The results of drift bottle and drift card experiments in the Bohai Sea and Huanghai Sea obtained by researchers of the Institute of Oceanology, Academia Sinica from 1975-1980 are reported in this article. Of over 50,000 bottles and cards released, around 10,000 were recovered.The results gave some convincing evidences for the existence of the Huanghai Sea Coastal Current, theHuanghai Sea Warm Current, the cyclonic movement around the northern Huanghai Sea Cold Water Mass,the anticyclonic eddy in the area near the Shidao-Qingdao coast and the flow of some of the Huanghai Seawater to the Japan Sea and to the North Pacific off Tokyo. The results show that the drift bottles and cardsare still useful for getting the flow pattern of enclosed and semi-enclosed seas. 相似文献

随着我国经济建设的蓬勃发展，工农业和城市生活产生的污染物日益增多。如何处理这些污染物成了一个急待解决的问题。将污染物化有毒为无毒，当然是最彻底的办法，但这样做花费巨大，我们目前尚难做到。目前最常用的办法是将污染物排放人海。但过多的排放，超过了海洋的自净能力，就会污染海洋环境和海洋资源，进而影响人民的健康。所以，须要对污染物排放人海的方式、地点等加以选择，并对其排放人海的数量、速率等加以控制。这就要求我们了解海区对污染物的净化能力和在国家规定的标准下海区对污染物的最大容量。为了很好地解决这个问题，我们必须了解特定海区对污染物的稀释扩散起重要作用的海水运动情况。1984年5, 8, 10三个月，我们在渤海湾海河口区进行了海上调查，并结合历史资料，以COD 为指示因子，进行了渤海湾有机污染物在潮流作用下稀释扩散的数值计算。 相似文献
