Crewed and uncrewed aircraft used for polar climate research has expanded in recent years. Sensors have been deployed onto the surface (e.g., buoys, profilers, motion sensors). Aircraft allow remote sensing and human observing of surface temperature, salinity, ocean and glacier elevations, wave state, mixed layer depth, color, marine mammal counts, sea ice freeboard, snow/ice/glacier thickness, melt pond albedo, marine gravity anomalies, etc. Crewed aircraft can also land and take surface stations over a line or grid of stations. Increasingly, uncrewed aircraft operations in polar environments are also used for many applications that require high endurance, high bandwidth data telemetry, and a multitude of sensor systems. In this session, we solicit abstracts on all aspects of this subject applied to polar and subpolar systems, including physical, biological, and possibly human-dimension studies. If there is interest, a panel discussion may be included at the end to solicit ideas and encourage networking.
