How do lake turnover events mix the water in deep lakes?
Quick Answer
Lake turnover happens when surface water cools and becomes dense enough to sink, mixing the lake from top to bottom. This can redistribute oxygen and nutrients.
The Full Story
In many deep lakes, water layers form in warmer seasons, with lighter warm water on top and cooler water below. In autumn or spring, surface temperatures can change enough for the top layer to become denser and sink. This triggers turnover, which mixes oxygen, nutrients, and sediments throughout the lake. Turnover is important for lake ecosystems because it can refresh deep water with oxygen and bring nutrients upward.
