Definitions:

Thermal Stratification

The layering of water in a lake or ocean, based on temperature variations with depth, which can affect aquatic life and water quality.

Spring Turnovers

Fall Turnovers

The annual mixing of lake waters driven by temperature changes, encouraging nutrient redistribution and oxygen circulation.

Aquatic Organisms
