Our objectives in this spring cruise were to make in situ surface based measurements of marine aerosol sources, composition and properties, and provide comparison with the behavior of marine primary aerosol produced in the bubble tank experiments. Aerosol measurements will be used to determine the biogenic and anthropogenic nature of aerosol sources within the Arctic boundary layer and how these aerosol sources changes with changing ice conditions. CCN (Cloud Condensation Nucleus) measurements, made as function of aerosol size and super-saturation, will be used as input in cloud microphysical models to investigate their influence on aerosol-cloud feedback sensitivity. Bubble tank results obtained during the spring cruise (and from post-cruise experiments) will be used to provide a primary multi-component sea-spray aerosol flux parameterization for direct incorporation into the global aerosol modeling.
