Phase contrast tomography of Arctic sea ice cores from the MOSAiC expedition

The experiment will build on a set of Arctic sea ice cores recently collected during the largest Arctic expedition in history (MOSAiC,’Multidisciplinary drifting
Observatory for the Study of Arctic Climate’, October 2019-September 2020, http://www.mosaicexpedition.org). These cores contain important and still unraveled
information about the sea ice properties during the MOSAiC drift. We aim for phase-contrast tomography and hierarchical scanning of several full sea ice cores
from MOSAiC, exploring the unique possibility at BM18 to scan large sample volumes with locally high resolution. The experiment will set a benchmark in 3D
image quality of sea ice microstructure and produce an open source dataset be relevant for many polar research topics and groups within and outside the
MOSAiC consortium.
