July, 2004: Watch and Listen to Seasonal Changes in Martian Polar Ice

The number of hydrogen gamma rays detected by the Mars Gamma Ray Spectrometer (GRS) at Mars decreases as carbon dioxide (CO2) ice covers a given pole during the winter months. As this CO2 ice sublimates away during the summer months, the water ice underneath is exposed and the hydrogen signal increases. The Mars GRS science team has created both a visual animation and a musical sonification of this seasonal variation on Mars. Go to the following website to download this unique educational product that allows you to see and hear Mars data!

Visit our sonification page.

Below is a screenshot of the sonification of GRS data.
