Antarctic sea ice plays crucial roles in the global climate and polar ecosystems, including: 1) regulating moisture and heat flux by forming an insulating layer between ocean and atmosphere; 2) modulating surface energy budget through ice-albedo modification (i.e., sea ice has higher albedo so reflects more solar energy than the ocean); 3) modifying near-surface ocean physical properties via ice production and melting processes; and 4) providing a habitat for polar primary production and higher level fauna (e.g., penguins and seals). To advance our fundamental understanding of Antarctic sea ice, baseline knowledge of Antarctic sea ice physical properties (i.e., ice concentration and thickness) and ice kinematic processes (i.e., ice motion and deformation) is essential. Observations of sea ice motion from satellites and buoy arrays have been widely and repeatedly used for the past four decades to investigate ice properties and kinematics in both Arctic and Antarctic, however there exist many gaps in sea ice ...
