由国家海洋局海洋环境保护研究所和大连化学工业公司联合进行的碱渣海洋倾倒实验于1989年6月20日至7月4日在北黄海Ⅴ号倾废区进行。 6月24日,Ⅴ号倾废区海面风平浪静,“中国海监”19号船驶向预定位置,烟渔拖1号拖轮拖着烟渔驳1号载着250t白色碱渣,缓缓驶向倾废中心,三点零五分,一声令下,满船碱渣倾入海中,海面立刻显现出一片浅兰色的“云团”,逐渐扩展,随着潮流漂散。 “中国海监”19号海洋水文、化学工作者利用多种先进仪器停机滑行穿过“云团”,并对“云团”进行扫描跟踪,监视记录碱渣的扩散范围和扩散速度; “中国海监”20号船立刻驶向倾废中心
The experiment of oceanic dumping of caustic soda carried out jointly by the Institute of Marine Environmental Protection of the State Oceanic Administration and Dalian Chemical Industry Co., Ltd. was carried out in the dumping area of North Huanghai Ⅴ from June 20 to July 4, 1989. On June 24, No. V dumping area was calm on the sea and No. 19 ship of “China Marine Surveillance” was heading for a scheduled position. The No. 1 tugboat towed by Yan Yuyou No. 1 carrying 250t white caustic soda slowly drifted toward Dumping center, three o’clock five minutes, the order, the full ship caustic soda into the sea, the sea immediately showed a light blue “cloud”, and gradually expanded, with the trend of drift. Marine hydrologists and chemists at No. 19 China Marine Surveillance and Monitoring Center used a variety of advanced equipment to stop and glide through the “cloud” and track the “cloud” and monitor and monitor the spread and diffusion rate of the residue. “China Sea monitor ”20 boat immediately toward the dumping center
