Ice covers 10 percent of Earth's surface and helps moderate the planet's temperature.

It’s not only water processes that play a role in global sea level rise – ground movements can play a significant role as well.

The Jason-3 satellite, launched on January 17, 2016, is allowing scientists to continue a 23-year record of crucial ocean monitoring.
