Short summary

Summertime and wintertime Antarctic sea spray aerosol (SSA) samples with a drastic chlorophyll-a level contrast were investigated on a single-particle basis. X-ray analysis showed that the contents of C, O, Ca, S, and Si were more elevated, whereas Cl was more depleted for the summertime sample. The combined application of RMS and ATR-FTIR imaging showed Mg hydrate salts of alanine and Mg salts of fatty acids were major organic species in nascent Antarctic SSAs.
