Abstract

Abstract: This study is to investigate the effect of biological seawater properties on sea spray aerosols (SSA). Concentrations of chlorophyll-a and bacteria were measured at coastal site in Korea in fall and summer seasons. Also, aerosol mass spectrometer (AMS) was used to determine chemical constituents (organics, sulfate, nitrate, ammonium, and chloride) of non-refractory submicrometer aerosols sprayed from seawaters using a bubble bursting system. The average concentration of chlorophyll-a in seawater in fall was 1.75 ± 0.78 μg/l, whereas it significantly increased to 5.11 ± 2.16 μg/l in summer. It was found that the fraction of organics in the submicrometer SSA was higher in summer (68%) than fall (49%), and that the organic fraction in the SSA increased as the concentration of chlorophyll-a increased in seawater, suggesting that the high phytoplankton biomass in seawater could lead to the enhancement of organic species in the SSA. Highlights: Effect of phytoplankton biomass in seawater on sea spray aerosols was examined. Organic fraction in sea spray aerosols increased with increasing chlorophyll-a concentration. Marine organic mass spectra in sea spray aerosols were identified.
