The sea surface microlayer (SML) is the thin layer of water that resides at the air-sea interface, typically extending from the ocean surface down to about 1 millimeter (up to several millimeters in some cases). This layer is characterized by distinct physical, chemical, and biological properties when compared to the underlying water column.
