Following the requirements of basic scientific problems for the designs and safety operations of ice-breaking or operation ice-resistance ships in ice covered areas in future Arctic navigation, the ice physical and mechanical properties are necessary. The sea ice physical and mechanical behavior at different positions in Arctic will be investigated. The relationships between ice internal physical and mechanical properties and external meteorological and hydrological conditions will be set up. The feasibility and accurate of the evaluation of the ice physical and mechanical behavior from satellite productions and data will be performed. The spatial and temporal distributions of Arctic sea ice physical and mechanical parameters are mapped and the services for the ship designs and ship safety operations will be searched based on the achievements mentioned above. For these purposes, the applied project will use the obtained sea ice physical and mechanical property data from the 5th China Arctic Expedition in 2012, and will collect more data in the 6 th and 7th China Arctic expeditions in 2014 and 2016. The methodology from Bohai sea ice mechanical propeties with Bohai meteorological and hydrological conditions will be used. From the collaborations with international and domestic institutes/universities, we will set up the "connection" for using satellite data or productions to obtain the area sea ice sheet physcial and mechanical parameters and will finish the mathematical methods to express the spatial and temporal distributions of the ice sheet physical and machanical properties. These results will be used to support the safety navigations in Arctic ice covered area in future.
