| 摘 要： | 利用2013年秋季和2014年春季两个季节黄渤海现场数据对黄色物质的水平分布及垂向分布的变化进行研究,并初步分析了其主要控制因素。垂向黄色物质表现为底部高上层低的特征。其中,秋季混合作用加强导致上层40m黄色物质混合较为均匀;春季北黄海温盐跃层已经形成,黄色物质分布开始出现明显的分层现象,上下层浓度差约为2?g/L。春季南黄海盐度跃层尚未形成,水深小于50m的水层黄色物质垂向分布均匀,近岸和远岸海域浓度分界线明显。水平方向上,黄色物质在秋季和春季分布趋势一致,由渤海、北黄海至南黄海浓度依次降低,且呈现出由近岸向中央海区递减的趋势,但整体上春季浓度较秋季明显偏低。海表盐度与黄色物质浓度两者整体上呈现负相关关系,可以将黄色物质浓度分布作为研究黄海暖流走向、划分水团性质的重要指标。

| Abstract: | We studied the spatial distribution of yellow substance in the Yellow Sea and Bohai Sea and analyzed the main controlling mechanism, based on data collected in autumn 2013 and spring 2014. High concentration of yellow substance occurred in the lower layer and near-shore area, while low concentration in the upper layer and off-shore area. In autumn, yellow substance distributed evenly in the areas of <40m in depth due to strong water mixing. In spring, thermocline and halocline formed in the North Yellow Sea and the distribution of yellow substance was stratified obviously in concentration difference between upper and lower layers. Halocline was not formed in the South Yellow Sea when yellow substance well distributed in the depth of <50m. The distribution pattern at sea surface is similar in autumn and in spring in a descending order of Bohai Sea, North Yellow Sea, and South Yellow Sea, showing a decreasing trend off the coast. However, the overall concentration in spring is clearly lower than that in autumn. Yellow substance concentration showed a negative correlation to salinity in the sea surface. Therefore, yellow substance in seawater reflects important information for understanding the ocean current direction and water mass distribution in the Yellow Sea. |
