During the 2017-2018 austral summer, a survey of soil invertebrate diversity and abundance was conducted throughout the Shackleton Glacier region of Antarctica to investigate whether habitat suitability, taxonomic diversity, and community composition follow predictable temporal patterns after the Last Glacial Maximum (LGM). Soil samples were collected along elevation transects from twelve ice-free areas to capture maximum variation in soil properties, geochemistry, and surface exposure age.

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.
