英文摘要: The air masses transported from East Asia have a strong impact on the aerosol properties and deposition in the marine boundary layer of the western North Pacific (WNP) during winter and spring. We joined a cruise between 17 Mar. and 22 Apr. 2014 and investigated the changes of aerosol composition and size distribution over the remote WNP and marginal seas. Although the secondary aerosol species (SO4 2−, NO3 − and NH4 +) in remote WNP were influenced significantly by the continental transport, NH4 + concentrations were lower than 2.7 μg m−3 in most sampling days and not correlated with non-sea-salt (nss)-SO4 2- suggesting that the ocean could be a primary source of NH4 +. Moderate Cl− depletion (23%) was observed in remote WNP, and the inverse relationship between Cl− depletion percentages and nss-K+ in aerosols suggested that the transport of biomass burning smoke from East Asia might be a vital extra source of Cl−. Both Asian dust and haze events were encountered during the cruise. Asian dust carried large amounts of crustal elements such as Al and Ti to the WNP, and the dusty Fe deposition may double its background concentration in seawater. Differently, a dramatic increase of dry deposition flux of dissolved particulate inorganic nitrogen was observed during the haze event. Our study reveals that the transport of different continental air masses may have distinct biogeochemical impacts on the WNP by increasing the fluxes of different nutrient elements and potentially changing the nutrient stoichiometry. © 2017 Elsevier Ltd Citation statistics:
