摘要
颗粒有机碳(POC)是海洋碳循环研究的一个重要参数,采用水色遥感技术反演颗粒有机碳浓度为大时空尺度监测海洋碳循环过程提供了重要手段。从基础数据采集入手,简要总结了当前颗粒有机碳样品采样方法及误差影响因素;针对颗粒有机碳水色遥感的国内外研究进展进行了综述,深入分析了POC与生物光学参数之间的关系,对在此基础上建立起来的多种POC水色反演算法进行了归纳和分类比较;简要总结了POC水色反演在多时空尺度监测海洋生态环境中的应用。最后指出了我国海区POC水色遥感研究还存在的问题,对今后的研究工作进行了展望。
Particulate organic carbon（POC） is an important variable in studying carbon cycle in the ocean.Ocean-color remote sensing of POC provides a useful means for monitoring the variation of carbon cycle on a large scale.This paper is a review on the progress of ocean-color retrieval of POC from satellite data at home and abroad.A brief introduction was given first about sample collecting methods of POC and error analysis.Bio-optical relationships between POC and optical properties were then described in detail.Present ocean-color algorithms for retrieving POC were categorized and compared,and their applications in detecting multi-scale variability of marine ecosystem were summarized.Research perspectives on future study of POC retrieval from ocean color in China were proposed at last.
