Mandy Joye warns of danger of methane gas in Gulf oil plumes

EarthSky

Mandy Joye: The methane concentrations in these plumes are 100 to 10,000 times what you would normally see in Gulf of Mexico water.

曼迪?喬伊：墨西哥灣原油層甲烷氣體濃度是正常情況下的100到10000倍。

You are listening to University of Georgia oceanographer Mandy Joye.In June 2010, Joye returned from an emergency research expedition in the Gulf of Mexico following the Deepwater Horizon oil spill. She talked to EarthSky about the high concentrations of methane gas she discovered in oil plumes deep beneath the surface of the Gulf.

您聽到的是對喬治亞大學(xué)海洋學(xué)家曼迪?喬伊的采訪。2010年6月，喬伊從一個緊急調(diào)研專家組歸來，該小組是在“海岸地平線”油井發(fā)生泄漏后成立的。她告訴EarthSky，深海處的原油層已經(jīng)產(chǎn)生了高濃度的甲烷氣體。

Mandy Joye: And there’s also propane and butane, and gases that derive from the same processes that make the oil.

曼迪?喬伊：泄露的還有丙烷和丁烷等氣體，這些氣體是在石油鉆取過程中產(chǎn)生的。

Dr. Joye said there’s so much gas leaking into the Gulf that we might be looking at severe oxygen depletion in Gulf water. What happens, she explained, is that naturally occurring Gulf bacteria “eat up” the vast amounts of methane and other gases.

喬伊博士說，大量甲烷氣體泄露可能會造成墨西哥灣水域嚴(yán)重缺氧。她繼續(xù)解釋道，那些隨之而來的海灣微生物會“吃掉”大部分甲烷和各種其他氣體。

Mandy Joye: But in the process, they’re consuming molecular oxygen from the water. The reason that’s a problem is that, so then you could potentially have large volumes of water floating around in the deep part of Gulf of Mexico that don’t contain any oxygen.

曼迪?喬伊：在這個“吃掉”過程中，這些微生物會消耗海水中的氧分子，從而問題就產(chǎn)生了，因為這將導(dǎo)致墨西哥灣深海海域徹底斷氧。

Ocean life depends on oxygen. Oxygen depletion in the Gulf of Mexico, Joye said, means lost habitat for wildlife, and potentially long-term repercussions on local fishing.

喬伊說，海洋生物離不開氧氣，墨西哥灣的缺氧意味著該處的野生動物將失去棲息地，這可能會給該地區(qū)的水產(chǎn)業(yè)帶來長期深遠(yuǎn)的影響。

Mandy Joye: The degradation of this oil and gas has been injected into the middle of the Gulf of Mexico. It is going to cause the oxygen depletion in the water, there’s just no way around it.

曼迪?喬伊：墨西哥灣石油和天然氣泄露狀況的惡化將導(dǎo)致該水域氧氣耗竭，這是我們不得不面的問題。
