There is a middle layer referred to as the ‘thermocline’ where a rapid temperature transition occurs. In the fall, turnover happens when the epilimnion cools and becomes denser. In the winter, ice cover on the top of Lake Michigan insulates the deeper water, which stays liquid. Turnover then occurs again in the spring when the top layer warms. The turnover and layering ensure that the lake stays oxygenated.<ref name=a/><br> | <br>Lake Michigan becomes stratified during the summer months. The lower layer stays cooler and denser.

Microbial Ecology of Lake Michigan
Overview
By David Pleta
Lake Michigan is one of the largest freshwater lakes in the world.[1] Its size makes it interesting area of study in terms of its microbial ecology. It can be seen as somewhere in the middle of the spectrum between highly productive small lakes and the oligotrophic ocean. Its importance to the surrounding communities also makes it an important area of study.

Overview of Microbial Ecology as it is known
Discuss the alpha and beta diversity of the system. Include some current research, with at least one figure showing data.
Expansion topic 1-3
How you expand upon the basics will depend on your environment. Pick a couple or three of interesting subtopics and describe them in detail. Include some current research, with at least one figure showing data.
Key Microbial Players
In all of your systems there will be at least a couple of key microbial players. Describe these in detail. Where do they fall on the tree of life? Are they cultured? What do they do in general and as it relates to your target environment?
Conclusion
