n. calving
misc. ice calving
这是北极圈的裂冰季节。
周末期间，其余被抬升的冰在该湖35来最大的裂冰中脱离了冰川(下图)。
During the weekend, the rest of the uplifted ice broke away (bottom picture) in the biggest calving in the lake's 35-year history.
裂冰过程开始于本月初，大雨后终端面上涨约20至40米，使600米宽终端面的数百万吨冰升高。
The process began earlier this month when the terminal face rose 20m to 40m after heavy rain, which lifted millions of tonnes of ice from the water across the 600m width of the face.
