摘要:叶绿素a是植物光合作用中的重要光合色素。海水中的叶绿素a浓度是浮游植物现存量的重要指标,可以表征水域初级生产者的聚碳能力。海水中的叶绿素a浓度数据一直是海洋生态系统研究的基础数据,也是海域生物资源评估的重要依据。胶州湾是我国海洋生态系统研究的重点模式海湾,其生物区系结构具有南黄海的特征。山东胶州湾海洋生态系统国家野外科学观测研究站(简称胶州湾站)对胶州湾内定位监测站长期进行气象、物理、化学、生物等多项指标进行测定。本数据集基于胶州湾站对12个定位监测站长期叶绿素a测定数据整理形成。整理过程采用中国国家生态系统观测研究网络(CERN)统一规范的数据处理方法和质量控制体系对原始数据进行质量控制和整理、加工。同时对时间序列数据进行3sigma检验结合临近站点时间序列对比进行异常值剔除,统一插补后形成数据表格,同时提供长时间序列图共享下载,满足不同用户的需求。本数据可以用于海湾生态健康评估、初级生产力长期变化、海湾生态系统演变、水色遥感等科学研究,也为政府有效制定环境质量限值和防治措施提供数据支撑。

Abstract & Keywords
Abstract: Chlorophyll a is an important photosynthetic pigment in plant photosynthesis. Concentration of chlorophyll a in seawater is an important indicator of phytoplankton stocks, which can represent the carbon accumulation capacity of primary producers. The data of chlorophyll a concentration in seawater is always the basic data for the study of marine ecosystem research and important for the assessment of marine biological resources. The Jiaozhou bay is the model bay in the focus of marine ecological environment research in China. The phytoplankton structure of Jiaozhou bay is similar to that of the south yellow sea. The meteorological, physical, chemical, biological and other indicators in Jiaozhou bay have been monitoring for a long time by the Jiaozhou Bay National Marine Ecosystem Research Station, Shandong (the Jiaozhou Bay Station). The dataset is based on the long-term chlorophyll a observation data of 12 fixed station in the Jiaozhou bay from 1997 to 2010 by the Jiaozhou Bay Station. The original data of dataset adopts the Chinese Ecosystem Research Network of Chinese Academy of Sciences (CERN) standardized quality control system and data processing method. Data were removed which failed by 3sigma test combined with the time series comparison of adjacent sites. To meet the needs of different users, the dataset is processed after interpolation and long-time sequence diagrams are made for sharing service on line. The dataset can be used for scientific research on gulf ecological health assessment, long-term change of primary productivity, evolution of gulf ecosystem, remote sensing of water color, etc., and also provide data support for the government to set environmental quality limits effectively and prevention and control measures.
