Diurnal Emissions of Sea Spray Aerosols in Algal Blooms.

ABSTRACT: Understanding the factors that influence the production of sea spray aerosols (SSA) is crucial for better understanding their impact on our climate. However, the role of oceanic microbial activity in contributing to SSA production is still underexplored. Here, we investigated the dynamics of SSA number concentration (N_SSA) during induced algal blooms within three airtight mesocosm enclosures. Monitoring algal abundance throughout a 24-day experiment revealed two main blooms: a mixed algal bloom followed by an extensive bloom of the coccolithophore Gephyrocapsa huxleyi and its subsequent demise. We observed two main patterns in N_SSA: (1) a diurnal variation with higher daytime emissions; and (2) a progressive decrease in N_SSA thro
