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。
The National Oceans and Coastal Information Management System (OCIMS) of South Africa is a large, integrated IT system for enhancing oceans, coastal and maritime governance, and supporting sustainable...
Due to lack of regional data constraints, all global ocean tide models are not accuracy enough in offshore areas around China, also the displacements predicted by different models are not consistency....
In general, image mosaicking is a useful and important processing for handling images with narrow field of view. It is being used widely for images from commercial cameras as well as from aerial and s...
Kien Giang is one of the coastal provinces in the Mekong Delta which is facing the problem of coastal erosion to affect people’s life in the coastal area. This project aims to monitor shoreline and to...
The article gives a brief description of the system of space monitoring of high water and floods. Its main tasks are the operational dynamics of snow and ice cover melting and the passage of flood wat...
Sea level rise causes devastating effects on coastal habitats. For example, coastal erosion and saltwater intrusion are major threats for the Black Sea coasts. So, determining sea level changes in the...
The measurements of UV spectral irradiance, ozone and aerosol load obtained with a double monochromator Brewer at the Station for Climate Observations of the National Agency for New Technology, Energ...
Perhaps the most popular oceanographic setting for the public is the beach and nearshore environment. Poetic accounts since early history describe the comings and goings of tides, waves and sand. More...
Spatially adaptive sampling is necessary to resolve evolving gradients with sparsely distributed sensors. Assessing the reality of numerical model fields with ever increasing resolution, testing dynam...
T-phases are acoustic signals in which the primary portion of the propagation path is through tile oceans. Energy sources resulting m the generation of T-phases include earthquakes, submarine volcanis...
The Straits of Florida is a trough that separates the Florida Peninsula from Cuba and the Great Bahama Bank (Figure 1). It acts as both a conduit and a barrier for ecosystem exchange and is an i...
