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•乔伊:墨西哥湾原油层甲烷气体浓度是正常情况下的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.

您听到的是对乔治亚大学海洋学家曼迪•乔伊的采访。2010年6月,乔伊从一个紧急调研专家组归来,该小组是在“海岸地平线”油井发生泄漏后成立的。她告诉EarthSky,深海处的原油层已经产生了高浓度的甲烷气体。

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

曼迪•乔伊:泄露的还有丙烷和丁烷等气体,这些气体是在石油钻取过程中产生的。

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.

乔伊博士说,大量甲烷气体泄露可能会造成墨西哥湾水域严重缺氧。她继续解释道,那些随之而来的海湾微生物会“吃掉”大部分甲烷和各种其他气体。

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•乔伊:在这个“吃掉”过程中,这些微生物会消耗海水中的氧分子,从而问题就产生了,因为这将导致墨西哥湾深海海域彻底断氧。

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.

乔伊说,海洋生物离不开氧气,墨西哥湾的缺氧意味着该处的野生动物将失去栖息地,这可能会给该地区的水产业带来长期深远的影响。

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•乔伊:墨西哥湾石油和天然气泄露状况的恶化将导致该水域氧气耗竭,这是我们不得不面的问题。
