Article Synopsis
- Ice-nucleating particles (INPs) are key aerosols in the atmosphere that trigger ice formation, but predicting their concentrations in climate models is difficult.
- Researchers developed a method to differentiate INP sources from dust, sea spray aerosol (SSA), and bioaerosol, using data from Bodega Bay, California.
- Findings showed that bioaerosols were the main contributor to INPs at certain temperatures, while current models accurately reflected dust and SSA INP levels but struggled with bioaerosols, indicating the need for further study on their emission and efficiency.
Article Synopsis
- Sea spray aerosol (SSA) particles significantly affect climate by scattering solar radiation and aiding in cloud formation, with their composition influenced by oceanic biological processes, especially during phytoplankton blooms.
- A mesocosm study using natural seawater revealed that two distinct phytoplankton blooms led to different SSA chemical compositions; the first bloom produced organic-rich SSA, while the second did not.
- The research highlights the complexity of SSA composition influence, showing that it is governed not only by phytoplankton abundance (measured by chlorophyll-a) but also by microbial degradation processes affecting the organic material produced during these blooms.

Article Synopsis
- * Researchers developed a new method using microbial processes, specifically inducing phytoplankton blooms, to manipulate seawater and SSA particle composition effectively.
- * This controlled approach allows for the study of how changes in seawater impact SSA particle chemistry, facilitating future research on the physical and chemical characteristics of these important aerosols.
