Multi-decadal decline of mercury in the North Atlantic atmosphere explained by changing subsurface seawater concentrations
We analyze 1977-2010 trends in atmospheric mercury (Hg) from 21 ship cruises over the North Atlantic (NA) and 15 over the South Atlantic (SA). We find a steep 1990-2009 decline of -0.046±0.010 ngm-3 a -1 (-2.5% a-1) over the NA (steeper than at Northern Hemispheric land sites) but no significant dec...
