1·Icebergs afloat today are made of snowflakes that have fallen over long ages of time.

今天漂浮在水面上的冰山由很多年前降落的雪花形成。

2·The Amery Ice Shelf appears to be uniquely suited to the production of green icebergs.

埃默里冰架似乎是唯一适合形成绿色冰山的地方。

3·Icebergs are ordinarily blue to white, although they sometimes appear dark or opaque because they carry gravel and bits of rock.

冰山一般是蓝色到白色，尽管有时因为携带了砾石和小岩石而变成黑色或者不透明。

4·Some scientists are examining the potential for harvesting icebergs from Antarctica, which is estimated to have the biggest reserves of fresh water on the planet.

一些科学家正在研究从南极洲收集冰山的可能性。据估计，南极洲拥有地球上最大的淡水储备。

5·However, travelers to Antarctica have repeatedly reported seeing green icebergs in the Weddell Sea and, more commonly, close to the Amery Ice Shelf in East Antarctica.

然而，去往南极洲的旅行者们一再宣称在威德尔海看见过绿冰山，并且在南极洲东部靠近美国冰架的地方更为常见。

6·At certain times, apparently, more icebergs from the Arctic Ocean in the far north were traveling south well into the North Atlantic before melting and shedding their sediment.

显然，在某些时候，来自北冰洋最北端的更多冰山赶在融化沉积前向南漂入北大西洋。

7·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。

8·Scientists have also scrutinised whether it's possible to preserve the ice sheets of Greenland with reinforced high-tension cables, preventing icebergs from moving into the sea.

科学家们还仔细研究了是否有可能用加固的高压电缆来保护格陵兰岛冰原，防止冰山流入大海。

9·Recent expeditions have taken ice samples from green icebergs and ice cores—vertical, cylindrical ice samples reaching down to great depths—from the glacial ice shelves along the Antarctic continent.

近代的探险队已经从绿色冰山和冰核中带回了一些冰块样本，这些样本呈垂直的圆柱状，是沿着南极洲大陆的冰川冰架从极深的位置中取出的。

10·It's below freezing and small icebergs are floating by.

气温在冰点以下，一座座小冰山正漂过。《柯林斯英汉双解大词典》
