Improved Canadian Arctic Sea Ice Thickness Estimates

Communities in the Canadian Arctic depend on the sea ice for traditional hunting and harvesting activities. The presence of sea ice also protects coastal communities from waves during storms. The loss of sea ice however is impacting stability of the ice, making travel across sea ice less predictable and more dangerous, and coastal communities are more at risk to storm surges. Ecosystems that depend on the ice area also changing rapidly, with still unknown impacts on ocean primary productivity, while polar bears, seals and whales are having to find new habits. As sea ice continues to decline, it is imperative to better understand the drivers of current and future sea ice changes so that we can improve our ability to forecast ice conditions at various time-scales, from near-real-time for safe marine navigation, to seasonal and decadal for planning purposes.
