长江口科学考察实验研究

Focusing on the scientific questions, the opening scientific cruise will becarried out by R/V "Ke Xue San Hao" in the Yangtze River Estuary in spring and autumn. Based on multidisciplinary investigations including physical ocenaography, marine geology, marine biology, and marine chemistry, we seed to acquire regional samples and records of long-term environmental changes in order to reveal the transportation processes of various substances and responsive mechanisms of the ecological and environmental effects in the Yangtze River estuary and the neighbouring sea area. This will accumulate elemental data and advance the fundamental marine sciences and integrated marine managements, exerts the greatest potentials of the present resources andfacilities, and enhance our intensive study of the regional ocean phenomena.

利用"科学三号"科学考察船，聚焦长江口海区的科学问题，在春季、秋季各组织具有公益性、基础性、战略性的海洋科学考察共享航次，以河口和陆架边缘海海洋环境演变和生态系统响应为主线，通过物理海洋、海洋地质、海洋生物和海洋化学等多学科的综合调查研.究，获取长周期的区域海洋样品和环境参数变化记录，以期揭示长江口及邻近海域的物质输运过程及其生态与环境效应的的响应过程和机理，积累基础资料，最大限度地发挥现有资源的潜能，加强对该区域海洋现象的深入了解。

2013年基金委长江口开放航次分为两个航次执行，冬季航次于3月3日-3月21日执行，搭载15个项目，完成14条断面，89个站位，1个连续站；夏季航次于8月15日-8月26号，共完成14条调查断面，68个调查站位，1个连续站。
