Concentration, size distribution and chemical composition of snow particles, sea salt aerosol and snow on sea ice in the Weddell Sea (Antarctica) during austral winter/spring 2013
GB/NERC/BAS/PDC/01239

Summary

Abstract:
Two consecutive cruises in the Weddell Sea, Antarctica, in winter/spring 2013 provided the first direct observations of sea salt aerosol (SSA) production from blowing snow above sea ice, thereby validating a model hypothesis to account for winter time SSA maxima in polar regions not explained otherwise. Concentration, size distribution and chemical composition of airborne snow particles, sea salt aerosol and snow on sea ice where measured on board RV Polarstern as well as on the sea ice during ice stations.

Funding was provided by NERC projects NE/J023051/1 and NE/J020303/1.
