翟惟东，男，化学海洋学家。主要从事海洋碳化学及生源要素的生物地球化学研究，发表论文和图书章节80余篇，其中SCI收录的期刊论文60多篇，H指数30。主持完成国家自然科学基金青年基金和面上项目共4项，以及国家重点基础研究发展计划（973计划）课题、原国家海洋局海-气CO₂通量评价方法项目、海洋公益性行业专项子任务和山东省自然科学基金面上项目各1项。现主持国家重点研发专项课题1项，参加国家自然科学基金碳中和专项项目1项。在边缘海碳源碳汇计量、调控机制分析，以及高CO₂环境的生态效应（海洋酸化）评估方面取得了系统性研究成果：发展了碳氧耦合分析方法以揭示珠江口高CO₂维持机制(Zhai et al., 2005a)；提出依据生物地球化学分区定量估算南海CO₂通量的研究思路(Zhai et al., 2013)，明确南海主体海域为大气CO₂的弱源区(Zhai et al., 2005b; 2013; 翟惟东, 2015)；参与提出黑潮中层水侵入南海之后上涌维持碳源作用的过程机制(Dai et al., 2013, GRL)；深入研究了长江口无机碳输出通量及其河口生物地球化学过程(Zhai et al., 2007; 2014a; 2017; Xiong et al., 2019)，发现并阐明长江口外海域在秋季由于水柱分层被破坏，导致底层水中积累的无机碳上涌，从而向大气释放CO₂成为碳源的现象(Zhai and Dai, 2009)；发现渤海正在出现局部缺氧现象(Zhai et al., 2012; 2019)，被纳入世界自然保护联盟(IUCN)的《海洋脱氧》报告（2019年），揭示出渤海富营养化加剧的海洋环流因素(Zheng et al., 2020)；而黄海则因中高纬度冬季海-气再平衡吸收CO₂与夏秋季高强度生物代谢活动相叠加而出现季节性酸化的现象(Zhai et al., 2014b; 2015; Zhai, 2018; Li et al., 2022)，建立酸化指标与钙化过程生态效应之间的关系(Li and Zhai, 2019)，揭示出年度初始值对浅海季节性跃层以下的海洋酸化指标动态变化的深刻影响(Xiong et al., 2020; Li and Zhai, 2021; Yu et al., 2022)。获得2009年度高等学校科学研究优秀成果奖自然科学奖一等奖（第2完成人）和2019年度浙江省科学技术进步一等奖（第5完成人）各一项。

Prof. Zhai works on marine carbon cycling study since 2000. His research areas include air-sea exchange fluxes of carbon dioxide and other green-house gases, biogeochemical coupling between carbon dioxide and dissolved oxygen, and nutrient dynamics in aquatic environments. Most recently, his research focuses on the responses of coastal ocean carbon cycle and ecosystem to a changing terrestrial export of carbon and nutrients as well as hypoxia and coastal acidification in China seas and Chinese estuaries.
