Definition
Eutrophic events refer to situations where bodies of water become excessively rich in nutrients, leading to an overgrowth of algae and other aquatic plants. This excessive growth can deplete oxygen levels in the water and harm aquatic life.
A condition where there is low oxygen concentration in a body of water, often caused by eutrophication. It can lead to fish kills and other negative impacts on aquatic organisms.
Nutrient Runoff: The movement of excess nutrients (such as fertilizers) from land into bodies of water through rainfall or irrigation systems. It contributes to eutrophication.
