Ice Patches
In the arctic, the ice patches are thinning and melting at an exceedingly rapid rate. When snow accumulates and doesn’t melt from the previous year, it creates these. An ice patch forms as the preserved layers accumulate. As a result, a layer of ice forms on the ground that is generally covered by snow, which prevents it from melting.
These patches are frequently frequented by wildlife. So, if they die, they may become solidified on the layer below them. Scientists are more often than not able to find information about these animals through the materials they leave behind. Tom Andrews was a trailblazer in the field of patch research. Their expeditions to Alaska and Canada’s Arctic regions were funded by him.
