Sea ice surface roughness data were obtained during the PoleAirship campaign in Apr, 2007 with a Single Beam Laser Altimeter (SBLA) mounted inside an electromagnetic system (EM-Bird) towed at 10-30 m height above surface by a Helicopter (Mil MI-8). A method developed by Hibler (1972) was used to a)...
