Short summary
During the R/V Xuelong cruise observation over the Ross Sea, Antarctica, the mass concentrations of water-soluble Ca2+ and the mass spectra of individual calcareous particles were measured. Our results indicated that lower temperature, lower wind speed, and the presence of sea ice may facilitate Ca2+ enrichment in sea spray aerosols and highlighted the potential contribution of organically complexed calcium to calcium enrichment, which is inaccurate based solely on water-soluble Ca2+ estimation.
