22-year sea level rise - TOPEX/JASON

Monday, December 5, 2016

This visualization shows total sea level change between 1992 and 2014, based on data collected from the TOPEX/Poseidon, Jason-1 and Jason-2 satellites. Blue regions are where sea level has gone down, and orange/red regions are where sea level has gone up. Since 1992, seas around the world have risen an average of nearly 3 inches.

The color range for this visualization is -7 cm to +7 cm (-2.76 inches to +2.76 inches), though measured data extends above and below 7cm (2.76 inches). This particular range was chosen to highlight variations in sea level change.
