Mercury in the Arctic Atmosphere: Springtime Cycling Near and Over the Sea Ice
The objective of the work described in this thesis is to improve our understanding of factors that affect the depletion of gaseous elemental mercury (GEM) from the atmosphere during the Arctic springtime. This was accomplished through research undertaken and described in three publications. Atmosphe...
