Trends in Atmospheric Mercury Concentrations over the Atlantic Ocean and at the Wank Summit, and the Resulting Constraints on the Budget of Atmospheric Mercury
In 1977 – 1980, 1990, and 1994 we measured the latitudinal distribution of atmospheric mercury over the Atlantic Ocean. The results of these measurements show a pronounced concentration gradient between the no...
