This dataset contains gaseous elemental mercury (Hg(0)) concentrations measured in the Central Arctic during the Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC) expedition. The backbone of MOSAiC was the year-round operation of the Research Vessel Polarstern that drifted with the sea ice across the Central Arctic from October 2019 to September 2020. Measurements were performed onboard Polarstern in the University of Colorado sea-laboratory container installed below deck in the forward cargo hold. A ~50 meter (m) long Teflon sampling line was deployed from the container to the bow crane to allow measurements forward of the vessel. This dataset is an archive of 30-minute averaged Hg(0) concentrations.
