GISP2 (B and D Core) Methane Concentrations
The data include methane data from the Greenland Ice Sheet Project 2 (GISP2) B & D Cores. Gas ages were calculated according to the methods described in Brook et al. 1996, and are subject to change. Ice ages were calculated by by linear interpolation from the Meese et al. timescale.
