South Pole Ice Core Isotopes of N2 and Ar
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...
