中新社上海9月28日电 题：与海沟深渊"较劲"：中国青年科研工作者闯入"无人地" 作者 谢梦圆 "我们相信这些微生物可以在地球之外的极端环境中生存。所以它们也许能改变外星环境，帮助我们重 塑家园。"赵维殳说。 这些研究成果突破了该领域在国际上40年的瓶颈，从采样规模到数据分析能力，中国已实现从"跟跑"到 部分"领跑"的跨越。回顾科研历程，赵维殳将科研者分为"三代"，从她上一代的白手起家、压力重重， 到她下一代的机遇无限，她感受到每个科研工作者都充满干劲，"我们指导的'00后'研究生们下潜上来 后，都说还没看够"。 同样充满活力的还有研发海空连续穿越技术的"哪吒"科研团队。哪吒团队指导老师、上海交通大学研究 员曾铮将团队名称定为"哪吒"，正是希望团队成员能学习哪吒百折不挠的韧性。 这支团队的科研工作者平均年龄约30岁，专注于研发海空跨域无人航行器，使其能在空中飞行、水面航 行、水下潜航之间自如切换。研发的产品在国内外同类成果中，下潜深度最大、负载能力最强、海况适 应范围最广。 若将珠穆朗玛峰塞进马里亚纳海沟，峰顶仍会淹没在水下2000米。当一个泡沫塑料杯被带入这11000米 深渊，会承受约1100个大气压(相当 ...

Group 1 - The Canadian military and possibly the coast guard are closely monitoring the Chinese research vessel "Xuelong 2," which has appeared in the Arctic waters near Alaska for the second consecutive year [1][2] - A CP-140 reconnaissance aircraft from the Canadian Air Force was reported to be flying near "Xuelong 2" as it left the Bering Strait on the 20th of this month, although the Canadian Department of National Defence did not confirm the aircraft's presence [1] - The Canadian military stated that they will continue necessary activities to detect, deter, and defend against potential threats within and near Canadian territory, emphasizing that "Xuelong 2" is not currently in Canadian territorial waters [1] Group 2 - The Canadian Coast Guard was reported to have been following "Xuelong 2" until it crossed the Bering Strait, but initially provided vague responses regarding their mission [2] - The Coast Guard later denied monitoring "Xuelong 2," claiming their focus was on the migration routes of key species like Pacific salmon, despite data showing only one-third of the vessel's recent journey aligned with known salmon migration paths [2] - An expert from Beijing Foreign Studies University noted that Canada seems reluctant to disclose details about the incident, suggesting that the monitoring activities are essentially harassment of civilian vessels, and emphasized that China's research activities comply with international maritime law [2]

Core Points - The third United Nations Ocean Conference commenced on June 9 in Nice, France, focusing on promoting ocean protection and the implementation of Sustainable Development Goal 14 [1][3] - A key objective of the conference is to push for the ratification of the agreement on the conservation and sustainable use of marine biodiversity in areas beyond national jurisdiction, which requires approval from 60 countries to become binding international law [3][5] - The conference highlights the urgent need for funding to support Sustainable Development Goal 14, which is currently one of the least funded goals [5][7] Group 1 - The conference agenda includes discussions on the challenges facing ocean protection, emphasizing the relationship between climate action, ocean health, and biodiversity loss [3][4] - French President Macron and other leaders stressed the importance of basing discussions on scientific evidence rather than subjective opinions, expressing strong support for marine research [3][4] - The U.S. National Oceanic and Atmospheric Administration has faced significant cuts under the previous administration, raising concerns about the impact on marine research and multilateral cooperation [4] Group 2 - The conference includes a Blue Economy and Finance Forum aimed at addressing financing for ocean protection, with discussions on raising funds through financial institutions, private investments, and blue bonds [7][8] - The final declaration, known as the "Nice Ocean Action Plan," will address key issues such as funding, fishing practices, and deep-sea exploration [8] - The international community is urged to unite in addressing these challenges to restore the vibrant and diverse oceans of the past, as highlighted by UN Secretary-General Guterres [8]
