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.

Snow patches within and adjacent to stream channels in the Fryxell Basin of Taylor Valley, Antarctica were sampled during the 2021-2022 austral summer as part of the McMurdo Dry Valleys Long Term Ecological Research program. This data package includes snow pit measurements (snow temperature, depth, density, and water equivalent) as well as chemical characteristics of snow samples that were analyzed for nutrient, cation, and anion concentrations.
