiple Antarctic and Arctic expeditions [14][15]. Group 2: Research Contributions and Innovations - The university has accumulated extensive data from over 30 polar expeditions, leading to the development of critical observational tools for polar research [15][21]. - Innovations include the creation of the ICE-SDEM software for simulating ice loads on structures, which has been integrated into national standards for polar equipment design [21]. - The research conducted has implications for global climate change understanding, regional climate regulation, and the development of polar shipping routes [20][21]. Group 3: Current and Future Endeavors - The upcoming expedition of the "Zhongshan University Polar" icebreaker in 2025 will further enhance China's capabilities in polar research, with Lu Peng leading the ice station team [16][19]. - The research team aims to collect data on ice thickness and environmental conditions, contributing to models that assess sea ice growth and melting [17][18]. - The findings from these expeditions are crucial for addressing the challenges posed by climate change and for informing future engineering and environmental strategies [20][22].

Core Viewpoint - The Chinese 41st Antarctic Expedition Team has successfully conducted its first autumn-winter voyage in the Ross Sea, focusing on ice research and yielding preliminary findings in marine biology and chemistry [1][7][17]. Group 1: Expedition Overview - The "Snow Dragon 2" icebreaker returned to China after completing its mission in the Ross Sea, where the team explored various forms of sea ice and their significance [1][2]. - The expedition provided a rare opportunity to observe the entire formation process of sea ice, which is typically difficult to encounter in previous Antarctic studies [4][6]. Group 2: Scientific Discoveries - The team conducted research across 24 selected stations, exceeding the initial plan of 18, covering shallow areas, ice-interstitial lakes, and rich krill resource zones [8][15]. - Significant findings include a decrease in the biomass of certain marine species, particularly the absence of brown algae and a decline in diatom populations, indicating potential ecological shifts [10][12]. - The discovery of a large number of zooplankton in deep water layers suggests changes in their distribution due to deep convection processes [12][13]. Group 3: Implications and Contributions - The expedition not only advanced scientific knowledge but also improved operational processes for Antarctic autumn oceanic work, enhancing the capabilities of the research team [15][17]. - The results contribute to a better understanding of the Antarctic ecosystem and fill gaps in field observations and experiments, aiding in the global understanding of climate change impacts [17].

Core Viewpoint - The article discusses the first autumn-winter joint scientific expedition in the Ross Sea, Antarctica, focusing on the deployment of various types of buoys to study the interactions between sea ice, ocean currents, and waves. Group 1: Scientific Objectives - The buoys deployed are designed to measure the acceleration and movement of ice, as well as the relationship between ice and waves, with the aim of studying the atmospheric and oceanic processes affecting ice formation throughout the winter [3][5]. - The new type of lotus leaf ice buoy is being deployed for the first time, intended to collect data on the different stages of ice development throughout the season, particularly during the ice growth season [10]. Group 2: Types of Buoys Deployed - Five types of buoys are being deployed, including surface drift buoys, ice-drifting buoys, and wave-ice buoys, which will monitor surface water flow rates, ice movement, and interactions with waves [12][14]. - The lotus leaf ice buoy will provide positional information and will be tracked via satellite to understand the dynamics of ice development [10]. Group 3: Environmental Impact - Sea ice plays a crucial role in the Earth's energy balance by reflecting solar radiation back into space, which helps mitigate warming in polar regions [14]. - Sea ice acts as a natural barrier between the atmosphere and ocean, regulating heat exchange and influencing ocean circulation and the global climate system [14].
