资源简介：
Model primary marine aerosol (mPMA) was produced by bubbling clean air through flowing natural seawater in a high-capacity generator deployed on ships in the eastern North Paci fic and western North Atlantic Oceans. Physicochemical properties of seawater and mPMA were quanti fied to characterize factors that modulated production. Differences in surfactant organic matter (OM) and associated propertiesincluding surface tension sustained plumes with smaller bubble sizes, slower rise velocities, larger void fractions, and older surface ages in biologically productive relative to oligotrophic seawater. Production efficiencies for mPMA number (PE num) and mass (PE mass) per unit air detrained from biologically productive
