The enrichment of DOC and POC in the SML and in aerosol particles. Comparison of the seawater and aerosol ratios of DOC (WSOC) to sodium (Na⁺) (a) and POC (WISOC) to Na⁺(b) to illustrate their enrichments in SML and aerosol particles at different wind and chl-a conditions. The secondary organic aerosol (SOA) arrow in (a) illustrates that additional DOC originating from the gas phase is likely to contribute to the concentrations measured on aerosol particles.
