Data on large scale change in sea ice and resulting impacts.   For example: “walrus depend on sea ice as a platform for giving birth, nursing, and resting between dives to the seafloor, where they feed. In recent years, when summer sea ice in the Chukchi Sea retreated over waters that were too deep for walrus to feed, large numbers of walrus abandoned the ice and came ashore. The high concentration of animals results in increased competition for food and can lead to stampedes when animals are startled, resulting in trampling of calves.”
