AI Article Synopsis
- The study investigates how biological properties of seawater, specifically chlorophyll-a and bacteria concentrations, affect sea spray aerosols (SSA) at a coastal site in Korea across different seasons.
- Chlorophyll-a levels were measured, showing a significant increase from an average of 1.75 μg/l in fall to 5.11 μg/l in summer.
- The findings revealed that the organic content in SSA was higher in summer (68%) compared to fall (49%), indicating that increased phytoplankton biomass in summer enhances the organic components of SSA.
Article Abstract
This study is to investigate the effect of biological seawater properties on sea spray aerosols (SSA). Concentrations of chlorophyll-a and bacteria were measured at coastal site in Korea in fall and summer seasons. Also, aerosol mass spectrometer (AMS) was used to determine chemical constituents (organics, sulfate, nitrate, ammonium, and chloride) of non-refractory submicrometer aerosols sprayed from seawaters using a bubble bursting system. The average concentration of chlorophyll-a in seawater in fall was 1.75±0.78μg/l, whereas it significantly increased to 5.11±2.16μg/l in summer. It was found that the fraction of organics in the submicrometer SSA was higher in summer (68%) than fall (49%), and that the organic fraction in the SSA increased as the concentration of chlorophyll-a increased in seawater, suggesting that the high phytoplankton biomass in seawater could lead to the enhancement of organic species in the SSA.
