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. Atmospheric mercury depletion events (AMDEs) are now an established phenomenon in the high Arctic whereby the long-lived GEM is oxidized in the air through a series of photochemically-initiated reactions involving halogens and ozone. This chemistry produces reactive gaseous mercury (RGM) and particulate bound mercury (PHg) which both have shorter atmospheric residence times than GEM and deposit more readily to the snow and ice surfaces. This is a means by which mercury can be transferred from the atmosphere to the Arctic environment that was unknown prior to 1995 when AMDEs were discovered. An extensive review paper was completed that summarizes mercury work in the high Arctic in the ten years following the discovery of AMDEs. This review was followed by two papers investigating the processes around atmospheric mercury in the Arctic springtime
