Abstract:

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.
