Variable wind speeds over the ocean can have a significant impact on formation mechanism and physical-chemical properties of sea spray aerosols (SSA), which in turn influence their climate-relevant impacts. Herein, for first time, we investigate effects speed size-dependent morphology composition individual nascent SSA generated from wind-wave interactions natural seawater within channel as function size particle-to-particle variability. Filter-based thermal optical analysis, atomic force...
Abstract. Sea spray aerosol (SSA) represents one of the most abundant natural types, contributing significantly to global mass and optical depth, as well both magnitude uncertainty in radiative forcing. In addition its direct effects, SSA can also serve ice-nucleating particles (INPs), which are required for initiation cloud glaciation at temperatures warmer than ca. −36 °C. This study presents initial results from CHaracterizing Atmosphere-Ocean parameters SOARS (CHAOS) mesocosm campaign,...
Harmful algal blooms (HABs) are a rising health and environmental concern in the United States, particularly South Florida. Skin contact ingestion of contaminated water or fish other seafood have been proven to severe toxicity humans some cases. However, impact aerosolized HAB toxins is poorly understood. In particular, knowledge regarding either immediate long-term effects exposure cyanotoxins produced by freshwater blue-green algae does not exist. The aim this study was probe...
Viscosity, or the "thickness," of aerosols plays a key role in atmospheric processes like ice formation, water absorption, and heterogeneous kinetics. However, viscosity sea spray (SSA) has not been widely studied. This research explored relationship between particle size authentic SSA particles through bounce, atomic force microscopy analysis, predictive modeling from molecular composition. The study found that 40 nm had estimated viscosities around 104 Pa·s bounce fractions three times...
Abstract. Sea spray aerosol (SSA) represent one of the most abundant natural types, contributing significantly to global mass and optical depth, as well both magnitude uncertainty radiative forcing. In addition their direct effects, SSA can also serve ice nucleating particles (INPs), which are required for initiation cloud glaciation at temperatures warmer than ∼-36 °C. This study presents initial results from CHaracterizing Atmosphere-Ocean parameters in SOARS (CHAOS) mesocosm campaign, was...
Harmful algal blooms (HABs) can generate toxins that be aerosolized and negatively impact human health through inhalation. HABs are often found in waterways near residences, therefore, HAB potentially affect both indoor outdoor air quality. Given predicted to increase worldwide, effective mitigation strategies needed prevent the inhalation of toxins. In this work, we characterized particle filtration efficiency using sizing instruments as well mass concentration different congeners...
