The boundry between the surface water and deep water.

*boundary

We know that warm water stays atop cold water. In fact, the change in temperature is abrupt, not gradual. The warm water layer is almost uniform in temperature. So is the cold water layer below. The dividing interface---pycnoline---is where the temperature changes from warm to cold.

Answer 2

Pycnoline is a natural compound found in certain plant species, such as Gnetum species. It has been studied for its potential health benefits, including antioxidant properties and its ability to promote wound healing and collagen synthesis.
