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. ...
