Arctic sea ice is projected to thin and reduce in extent significantly over the next century. Both sea ice and its overlying snow limit the amount of light that reaches the upper ocean, impacting the phenology of ocean primary productivity. Recent studies using in-situ data and pan-Arctic satellite observations emphasize the influence of current trends in sea ice and snow on the timing of under-ice, or ice residing algal blooms. This analysis is extended here using Climate Model Intercomparis...
