TRANSPORT PROCESS OF POLLUTANTS IN THE SOUTHERN YELLOW SEA

叶绿素a、浊度和卤代碳的研究是1997年8月在南黄海和东中国海域进行的，该海域是水柱植物生产力较高的区域。采样点为29ﾟN~30ﾟn两个断面的11个采样点，采样点最大深度为16号站长98m至11号站位1159m，每个站位6个水深的采样器装有12个容量为1.5 1的尼斯金样品瓶(General Ocean)。CTD系统还配备了氧气传感器和现场荧光仪(Aquatracka，切尔西环境仪器)。在1997年陆架至陆架边缘调查期间，128.00ﾟE西部陆架内陆架的叶绿素a浓度较高，盐度相对较低。结合1995年和1997年的叶绿素和浊度数据，表明长江口丰富的营养盐和颗粒物质向海洋输送。研究了东中国海卤素浓度的分布，以评价这个水柱中植物生产力相对较高的海洋区是一个天然的卤碳源。在1997年8月期间，检测到水中含有高浓度的卤代烃。卤代烃的分布和相互关系表明，东中国海海水中存在一定的卤代烃来源。

The research for chlorophyll a, turbidity and halocarbon was carried out during the cruise conducted on board the research vessel Shinyo Maru during August, 1997 in the Southern Yellow Sea and East China Sea area that exhibits relatively high plant productivity in the water column. The sampling sites were 11 stations along 2 sections between 29ﾟN and 30ﾟ N.The maximum depths of sampling stations were from 98 m at Sta.16 to 1159m at Sta.11.Water samples were collected fron 6 depths at each station with a CTD-rosette sampler fitted with 12 Niskin sample bottles of 1.5 1 volume (General Oceanics). The CTD system was also equipped with a oxygen sensor and in situ fluorometer (Aquatracka, Chelsea Environmental Instruments). During 1997 survey at the region from the shelf to the shelf edge, the higher chlorophyll a concentration which had relatively low salinity in the continental coastal water was observed on the inner shelf of western part of 128.00ﾟ E.By combining the 1995 and 1997 chlorophyll and turbidty data, suggesting the the seaward transport of rich nutrients and particles from the Changjiang River estuary develop.Distribution of halocarbon concentrations in the East China Sea was examined to evaluate this oceanic area, with relatively high plant productivity in the water column, as a natural halocarbon source. The high concentrations of halocarbons in water were detected during August 1997. Both distributions of halocarbons and correlations among halocarbons showed that there was some sources of halocarbons of seawater in the East China Sea.
