Abstract. The Arctic Ocean is continuously warming, resulting in sea ice retreat, which significantly impacts the marine biogenic sulfur cycle. The formation of aerosols from DMS oxidation and their climatic effects in the polar regions are of great concern. However, the impact of DMS chemistry on atmospheric aerosols in the high Arctic Ocean (AO) is still unclear due to the limitation of field observations and datasets. Gaseous methanesulfonic acid (MSA) and aerosol chemical species (MSA, SO42- and DMA, etc.) were determined simultaneously with a high time resolution (1 hour) in the AO and Pacific Ocean (PO) to reveal the DMS chemistry in these regions. Extremely low MSA concentrations were observed in the high AO (75°–85° N), with an average of only 7.42 ± 6.60 ng•m-3. However, high MSA concentrations, with an average of 168.60 ± 167.60 ng•m-3 were observed in the mid-latitude regions (45°–60° N). Sea salt aerosols were the most dominant source in the high Arctic Ocean, accounting for 88.78 % of the total aerosols, which was much larger than the values in the other regions. The MSA fraction was much lower in the high latitude regions than in the other regions, accounting for only 1.61 % of the total aerosol particles. The latitudinal distribution of MSA was consistent with that of DMS over the AO. Low DMS chemistry was determined based on the low DMS emissions in the HL region. These results highlight the contribution of DMS chemistry to atmospheric aerosols and extend the knowledge of how biogenic aerosols impact the regional atmosphere in the high AO.

Short summary
Extremely low contribution of DMS chemistry to the aerosols over the high AO was determined by the inhibition of marine phytoplankton, which extends the knowledge how will biogenic sulfur cycle impact the regional climate as AO sea ice retreat in the future.
