Transpolar flights from london to tokyo .

由伦敦至东京穿越极地的航班。

The end of the cold war , which opened the way for new transpolar routes overflying russia , along with the development of ultra long-haul aircraft , has created new opportunities for non-stop services between asia and north america .

冷战的结束打通了经过俄罗斯领空并飞跃北极的新航线，再加上超远程飞机的发展，这都为亚洲和北美洲间的直飞服务创造了新机会。

Vast currents and winds push the ice around the ocean , some of it remaining trapped in the huge beaufort gyre off the coast of alaska , where it ages and thickens , and some being spat out between greenland and siberia in the great transpolar drift stream .

巨大的洋流和风推动着冰层，有些冰块陷在阿拉斯加海岸附近的波佛特海游漩之中，并在此不断沉淀，变厚，有些冰层在巨大的穿越北极的洋流的作用下被冲到格陵兰岛与西伯利亚海岸之间。

This moved a lot of ice from the beaufort gyre , a revolving current in the western arctic , to the ocean 's other main current , the transpolar drift stream , which runs down the side of siberia .

因此一些冰山由“薄福环流漂”（它是位于北极的西北的一个旋转洋流）向海洋上的另一个主要洋流“穿越极点流”（它由西伯利亚流出）。
