Comparison of along track EM ice thickness profiles with ship performance data
During the Arctic Demonstration and Exploratory Voyage (ARCDEV) in April/May 1998 to the Kara Sea extensive continuous electromagnetic (EM) ice thickness measurements were performed along the route on board the icebreaker KAPITAN DRANITSYN. The measurements were compared with ship speed and power da...
