Soil invertebrate surveys from the Shackleton Glacier region of Antarctica during the 2017-2018 austral summer

Summary

Abstract: 

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. This data package includes invertebrate abundances (nematodes, tardigrades, rotifers) for each sample categorized by species, sex, and maturity (juvenile, adult).
