Polysaccharides, Proteins, and Phytoplankton Fragments: Four Chemically Distinct Types of Marine Primary Organic Aerosol Classified by Single Particle Spectromicroscopy

Figure 2

Individual (grey) and average (black) NEXAFS spectra of the four marine particle types including (a) PsI, (b) PsII, (c) calcareous phytoplankton fragments, and (d) proteinaceous particles. Illustrations in each panel represent commonly observed morphologies associated with each spectra type. The observed size range for each type is shown below the illustrations.
