日本核污染水排海给经济复苏添堵
日本 核污染水 海洋环境 经济复苏
2023/8/7
日本政府强推核污染水排海是对民意的无视，也是对自身责任的推脱。海洋污染等环境问题既是事关人类健康的安全问题也是经济问题。日本强排核污染水入海不仅将严重打击本国水产业等关联行业，也将给全球经济带来隐忧。
2023年1月11日，由中国科学院大气物理研究所牵头，联合国家海洋环境预报中心、中国科学院海洋研究所等全球16个研究单位的24位科学家组成的国际研究团队，在《ADVANCES IN ATMOSPHERIC SCIENCES》（AAS）发布了涵盖2022整年的全球海洋环境（温度和热含量、盐度、层结）变化研究报告。新的研究指出：2022年海洋升温持续——成为有现代海洋观测记录以来海洋最暖的一年。同时，...
自19世纪末首次使用水银温度计来测量海水温度开始，过去百余年间，人类通过使用不同的测量仪器，收集了总计超过1600多万条海洋温度观测廓线。海量的观测数据已经广泛用于涉及海洋、海气、气候变化等相关研究和科学政策制定当中。然而，由于海洋现场观测数据的测量手段多样、数据错情类型繁多，导致了数据质量千差万别。如何高效、快速、自动化地识别错误数据并对其进行质量控制（Quality Control, QC）仍...
海洋热含量变化是全球气候变化的一个核心指标，也是链接地球系统能量循环、水循环和碳循环的一个关键点（图1a）。近些年，随着热含量观测数据集不断丰富，探究海洋热含量变化事实、机制并揭示其气候影响，逐渐成为海洋和气候变化研究领域的热点和焦点问题。同时，大量研究也产生了一些争议之处，亟需进行较为系统的梳理。
