All processes, which include snowfall, condensation, avalanching, snow transport by wind, and freezing of liquid water, that add snow or ice to a glacier, floating ice, or snow cover. The term also includes the amount of snow or other solid precipitation added to a glacier or snowfield by these processes.
although there is very little precipitation at Halley, large amounts of snow is blown onto the ice shelf. Items on the surface become buried and regularly have to be dug out and lifted onto the surface. There can be as much as two metres of accumulation in a year.

all processes by which snow or ice are added to a glacier. This is typically the accumulation of snow, which is slowly transformed into ice. Other accumulation processes can include avalanches, wind-deposited snow, and the freezing of rain within the snow pack.
The addition of ice and snow into a glacier system. This occurs through a variety of processes including precipitation, firnification, and wind transportation of snow into a glacier basin from an adjacent area.
the net gain in an ice mass. The sources of accumulation are direct snowfall and avalanching from higher slopes
