Outline of Final Research Achievements

The pan-Arctic high-resolution sea ice-ocean modeling studies were conducted to examine subsurface warm water transport under sea ice in the southern Canada Basin. The interannual experiment for 2001‐2014 reproduced mid-winter or spring warming signals which were observed by subsurface hydrographic sensors in the Chukchi Borderland. The modeling analyses indicated that he Barrow Canyon throughflow and the westward jet along the Chukchi shelf break reasonably accounted for lateral ocean heat transport and consequent subsurface warming in the downstream regions. It was also suggested that highly stratified condition due to anomalous sea ice meltwater assisted the winter heat transport.
