| Outline of Final Research Achievements |
The lack of understanding and research in the field of sea surface microlayer (SML) hampers the effort to predict the contribution of marine aerosol towards the global climate and radiation budget accurately. This statement rings true as well for the field of ice nucleation study especially in marine environment, whereby previous research has shown that these particles have the ability to control cloud lifetime, precipitation and radiative properties. In short, this study on the microbial dynamics in coastal SML with regards to ice-nucleating bacteria will provide significant insights into the yet-to-be-studied microbial roles in controlling atmospheric processes over large swath of ocean as well as regional climate.

| Academic Significance and Societal Importance of the Research Achievements |
Ice nucleation particles play an important role in regulating oceanic and atmospheric processes such as cloud formation. Ice nucleation bacteria isolated and characterized from this study can help with the understanding on how these bacteria contributes or affect the atmospheric processes.
