What is the mixed layer of ocean?

The mixed layer of the ocean is the upper layer where wind-driven turbulence and waves create a uniform temperature and salinity. Typically extending from the surface down to a depth of about 50 to 200 meters, it is influenced by solar heating and atmospheric conditions. This layer plays a crucial role in the exchange of gases, heat, and nutrients between the ocean and the atmosphere, significantly impacting marine ecosystems and climate. Below the mixed layer, water properties can change rapidly, leading to stratification.
