Welcome
Welcome to the Princeton Polar Ice website! We present research
results on the mass change of Earth's ice sheets from gravity
measured by the GRACE satellites. This site discusses Greenland,
Antarctica, and the Arctic, between about 2003 and about 2015.Details about the methodology and the computer routines can be found on the Methods and Code pages.
