Evaluate the drafted changes
The lead sentence sounds very cohesive but could be confusing to someone not familar with clines in general. I think putting a short description of a cline after the link to its Wikipedia page would be helpful in making sure readers have at least a vague idea of what the article includes from the first sentence. It could be as brief as describing it as a natural phenomenon where a layer of water has different chemical properties than the surrounding body of water. Since this article only has one section on the different types of chemoclines, it would be helpful to list and expand upon them to explain the variety of presentation and properties that can occur. Your work is well-written and clear, but some small notes I would make would be to fully write out "aerobic life is restricted to the region above the chemocline while anaerobic species reside below" or a similar phrase just to make the language formal throughout the article. Linking the anoxygenic photosynthesis Wikipedia page would also be a positive addition.

The article has a very natural flow with every paragraph introducing a concept explained by the following one. Your explanation of how a chemocline is formed and the required conditions is well done and is structured to be as easily understandable as possible. I also think it was a nice touch to add other facts about chemoclines at the end of the section so that readers can anticipate what content might be included in future sections should they be added to the article.

Admittedly, the content of this article is fairly limited. Of course, you're not to blame for that since the article was likely sparse to begin with, but any expansion on what's currently included would be a great improvement. For example, you mention a study that investigated green sulfur bacteria who lived exclusively in the chemocline. It would be interesting to see what organisms are commonly found in the different types of chemoclines and the roles they play in their respective ecosystems. Further explaining the role chemoclines themselves play in nature would be great. Besides simply wanting more, I was pleased with your balance of coverage since it gave a great introduction to your topic.

You did an awesome job maintaining a neutral tone throughout the draft and didn't include any biased information or partial conclusions. Your writing is matter-of-fact, clear, and to the point. The picture is a nice addition and same as your written additions doesn't have any agenda besides informing by providing a helpful visual example of what's described in the article.

The included reference sources are reliable, one from a scientific journal and another an encyclopedia. I doubt these cover the entire breadth of the topic of chemoclines but seem to be a solid foundation to be built upon by future expansion. The sources match the facts they're cited to in the article. Oddly, the "Meromictic Lakes" source link worked when I clicked on the DOI but resulted in a "page not found" error when I clicked on the title. Though these serve their purpose, I would recommend adding more recent sources since these are from before 2010 and could include some outdated information or make conclusions based on now disproved facts.
