Not sure if it's the case here but typically a low o2 underwater environment means a high concentration of Hydrogen Sulfide. This can have corrosive effects on some scuba gear and generally makes visibility very poor. I've crossed through a H2S layer in a Mexican Cenote (fresh water on top, H2S in middle, Salt on bottom) it was only a few feet thick, it's not something I'd want to spend a lot of time in though. Even though you are on SCUBA you can still smell and taste it and it's not pleasant. |
