Geochemical flux on McMurdo Dry Valleys Commonwealth glacier

As part of a geochemical study of the Commonwealth Glacier in Taylor Valley,
Antarctica, two 3-meter snow pits were dug in the accumulation zone and analyzed for
major ions by ion chromatography. This dataset shows the mean annual atmospheric
flux of chloride, sulfate, nitrate, and calcium to the Commonwealth Glacier. Determination
of the atmospheric flux of these ions to the glacier surface aids in assessing the chemical
composition of precipitation to the McMurdo Dry Valleys and the role of glaciers in the
geochemical cycles of the region.
