Sea Ice Versus Storms: What Controls Sea Salt in Arctic Ice Cores? ...
AbstractThe sea ice surface is thought to be a major source of sea salt aerosol, suggesting that sodium records of polar ice cores may trace past sea ice extent. Here we test this possibility for the Arctic, using a chemical transport model to simulate aerosol emission, transport, and deposition in...
