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.

As part of a collaborative investigation between researchers at Rice University, Arkansas State University, University of Rochester, and Ohio State University, lakes of the McMurdo Dry Valleys were sampled at discreet depth intervals during the 2005-2006 field season. Sample splits were subsequently analyzed for chemical and isotopic composition of both gases and dissolved ions, as well as dissolved organic carbon. In addition, cryogenic salts were sampled in the surrounding lake shores in order to determine the salt sources.

To examine temporal and spatial variability in snow chemistry during the 2000-2001 austral summer, snow samples were collected from the accumulation zones of Canada, Commonwealth, and Rhone Glaciers, located in Taylor Valley in the McMurdo Dry Valleys region of Antarctica. Snowpits were excavated to a depth of 2 meters at each location and samples were collected using a depth interval of 3 cm utilizing clean sampling techniques. Snow density was measured in the field at the time of sample collection. Samples were analyzed for major ions in the Crary Lab at McMurdo Station.
