极区海洋锚碇观测系统的设计和布放

THE DESIGN AND DEPLOYMENT OF MOORING SYSTEM IN POLAR REGION

中国第2次北极科学考察(2003年7月—9月)期间,在白令海峡和北冰洋楚科奇海布放了一套潜标和两套明标,在该次考察结束前成功回收了潜标和1套明标,获得了最长为45天的连续观测资料。通过介绍这次布放过程,对极区锚碇系统的相关技术问题进行了讨论,包括观测站位和层次的选择,锚碇系统的设计、布放步骤等,为有海冰存在的低温海域布放锚碇系统提供参考。

During the Second Chinese National Arctic Research Expedition in 2003, 3 mooring systems were deployed in the Bering Sea Strait and Chuckchi Sea of the Arctic Ocean. One was submerged totally and the other two had floating balls at surface. Before the expedition was finished, the submerged mooring and one mooring with floating balls were successfully recovered. Continuous data about 45 days were obtained. By introducing the design and deployment process, the technology questions related with mooring system in polar region are discussed. Selection of observing stations and layers, design of mooring system and the steps of deployment are presented in this paper, which will give the references to deploy anchorage system in the low temperature and ice-covered ocean.
