To evaluate the role of Antarctic aeolian transport in surface chemistry homogenization, fifty-three samples of aeolian material from the McMurdo Dry Valleys region of Antarctica were collected and analyzed for water-soluble major ions and nutrients at a 1:5 sediment:water ratio. Samples were collected seasonally from Alatna Valley, Victoria Valley, Miers Valley, and Taylor Valley (Taylor Glacier, East Lake Bonney, F6 (Lake Fryxell), and Explorer’s Cove) at five heights (~5, 10, 20, 50, 100 cm) above the surface between 2013 and 2015.

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.
