Publication abstract: Sea spray aerosols (SSA) are generated at the ocean-air interface during wave breaking and provide a significant contribution to the climatic-relevant processes via directly by scattering and absorbing solar radiation, and indirectly by activating into cloud condensation nuclei (CCN) or ice nucleating particles (INP). Depending on the generation mechanism on the ocean surface, SSA can exhibit size dependence particle-to-particle variation in physicochemical properties such as the morphology or mixing state, chemical composition, phase states, and water uptake. However, a complete study to correlate the field collected individual submicron SSA particles morphology or mixing state with their corresponding chemical composition, phase state, and water uptake as a function of size, relative humidity (RH), and biological activity in the seawater is not been recorded yet. Herein, the AFM-based imaging and force spectroscopy was used to directly probe the substrate deposited, submicron individual SSA particles morphology, phase state, and water uptake as a function of RH, particle size, as well as the biological activity in water. Five different morphologies of SSA particles were identified over the phytoplankton bloom period. Size dependent phase state measurements revealed the variation of particles phase states as a function of particle size, morphology, as well as the bloom designation day. The water uptake studies showed the different water uptake abilities of the particles depending on the particle morphology and the bloom designation day. Overall, results confirmed that the individual submicron SSA can have a significant difference between the morphologies, phase state, and water uptake depending on the particle size and the biological activity in the seawater.
