China’s ‘Xuelong 2’ begins first ice station survey in central Arctic Ocean_我的网站

Chinese research icebreaker Xuelong 2 arrives at the domestic base dock of China's polar expeditions in Waigaoqiao, Shanghai, on May 18, 2026. The vessel successfully completed all tasks of China's 42nd Antarctic expedition mission before returning to Shanghai.

After completing the first stage of comprehensive ocean station surveys on Friday, Xuelong 2 sailed toward higher latitudes and selected a large, relatively flat piece of sea ice about 1.5 meters thick in a densely packed ice zone for its first ice station. According to Lin Long, captain of the Xuelong 2 sea ice team, the ice station survey conducted by the vessel during this voyage will include six short-term ice stations and one long-term ice station, the Xinhua News Agency reported Sunday. More than 20 types of scientific operations will be carried out, including the deployment of expendable ice-based buoys, snow and ice-core sampling, under-ice water sampling, sea-ice remote sensing, atmospheric profiling and under-ice oceanographic observations. Lan Musheng, assistant to the chief scientist of the expedition, said the researchers will comprehensively monitor changes in parameters related to the atmosphere, sea ice, upper ocean and ecological processes beneath the ice as the sea ice melts. The observations will provide scientific data for studying the rapid changes in Arctic sea ice, the mechanisms behind those changes and the evolution of Arctic ecosystems. The ice station work is part of China's 16th Arctic Ocean scientific expedition, which was organized by the Ministry of Natural Resources. The expedition set sail from Dalian, Northeast China's Liaoning Province on July 3. The mission is being carried out by four vessels - Xuelong, Xuelong 2, Jidi and Tansuo-3 - and is expected to be completed in early October. The expedition is focusing on comprehensive surveys of sea ice, hydrology, biology, ecology and the atmospheric environment in key areas of the Arctic Ocean. The two icebreakers Xuelong and Xuelong 2 will work together on the ice station surveys. Xuelong completed surveys at 12 ice stations on Friday. Lin said the ice station locations planned for Xuelong 2 will work in coordination with those of Xuelong to form an observation array. The arrangement will allow researchers to more deeply investigate the interactions among the atmosphere, sea ice and ocean in the central Arctic Ocean amid rapid environmental changes, as well as their coupling effects with the ecosystem. The expedition is being conducted against a backdrop of rapid changes in the Arctic environment. When the mission was launched in July, expedition leader Wang Jinhui said that global warming was driving rapid and profound changes in the Arctic natural environment, with trends such as sea-ice melting intensifying. The expedition is therefore designed not only to monitor environmental changes but also to investigate frontier scientific questions, including the dynamic evolution of the oceanic crust. Working on sea ice also presents significant safety challenges. Low temperatures and complex ice-surface conditions can pose risks to researchers, while polar bears are considered the biggest safety risk during ice station operations. The expedition team has therefore formulated specific bear-prevention and emergency response plans and equipped personnel with various types of bear-deterrence equipment and emergency supplies to ensure their safety. 。
B | 在上周的讲话中，这一点得到强调，表示“坚定地致力于”抗击通胀。不过即便连续放缓，当前说通胀已经过了峰值还为时尚早，特别是考虑冬季能源价格会因为需求再次被推升，作为影响通胀的关键组成部分，很容易将物价再次推向新高。而在通胀公布前，隔夜美股市场因最新通胀预期连续放缓而获得提振，纽约联储的月度消费者预期调查显示，8月消费者认为未来12个月的通胀率料为5.75%，为2021年10月以来最低。消费者还预计未来三年的平均物价增幅为2.8%，为2020年底以来最低。
C | 美联储官员曾表示，控制通胀预期是确保通胀率在某个时候回落至2%目标的重要组成部分。旧金山联邦储备银行上周发布的一份研究报告称，美国家庭对未来通胀路径的预期越来越多地影响工资要求。美联储本月大概率加息75个基点，如果通胀连续放缓，但是放缓势头温和，将不足以改变美联储继续大幅加息的预期，所以今晚市场的波动视乎通胀最终结果和市场预期的出入，尤其是核心通胀的变化。如果通胀连续放缓，美债收益率预计跟随向下，美股向上寻求动力，继续刷新本月的高位。而美元昨晚已经先作调整，如果通胀降温超预期，美元可能进一步下探108，届时金价会获得更大动力延续反弹以1740美元上方为目标。返回搜狐，查看更多责任编辑：
