Safewin 2011 airborne EM sea ice thickness measurements in the Baltic Sea
This report summarizes the results of airborne electromagnetic (EM) ice thickness surveys undertaken during the SafeWin winter field campaign in 2011, using a helicopter‐towed EM Bird. Surveys were flown during and after the RV Aranda sea ice cruise in the Sea and Bay of Bothnia, between March 2 and...

This report summarizes the results of airborne electromagnetic (EM) ice thickness surveys undertaken during the SafeWin winter field campaign in 2011, using a helicopter‐towed EM Bird. Surveys were flown during and after the RV Aranda sea ice cruise in the Sea and Bay of Bothnia, between March 2 and 7, 2011. Due to severe ice conditions, RV Aranda arrived late at her final destination in the Bay of Bothnia. Therefore, and due to further delays related to technical problems with the helicopter and contaminated fuel, surveys from the ship could only be performed on two days, before the ship had to return south. However, we decided to keep the EM Bird on land in Kokkola, and after some careful training by Alec Casey, Mikko Lensu was able to perform surveys on four more days.
