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.
