1·However, recently eyewitnesses say drift ice now melts in as little as one week.

然而目击者表示，流冰在短短一周内融化。

2·The second reason we're starting now is because of the drift ice which normally starts around April. If we start now, we're able to avoid that.

第二个原因是浮冰通常在四月左右开始漂移，如果现在开始，就能够避免这个问题。

3·The Arctic finally announced itself late the next evening, with a sssshhhhhhhh as the ship slicked through a sea suddenly turned viscous, followed by the first drift ice, thudding against the hull.

到次日晚上北极终于出现了，海面突然变得凶险起来，第一块浮冰向船壳飘来。

4·Along the east coast of the United States, the southernmost advance of this ice is recorded by the enormous sand and drift deposits of the terminal moraines that form Long Island and Cape Cod.

沿着美国东海岸，最南边的冰川运动被大量的沙子和终碛石的漂流沉积物（形成了长岛和科德角）所记录下来。

5·As geologists mapped glacial deposits in the late nineteenth century, they became aware that there were several layers of drift, the lower ones corresponding to earlier ice ages.

19世纪晚期，在地质学家对这些冰川沉积进行定位的时候，他们意识到有好几个漂流层，位置较低的对应的是更早的冰川期。

6·Once detached from the ice shelf, these bergs drift in the currents and wind systems surrounding Antarctica and can be found scattered among Antarctica's less colorful icebergs.

一旦与冰架脱离，这些冰山就会受到南极洲附近的洋流和季风系统的作用，并开始漂移。人们可以在南极洲较暗淡的冰山群中找到这些散落的冰山。

7·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.

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。

8·The jagged ramparts of the mainland and islands unsoiled by human footprints drift past, an endless drama wrought in ice and snow.

未被人类踏足的大陆和岛屿的粗糙的城墙在眼前漂过，一出永不落幕的戏剧在冰雪中生成。

9·This is because the top of the troposphere is normally very cold, causing ascending water vapour to freeze into ice crystals that drift and fall, rather than continuing up into the stratosphere.

这是因为对流层的顶端通常极其寒冷，上升的水蒸汽凝结成飘落而下的冰晶，而没有继续上升进入平流层。

10·Later that afternoon I went to another lecture, about ice, in all its varieties: frazil, grease, brash, shuga, pancake, white, drift, rafting and fast.

就在那个下午稍晚的时候，我参加了另外一个讲座，是有关冰的，讲到了冰的所有变种：结块的、滑溜的、碎片的、松软的、扁平的、白色的、流动的、漂流的和坚固的。
