"The Pit is an incredible dive site in Tulum Mexico. A fresh water sinkhole with unlimited visibility a hydrogen sulfide layer (aka 'the cloud') and an 'island' of debris (with it's own tree which you can see in the picture)" says photographer Tom St George.

Cenote El Pit by Tom St George The Pit is an incredible dive site in Tulum, Mexico. A fresh water sinkhole with unlimited visibility, a hydrogen sulfide layer (aka 'the cloud'),.

Hydrogen sulfide là hợp chất hóa học với công thức H2S. Đó là một loại khí không màu có mùi hôi đặc trưng của trứng thối. Nó rất độc, ăn mòn, và dễ cháy.

A hydrogen sulfide bloom (green) stretching for about 150km along the coast of Namibia. As oxygen-poor water reaches the coast, bacteria in the organic-matter rich sediment produce hydrogen sulfide which is toxic to fish. (The image is taken from a bird's eye view.)

The light green seen here along Namibia's coast is not from phytoplankton bloom, but from hydrogen sulfide emissions.

Hidden Underwater River Flowing Under the Ocean in Mexico.

This "underwater river" is actually a briny mix of salt water and hydrogen sulfide. It's much more dense than regular salt water, so it sinks to the bottom and forms a distinct separation that acts and flows like a river.

Underwater River in Mexico. You go for a scuba swim to find another separate aquatic feature under the surface. An entire underwater River!

https://flic.kr/p/VVBCnU | Thumb Paintpots (late afternoon, 1 June 2017) 1 | Mudpots, or paintpots, are rare hydrothermal features. At such sites, volcanic gases rise through “mud” - a thick slurry of hot, acidic water mixed with fine-grained clay minerals. The clay minerals formed by chemical decomposition of rhyolite lava flows by naturally-occurring sulfuric acid (H2SO4). The sulfuric acid is the result of oxidation of volcanic hydrogen sulfide gas (H2S). From boreal spring to boreal…

‘Marbling’ is a characteristic of postmortem decomposition associated with bacterial gas and swelling of the body.This feature is usually seen 24-36 hours after death depending on the environment and is indicative of early stages of decomposition. It is produced by hemolysis of blood in vessels with the reaction of hemoglobin and hydrogen sulfide and the development of greenish-black discoloration of the vessels.
