冰川冰 一种具有塑性的、透明的浅蓝色多晶冰体。由粒雪经成冰作用而成。
随着大量的水通过蒸发被抽离,并以雪的形式沉淀形成冰川冰,海洋中氧同位素的比率就发生了变化。
The oxygen isotope ratio of the ocean changes as a great deal of water is withdrawn from it by evaporation and is precipitated as snow to form glacial ice.
随着时间的推移,压力的增加,再加上从上方重新冻结的融水,小冰原颗粒成为相互锁结的大晶体蓝色冰川冰。
With additional time, pressure, and refrozen meltwater from above, the small firn granules become larger, interlocked crystals of blue glacial ice.
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.
