Abstract
Marine aerosol particles from the Equatorial Pacific were studied usin g transmission electron microscopy: Sea-salt aggregates consist largel y of NaCl and Na-Ca sulfate crystals. Variations in the composition of sea-salt aggregates occur, and these may reflect the effects of relat ive humidity. There are several species of submicron, S-bearing partic les, presumably including ammonium sulfate and strong acids. Diatom fr agments are common, and sparse kaolinite and rutile crystals are the m ineral component of this marine aerosol. The samples we studied appear ed to be free of obvious anthropogenic effects.
