Soil samples were collected from the Shackleton Glacier region, located in the Queen Maud Mountains during the 2017-2018 austral summer. A subset of 27 samples were analyzed for stable isotopes of S, N, C, and O in nitrate, sulfate, and (bi)carbonate. ). δ15N-NO3 values ranged from -47.8 to 20.4‰ and, while all Δ17O-NO3 values are positive, they ranged from 15.7 to 45.9‰. δ34S-SO4 and δ18O-SO4 values ranged from 12.5 and 17.9‰ and -14.5 to -7.1‰, respectively. Total inorganic carbon isotopes ((bi)carbonate) in bulk soil samples ranged from 0.2 to 8.5‰ for δ13C and -38.8 to -9.6‰ for δ18O.
