What is a pycnocline?
Quick Answer
A pycnocline is a layer in the ocean where water density changes rapidly with depth, usually because of changes in temperature or salinity.
The Full Story
Because seawater density depends on temperature and salt content, oceans often have layers that resist mixing. The pycnocline can act as a barrier that separates surface waters from deeper water masses. It influences nutrient transport, oxygen distribution, and the movement of marine organisms. In many places, it overlaps with or sits near the thermocline, but the key feature is the density change rather than temperature alone.
