Sea ice surface roughness data were obtained during the ARK-XX/2 campaign in Jul-Aug, 2004 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 (RV-Polarstern Helicopter). A method developed by Hibler (1972...
