摘要
应用2007月7月国家908专项北黄海区块水体调查获取的浊度资料,与同步获得的悬浮物质量浓度进行拟合分析,结果表明,中底层水的相关系数在0.94以上,表层相关度较差。根据调查海域浊度的水平大面分布及选取的6个典型断面的垂直分布,初步阐述了夏季北黄海水体浊度的分布特征——近岸高和底层高,山东半岛北部沿岸、成山角海域和老铁山水道以及庄河河口附近海域为高浊度区。夏季北黄海冷水团对水体浊度分布具有控制性影响:调查海域水体垂向层结稳定,北黄海冷水团海域中下层表现为高盐、低温、高密特征,水体浊度小,且浊度锋面的分布与温度较为相近。同时,夏季北黄海冷水团对悬浮物的分布起到了屏障作用——在山东半岛北部沿岸和辽东半岛南部沿岸阻止了近岸悬浮物的经向输送,而在山东半岛东部沿岸则阻止了近岸悬浮物的纬向输送。
Distribution of water turbidity in the northern Yellow Sea in summer is characterized of high concentration in the bottom layer and the nearshore water, for example, along the northern Shandong Pe- nisula, Chenshan Cape, Laotieshan water channel and around the Zhuang River estuary. The northern Yellow Sea Cold Water Mass （NYSCWM） played an important role in the distribution of water turbidity. Water was stratified in the NYSCWM area, with high salinity, low temperature and high density in the bottom layer. Water turbidity also exhibited low value in the YSCWM area. Furthermore, locations of water turbidity front and temperature front were close. This indicated that, the NYSCWM could prevent the latitudinal transport of suspended sediment from the shallow water in the east of Shandong Peninsula and longitudinal transport from the southern water of Liaodong Penisula and from the northern area of Shandong Penisula to the south.
