We present measurements gas measurements from the South Pole Ice Core, including the isotopic composition of molecular nitrogen (δ15N) and argon (δ40Ar), and the argon-nitrogen ratio (δAr/N2). The measurements were made between approximately 490 and 1310 m depth, which is between 5 and 30 kyr BP on...
