| 摘要: |
| 应用2007年1月和7月国家908专项北黄海区块水体调查获取的浊度等资料, 分析了夏季和冬季北黄海海域水体浊度的水平和垂向分布特征, 初步阐述了夏、冬季北黄海水体浊度分布具有南北高, 中间低的特征。无论是夏季还是冬季, 山东半岛东北沿岸和辽东半岛东南沿岸为高浊度区, 中部海域受北黄海冷水团的影响而维持低浊度。夏季, 北黄海冷水团导致的水体层结效应产生了“水障”作用——悬浮物只能沿岸分布和输送; 冬季, 山东半岛东端外海的强海流切变锋阻碍了悬浮物的纬向输送。此外, 研究还发现由于黄海冷水团和黄海暖流的作用, 导致夏、冬季黄海中部的沉积动力环境有所差异。 |

| WATER TURBIDITY IN THE NORTHERN YELLOW SEA IN SUMMER AND WINTER |

| Abstract: |
| Using temperature, turbidity, and concentration of suspended matter observed in summer and winter in our national project National Coastal Sea Comprehensive Investigation and Evaluation in the northern Yellow Sea (No. 908-ST02), horizontal and vertical water turbidity distributions in summer and winter were analyzed. Results show that high turbidity was in the north and south of the northern Yellow Sea, and low in the middle of the northern Yellow Sea in summer and winter, persistently. High turbidity was found along the Shandong Peninsula and Liaodong Peninsula and low turbidity in the middle of the northern Yellow Sea in both seasons. In summer, the northern Yellow Sea Cold Water Mass prevented the suspended matter along coast to the north and east of Shandong Peninsula from transporting eastwards; and in winter, a shear front generated by upwind compensation current along peninsula prevented the latitudinal transportation of suspended matter. Moreover, the interaction of the Yellow Sea Cold Water Mass and the Yellow Sea Warm Current resulted in different sedimentary environments in the central part of the northern Yellow Sea. |
