Short summary

Hygroscopic growth factors at 85 % relative humidity (GF(85 %)) were quantified along with particle composition for primary sea spray aerosol (SSA) particles generated in marine aerosol reference tanks (MARTs) from seawater in which two independent phytoplankton blooms were induced. The observed 5 to 15 % depression in the GF(85 %) values (relative to pure sea salt) is consistent with the large observed volume fractions of non-refractory organic matter (NR-OM) comprising the SSA.
