This data visualization shows accumulated mass change over Antarctica from 1900 to 2000. This visualization includes a colorbar and corresponding accumulation range.

Scientists have collected Ice core measurements across Antarctica for many years. Scientists at NASA/Goddard and the British Antarctic Survey have assembled over 50 of these ice core measurements and have analysized them to derive a map of the mass accumulation change throughout the 20th Century (1900-2000).

This data visualization shows accumulated mass change over Antarctica throughout the 20th Century. (No colorbar or corresponding dates are provided with this visualization.)

This animation contains the corresponding date overlay for the last year of accumulated mass change data depicted in the data visualization. This layer is intended for video editors who desire to recomposite the final visualization in a slightly different style.

Colorbar for accumulated mass change of Antarctic snow. Units are in Gigatons. Reds indicate areas of mass loss. Blues indicate areas of mass gain.
