A study of the sea-salt chemistry using size-segregated aerosol measurements at coastal Antarctic station Neumayer
Aerosol chemical and physical properties were measured in 2010 at Neumayer research station, Antarctica. Samples for chemical analysis (ion chromatography) were collected using a Teflon/Nylon filter combination (TNy) sampler, and with a multi stage low pressure impactor (SDI). Particle number concen...

Aerosol chemical and physical properties were measured in 2010 at Neumayer research station, Antarctica.

About 50% of the sea salt aerosol mass was found in the submicron size range. Below 0.2 μm of particle aerodynamic diameter the contribution of sea salt aerosols was negligible.
