Sonification of the atmospheric carbon record over the past 800,000 years

This piece is part of a collection of sound compositions called Timescales, which sonifies datasets spanning different time scales of the atmospheric carbon record. Glaciations is a musical sonification of atmospheric carbon dioxide inferred from ice cores, from 800,000 years ago to the present. This scale encompasses the small shifts in earth's orbit which drove the rise and fall of eight successive ice ages and alternating warm periods. The intention behind the compositional choices in this composition is to evoke a sense of vastness and wonder, and to create a sonic landscape of planetary motion and deep time.
