A team of researchers used Grace data to estimate Antarctica's ice mass between 2002 and 2009. Their results, published Nov. 22 in the journal Nature Geoscience, found that the East Antarctic ice sheet is losing mass, mostly in coastal regions, at an estimated rate of 57 gigatonnes a year.
There are strong indications that mass loss from the Greenland ice sheet has recently accelerated after atmospheric warming and increased runoff and increased ice discharge through the acceleration of outlet glaciers in the west and east. >>
A coding error in the software that computes Global Isostatic Adjustment (=PGR) was found. Its effect is less than 2 mm/yr everywhere over the globe, less than 0.05 mm/yr in global sea level rise.
A time-mean Dynamic Ocean Topographic, and derived geostrophic velocities, computed from the latest Mean Sea Surface and Geoid models, have been added.
