| Outline of Final Research Achievements |
Time-series data of sea-ice thickness have been accumulated for eight years by the mooring observation conducted in the coastal region off northern Alaska. We revealed that large yearly variability in ice thickness is caused by variability in sea-ice drift pattern associated with local winds.
Based on time-series oceanic data, we showed that the generation and maintenance of the coastal polynya in this region are governed by not only offshore sea-ice drift but upwelled warm subsurface water, and winter water formed in this region is influenced by not only Pacific-origin water but also Atlantic-origin water.
