美国海岸警卫队称，墨西哥湾钻井火灾事故发生海域的原油泄露量是预想的五倍之多。

The us Coast Guard has said five times as much oil as previously thought is leaking from a well beneath where a rig sank in the Gulf of Mexico last week.

据官方估计，石油泄露和蔓延的速度达到每天6万桶，远远超过BP做出的估计，相当于每四天就达到一次埃克森-瓦尔迪兹号的泄漏量。

The authorities reckon that the oil may be flowing at a rate of 60, 000 barrels a day—far more than the company estimated, and the equivalent of an Exxon Valdez every four days.

这样今年的泄露事件就又增加了一次，记录量增加了三千七百万。

That will add one more breach and 37 million more records to this year's tally.
