摘要:
真光层在海洋初级生产力估算，全球碳循环，甚至全球气候变化研究中有重要意义。传统的测量方法非常耗时，也无法大面积同步观测，而遥感技术的发展为真光层的计算提供了大尺度观测的新方法。黄海和渤海作为与我们活动最为密切的边缘海，其真光层研究更为重要。本文尝试依据真光层反演机理模式，利用SeaWiFS气候态月平均Kd (490)数据，反演出黄渤海的真光层气候态月分布，并简单分析其空间分布原因。Euphotic Zone Depth (Zeu) plays an important role in studying the ocean primary production, global carbon cycling, or even global warming. The traditional methods may be easy to operate, but needs much time, and cannot measure at large scale. The remote sensing technology is a new tool to observe Zeu at large scale. Bohai sea and Yellow Sea are marginal seas which affect our daily life greatly, so the research of their Zeu is rather important to us. Based on radiation transfer mechanism, this paper uses SeaWiFS climatory Kd (490) monthly data to analyze the spa-tial-temporal characteristics of Zeu over Yellow Sea and Bohai Sea.
