英文摘要	Dust aerosols play important roles in marine ecosystems and carbon export once they are deposited and dissolved in the ocean. The effect of dust aerosols on chlorophyll-a (Chl-a) concentrations and particulate organic carbon (POC) in the subarctic North Pacific Ocean (SNPO) received particular attention due to their influence on air-sea carbon flux. However, significant uncertainties remain in understanding the long-range transport, atmospheric process and deposition of dust/polluted dust aerosols and their impacts on oceans. A trans-Pacific dust/polluted dust episode from 12 to 17 March 2015 was analyzed using satellite data and the WRF-Chem model. Both results confirmed that dust/polluted dust aerosols were transported from the Taklimakan Desert to the SNPO in 4–5 days under the effect of the westerly jet system. Anthropogenic aerosol mixed with dust aerosol during atmospheric process. The total deposition of dust aerosols based on model results over the research region (40°-50°N, 150°-155°E) in the SNPO from 16 to 18 March 2015 was 6.8 mg m−2. Both Chl-a concentrations and POC increased nearly 50% after the dust deposition. Dust deposition might leads to an increase in phytoplankton by iron fertilization effect. In addition, polluted dust deposition might be an important source of POC in the surface ocean. © 2019 Elsevier B.V.
