Evaluation of Sea Ice Kinematics and their Impact on Ice Thickness Distribution in the Arctic
Sea ice area and thickness have been on the decline in the Arctic over the past several decades. Understanding the role of ice motion, deformation, and export is important to determining if the Arctic will continue toward seasonal ice coverage or if natural variability is capable of reversing this t...
