【摘要】 2007–2009年通过搭载黄海冷水团航次及中国近海开放共享航次共4个航次，在黄海利用CTD获得了154个站位的经纬度、水深、底层水温度和盐度数据；通过154个站位的沉积物样品的采集和分析，获得了调查站位沉积物的粒度、含水量、有机质含量、叶绿素a及脱镁叶绿素a含量以及各参数分层分布情况。针对原始观测数据和实验室分析的数据，数据质量控制过程包括对原始观测数据的检查整理、单个数据的检查、数据的整编。黄海底层水CTD观测及沉积环境因子数据集的建立，给研究海洋底栖环境和底栖生态系统的长期变化提供了基础资料。更多还原

【Abstract】 Four cruises were conducted in the Yellow Sea from 2007 to 2009. Through conductivity-temperature-depth(CTD) observation, the study obtained data on the water depth, bottom water temperature and salinity of the Yellow Sea from 154 stations. Then based on sample collection and analysis using a 0.1-m2 modified Grey-O’Hara box corer, we measured the sediment median grain size, as well as the horizontal and vertical distribution of sediment water content, organic matter, chlorophyll a and pheophytin a. The dataset of CTD and sediment environmental parameters will aid in better understanding the long-term changes of the benthic environment and ecosystem in the Yellow Sea.更多还原
