1·But over the past decade, scientists in Italy and Denmark sent three expeditions to fetch samples from sediment in what's known as a deep hypersaline anoxic basin in the Mediterranean.
但在过去的十年当中，意大利和丹麦的科学家派出过三组探险队前往地中海，从地中海盆地那众所周知的高盐缺氧沉积物中采集样本。
2·If that is the case, the species was able to adapt from anoxic, or oxygen depleted, environments to an era of oxygenated oceans.
如果这个理论成立，意味着这种细菌能够适应从缺氧到含氧的海洋环境。
3·But when massive volcanism delivered more, it changed the amount of phosphorous available, and drove these anoxic events.
但是，当大规模的火山作用向海洋输送了更多磷时，就改变了可用的磷数量，从而导致那些缺氧事件。
4·Give them a huge oil blowout, and they can use up enough oxygen to create anoxic "dead zones" that imperil fish and other sea creatures.
在如此大量的原油泄漏的情况下，它们足可以消耗尽某一区域所有的氧气并创造出一个缺氧的“死亡地带”，这将危及鱼类和其他海洋生物。
5·However, the new study poses an alternative theory, that a build-up of sulphur in the half million years before the so-called Ocean Anoxic Event that occurred 94.5.
然而，这项新的研究推出的另一种理论指出，其责任在于发生在9450万年以前所谓海洋缺氧事件之前五十万年间的硫磺的累积。
