25 Years of Antarctic Land Ice Elevation Change Anomalies (West Coast Fly Over)

This data visualization depicts the last 25 years of land ice elevation change. Areas in red indicate land ice loss. Areas in blue are regions that saw land ice elevation gains. The camera starts with a view of the Earth and then flies down to Antarctica where it pauses to watch the 25 years of data unfold. Once the data reaches the end of 2017, the camera then flies down over the western Antarctic coast and then backs up across the central region.
As more and more land ice elevation data is collected in Antarctica, NASA scientists are amassing the vasts amounts of data and using it to track land ice elevation changes over time. This effort is part of the NASA MEaSUReS ITS_LIVE project.
