Sea ice surface roughness data were obtained during the Transdrift-XIII campaign in Apr-May, 2008 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 use...
