I. Title ○ The development of the sea/drifting ice tracing technique using particle tracking model data II. Purpose and Necessity of R&D ○ Increased academic understanding of the distribution of Arctic sea ice / drift ice and changes in the marine environment ○ Rapid decrease of Arctic sea ice, unexpected distribution of sea ice, and increased fluidity of sea ice / drift ice require deep analysis and research on the movement route of sea ice / drift ice III. Contents and Extent of R&D ○ Developing a technique for tracking the movement path and origin associated with the particle tracking model by using the distribution characteristics of sea ice / drift ice detected in multi-satellite ○ Establish initial condition of particle tracking model for sea ice / drift ice and analyze tracking result of 2016 ○ Understanding of Arctic Ocean environment change using multi-satellite data IV. R&D Results - vi - ○ Analyze sea ice concentration, surface water temperature, and chlorophyll data from a global, regional, and integrated perspective to understand changes in the Arctic environment ○ Simulation and analysis of ice floe tracking using surface currents and wind field model data to predict the movement trajectory of floating ice on the surface of the summer Arctic Ocean V. Application Plans of R&D Results ○ Improved performance and accuracy through verification of particle tracking algorithm ○ Investigate the impact on the sea ice / drift ice path by rapid change in sea ice concentration ○ Continuous analysis and understanding of environmental changes in the Arctic Ocean
