The Arctic is mostly ocean, surrounded by mostly land, and our understanding of Arctic aerosol processes is incomplete due to scarce measurements carried out in sea ice regions. In particular, it is currently not known if these particular regions are sources of aerosols of primary or secondary origin. We present new results from ship-based measurements illustrating that marine new particle production and growth events occur in open ocean and melting sea ice regions in the Chukchi and East Siberian Seas. We report two new particle formation events during which a recently formed nucleation mode (<15 nm diameter) is detected and is observed to slowly grow into an Aitken mode (0.1-3.8 nm/h). Our results suggest that new particle formation occurs in the marine boundary layer contributing to the Arctic aerosol population in the study region for the first time studied and herein reported. 2020-02-01T00:00:00Z https://repository.kopri.re.kr/handle/201206/11089 Title: Molecular characterization of Arctic and Antarctic airborne particulate matter using ultra-high resolution FT-ICR mass spectrometry Authors: Jang, Kyoung-Soon 2020-01-31T00:00:00Z https://repository.kopri.re.kr/handle/201206/13148 Title: Investigation on variation of regions N2O production with field observation Authors: Kim, Il-Nam 2020-01-30T00:00:00Z
