GISP2 Stable Isotopes (Deuterium, Deuterium Excess, and Oxygen)
DATA ORGANIZATION
The data consist of two files, each with a different structure:
GISP2_Holocene_deuterium.txt
Column 1 is the top depth (m) of each discrete sample, column 2 is the bottom
depth (m) of each discrete sample, column 3 is the discrete sample length (m),
and column 4 is delta deuterium (per mil) over the depth interval with a
measured precision of 0.5 per mil.
GISP2_glacial_Isotopes.txt
Column 1 is the top depth (m) of each discrete sample, column 2 is the bottom
depth (m) of each discrete sample, column 3 is delta deuterium (per mil) over
the depth interval with a measured precision of 0.1 per mil, column 4 is delta
oxygen-18 (per mil) with a measured precision of 0.07 per mil, column 5 is
deuterium excess calculated from columns 3 and 4.
