Organic Sea Spray Aerosol: Diversity and Hygroscopicity

by Karolina Seigel, PhD student the Department of Meteorology (MISU)

Time: 26 April 2018, 14h15–14.45
Venue: Rossbysalen C609, Arrhenius Laboratory, 6th floor

Abstract
Sea spray aerosol (SSA) is a natural source of aerosol, derived from wave-breaking and bubble bursting at the sea-air interface. Primary SSA consists of an inorganic (sea salt) and an organic part (e.g. viruses, bacteria, saccharides and fatty acids), where the organic part is a result of marine microbiological activity in the surface microlayer (SML) of the ocean. Global climate models tend to make the assumption that primary organic SSA particles from a single source exhibit the same cloud condensation nuclei (CCN) characteristics, but Cochran et al. (2017) have shown that the connection between SSA and ocean biology is far more complex.
