| 摘 要： | 2000年6月至2002年6月春夏季期间,在南黄海春夏季南黄海西部沿岸低盐水入侵温跃层现象的研究鱼产卵场进行了4个航次的多学科调查,海洋水文观测分析结果表明:在苏北浅滩外侧、成山头—石岛外侧的层化海区的温跃层中存在低盐水现象.春夏增温季节温跃层加强,低盐水入侵现象逐渐增强;入侵强度也存在年际变化.苏北浅滩入侵低盐水舌向北偏东方向延伸,水舌较宽,入侵较远;石岛附近入侵低盐水舌向南偏西方向延伸,水舌较窄,入侵较弱.温跃层中低盐水是由于沿岸低盐水入侵造成的,并与当地的潮锋现象存在密切的关系.

| Abstract: | Based on the 4 synthetic cruise CTD data in the period of spring and summer from June 2000 to June 2002,it is revealed that there exists intrusion phenomena of low salinity water (LSW) in the region of stratification outside the northern Jiangsu Shoal(NJS) and nearshore around Chengshantou-Shidao (CS).The LSW intrudes much wide and strong as long as the stratification strength and varies with the years.The tongue like LSW intrudes northeastward and southwestward respectively from NJS and CS.The former is wide and strong,while the latter is relatively weak.The LSW is caused by the intrusion of the fresh coastal water and has a close relationship with the distinguished tidal front in that area. |
