  "description": "Abstract. Marine biota is an important source of atmospheric\naerosol particles in the remote marine atmosphere. However, the relationship between new particle formation and marine biota is poorly quantified.\nLong-term observations (from 2009 to 2016) of the physical properties of\natmospheric aerosol particles measured at the Antarctic Peninsula (King\nSejong Station; 62.2\u2218\u2009S, 58.8\u2218\u2009W) and satellite-derived\nestimates of the biological characteristics were analyzed to identify the\nlink between new particle formation and marine biota. New particle formation\nevents in the Antarctic atmosphere showed distinct seasonal variations, with the highest values occurring when the air mass originated from the ocean\ndomain during the productive austral summer (December, January and February).\nInterestingly, new particle formation events were more frequent in the air\nmasses that originated from the Bellingshausen Sea than in those that\noriginated from the Weddell Sea. The monthly mean number concentration of\nnanoparticles (2.5\u201310\u2009nm in diameter) was >2-fold higher when the air\nmasses passed over the Bellingshausen Sea than the Weddell Sea, whereas the\nbiomass of phytoplankton in the Weddell Sea was more than \u223c70\u2009%\nhigher than that of the Bellingshausen Sea during the austral summer\nperiod. Dimethyl sulfide (DMS) is of marine origin and its oxidative\nproducts are known to be one of the major components in the formation of new\nparticles. Both satellite-derived estimates of the biological\ncharacteristics (dimethylsulfoniopropionate, DMSP; precursor of DMS) and\nphytoplankton taxonomic composition and in situ methanesulfonic acid (84\ndaily measurements during the summer period in 2013 and 2014) analysis\nrevealed that DMS(P)-rich phytoplankton were more dominant in the\nBellingshausen Sea than in the Weddell Sea. Furthermore, the number\nconcentration of nanoparticles was positively correlated with the biomass of\nphytoplankton during the period when DMS(P)-rich phytoplankton predominate.\nThese results indicate that oceanic DMS emissions could play a key role in\nthe formation of new particles; moreover, the taxonomic composition of\nphytoplankton could affect the formation of new particles in the Antarctic\nOcean.",
