Despite decades of marine environment studies, a direct relationship has yet to be established between ocean biol. and physicochem. SSA properties.  The ability to establish such relationships is hindered because SSA measurements are typically dominated by overwhelming background aerosol concns., even in remote marine environments.  This work describes a newly developed approach to reproduce SSA chem. complexity a lab. setting, comprising a unique ocean/atm. facility equipped with actual breaking waves.  A mesocosm expt., performed with natural seawater using controlled phytoplankton and heterotrophic bacteria concns., showed SSA size and chem. mixing state are acutely sensitive to the aerosol prodn. mechanism and to the type of biol. species present.  The largest redn. in SSA hygroscopicity occurred as heterotrophic bacteria concns. increased, whereas phytoplankton and chlorophyll-a concns. decreased, directly corresponding to a change in mixing state in the smallest size range (60-180 nm).  Using this newly developed approach to generate realistic SSA, systematic studies can now be performed to advance the fundamental understanding of the effect of ocean biol. on SSA chem. mixing state, heterogeneous reactivity, and resulting climate-relevant properties.

Single particle anal. of SSA particles was performed, integrating transmission electron microscopy with energy dispersive x-ray anal. and scanning transmission x-ray microscopy with near edge x-ray absorption fine structure spectroscopy, focusing on quantifying the relative fractions of different particle types from 30 nm to 1 μm.  SSA particles were produced from seawater in a unique ocean/atm. facility equipped with breaking waves.  Changes to SSA compn. and properties after adding biol. (bacteria, phytoplankton) and org. material (ZoBell growth media) were probed.  Sub-micrometer SSA particles could be sepd. into 2 distinct populations: one with a characteristic sea-salt core composed primarily of NaCl and an org. C and Mg2+ coating (SS-OC); and a second type consisting of org. C (OC) species more homogeneously mixed with cations and anions, but not Cl-.  SS-OC particles exhibited a range of sizes, compns., morphologies, and element distributions within each particle.  Following addn. of biol. and org. material to seawater, a change occurred in particle morphol. and crystn. behavior assocd. with increasing org. content for SS-OC particles.  The fraction of OC-type particles, mainly present at &lt;180 nm, was dramatically enhanced with increased biol. activity.  These changes with size and seawater compn. have important implications for atm. processes, e.g., cloud droplet activation and heterogeneous reactivity.
