研究実績の概要

The purpose of this study is to understand the roles of microbes and organic matter originating from the sea surface microlayer (SML) in controlling the distribution and abundance of ice nuclei (IN) in the atmosphere. The lack of understanding and research in the field of SML hampers the effort to predict the contribution of marine aerosol towards the global climate and radiation budget accurately. In this study, we managed to identify the ice nucleating bacteria from the SML and from the water body directly below it (UW). We also managed to study the characteristic and nature of the ice nucleation protein present in the ice nucleating bacteria.
