Linda Thielke is a PhD candidate under the supervision of Dr. Gunnar Spreen at the University of Bremen. After she studied Meteorology in Hamburg with one semester Arctic Geophysics at the University Centre of Svalbard, she started her PhD in 2019 as part of the International Research Training Group ArcTrain. Her research focus is on the winter heat exchange at the Arctic sea ice surface based on helicopter-borne observations of the MOSAiC expedition in combination with satellite data.
With her contribution at the virtual EGU General Assembly 2021, she presented surface temperature maps as an advanced, high spatial resolution data product from helicopter-borne thermal infrared imaging during the MOSAiC expedition. Lead fractions are determined for all flights, from a local to a regional scale, based on the temperature distribution. This allows the investigation of its temporal evolution for the whole winter season 2019/2020. The further derived thin ice thicknesses for the lead areas provide additional information about the surface characteristics of the covered Arctic sea ice.
