As an international partner, the Alfred Wegener Institute for Polar and Marine Research provides measurements of sea ice thickness obtained by a helicopter based electromagnetic (EM) ice thickness sensor. A description of the system is given in Haas et al. (2007). In principle the distance between the instrument and the sea surface is estimated with an electromagnetic signal, regardless of the overlying sea ice cover. The distance to the top snow cover is estimated with a laser altimeter. Consequently all thickness data refers to the snow plus ice or total thickness. * Please note: AEM data from 2013 onwards were acquired using a new sensor known as the Multi frequency Airborne Sea Ice Explorer (MAiSIE). While the quicklook data currently provided are compatible with earlier data, the dataset will be updated in the future when an improved calibration algorithm (made possible by sensing advances in MAiSIE) is implemented Data Citations: Pfaffhuber, A.
