For an ice sheet to have constant size, the mass of ice added from snowfall must
equal the mass lost due to melting and calving (when icebergs break off).

The team found that, for the last 20 years, the glacier and ice cap
mass loss has been exactly
equal to the amount of meltwater runoff
lost to the sea.
Every year, TX Cam, a star in the late stages of its lifetime,
loses mass equal to one - third that of the Earth.
In the center, where it is very cold, they gain
mass, while around the edges they
lose an
equal amount.
So long as an ice sheet gains an
equal mass through snowfall as it
loses through melt, ablation, and calving from glaciers and ice shelves, it is said to be in balance.

losing a
mass equal to the Earth every 150 million years, or conversely providing a mechanism to double Earth radius in the past 250 million years.»
When these factors are
equal, the
mass budget is balanced, but for years the Greenland Ice Sheet has had a negative
mass budget, meaning the ice sheet is
losing mass overall.
