摘要
2004年,综合大洋钻探IODP302航次在北冰洋的深海钻探发现:五千万年前的北冰洋曾是个亚热带淡水湖泊,沉积物具有优越的生油条件。2007年俄罗斯"和平-1"号深潜器将俄国旗插到北极的4000m深海海底,引起了北冰洋资源归属的国际之争。这些"破冰之旅"的气候背景,是使得北冰洋海冰迅速减少的全球变暖,因此北极"西北航道"开启的前景逐渐逼近,北冰洋的国际竞争正在升温。
In 2004, Integrated Ocean Drilling Program Expedition 302 drilled in the deep-water Arctic Ocean and discovered that the Arctic Ocean was a fresh-water lake with a subtropical climate some 50 million years ago, and its deposits are highly promising in oil production. In 2007, the Russian mini-submarine ＂Mir-1＂ planted a Russian flag on the sea bed about 4 km below the North Pole, lead- ing to international competing claims over access to Arctic resources. Both the ＂ice-breaking expeditions＂ took place under the background of global warming when the Arctic sea-ice cover is rapidly reducing. As a result, the opening of the Northwest Passage is progressively approaching, heating up the international competition in the Arctic Ocean.
