A research team from Wisconsin has released a video recording four months of activity on the lake bed of Lake Michigan. Spoiler Alert: lots of fish make a cameo appearance.

Researchers at the University of Wisconsin-Milwaukee placed the camera on a lake bed thirty feet under Lake Michigan and set it to snap a photo every hour for four months. The result is a time lapse video condensing the four months into three minutes. The footage is from June to September 2015.

The University said the video helped them track the growth of algae on the lake bed, which has been a problem on several of the Great Lakes recently. They have also used the videos to study botulism problems among certain fish breeds and keeping track of plankton, the lowest form of life on the lake's food chain.

This footage was from a camera placed off the coast of Shorewood, WI by the University's Bootsma Lab. Other cameras have been placed off shore from the Sleeping Bear Dunes in Michigan.
