The abnormal spikes detected in some CO and CO_2 polar ice core records indicate persistent chemical activity in glacial ice. Since CO and CO_2 spikes are correlated, and their amplitudes scale with reported CO/CO_2 yields for the photolysis of dissolved natural organic matter, a common photochemica...
