We measured sulfate oxygen and nitrate oxygen and nitrogen isotopes from the Greenland Ice Sheet Project 2 ice core from Greenland in 15 discrete samples (~ 2 kg of ice each) over the last glacial-interglacial cycle (from 976 - 97,681 years before present, between 264 - 2735 meters depth). Each sample spans ~50 cm depth, representing 2-200 years of snow accumulation. We also performed continuous measurements of nitrate nitrogen and oxygen isotopes on 112 samples over two Dansgaard-Oeschger (D O) events (DO-12 and -13 from 42,967 - 49,002 years before present). The length of each sample is 0.5-1.0 meter, representing ~50 years of snow accumulation.
