Geochemical flux on Commonwealth glacier

Summary

Abstract: 

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.
