What is the thermocline?

ScienceOceanography

Quick Answer

The thermocline is a layer in a lake or ocean where temperature changes rapidly with depth.

The Full Story

The thermocline separates warmer surface water from colder deep water and is common in both oceans and large lakes. In summer, it can become especially strong as sunlight warms the upper layers while deeper water stays cold and dense. This boundary affects fish movement, nutrient mixing, and how oxygen is distributed in the water. In the oceans, the thermocline is an important part of seasonal and regional water structure.
