剩余的积雪能够让雪集成堆，且由于多年的积雪形成的压力，剩余的积雪能够让掩埋的雪变成冰川冰，这些冰川冰的厚度足以使冰块流动。
A surplus allows snow to accumulate and for the pressure of snow accumulated over the years to transform buried snow into glacial ice with a depth great enough for the ice to flow.
冰山是由雪形成的冰架或冰川断裂而成，主要由淡水冰组成，一般漂浮在开阔海域。
Icebergs are large pieces of freshwater ice that break off snow-formed ice shelves or glaciers and float in open water.

Firn: granular partially consolidated snow that has passed through one summer melt season but is not yet glacial ice.
当多年降雪多于溶雪时，冰川就形成了。
Glaciers form when more snow falls than melts over a number of years.
冰川行走其中一个最大的危险是雪桥断裂，接着掉进冰裂缝。
One of the biggest hazards of glacier travel is breaking through a snow bridge and falling into a crevasse.
总的来说，当夏天融化的雪量比冬天的降雪量少时，冰川会增加。
Generally, glaciers grow when the amount of snow that melts in the summer is less than the amount that falls in the winter.
季节性雪盖和冰川是全球水循环中的重要成分，监测季节性雪覆盖的范围以及冰川的堆积和消融地带，对于理解全球水循环是十分必要的。
