Although the researchers are not sure how bacteria detect airborne ammonia, they have some hypotheses about why bacteria produce slime in response to volatile ammonia.

Meaning on the bottom is mud, then a layer of something they presume to be oil, and on top of that a two-inch thick goop that Asper calls "slime snot," possibly made up of oil and bacteria.
这条纹状泥土底层是烂泥，其上一层科学家估计可能是原油。再往上(也就是最上面)是两英尺厚的粘稠物，Asper称其为——粘稠的鼻涕(译者注：看起来很恶心啊，这科学家幽默感不好啊)，这粘稠物极有可能是由原油和细菌组成的。
