Comparison of ice discharge from higher elevation areas of the
entire Greenland Ice Sheet with total snow accumulation gives estimates
of ice thickening rates over the past few decades. On average, the
region has been in balance, but with thickening of 21 centimeters per
year in the southwest and thinning of 30 centimeters per year in the
southeast. The north of the ice sheet shows less variability, with
average thickening of 2 centimeters per year in the northeast and
thinning of about 5 centimeters per year in the northwest. These
results agree well with those from repeated altimeter surveys, except
in the extreme south, where we find substantially higher rates of both
thickening and thinning.
