Sonification Of Arctic Sea Ice by Judy

This track sonified the satellite record of Arctic Sea Ice extent -- an index of total ice cover in the Arctic Ocean -- from 1979 to 2016.

Each note represents one month of data. High pitch indicates more ice that month. Low pitch indicates more melt.

The volume for all 12 months of the year is controlled by the summer minimum. In this way, you can hear both the monthly variations, and the year-to-year changes.

I have overlaid natural sound recordings of waves, ships, and bowhead whales.
