夏天冰化了，他们只好停下来。

In the summer the ice melted so they stopped their journey.

2003年整个夏季之中，上一个夏天冰架崩塌中残留的碎片逐渐分解，而这些冰山和更小冰块的混合物也开始渐渐漂走。

Throughout the summer of 2003, remaining fragments of the shelf broke away, and the melange of icebergs and smaller ice pieces from the previous summer's collapse began to drift away.

冰减少的越多，形成的无冰水面就会越多，这些无冰水面在夏天时的温度会持续升高，在冬天结的冰就会减少，来年夏天也会有更多的冰融化。

The more you lose, the more open water is created, the more warming goes on in that open water during the summer, the less ice forms in the winter, the more melt there is the following summer.
