A pycnocline is a sharp change in density with depth within a body of water. In freshwater environments such as lakes this density change is primarily caused by water temperature (thermocline), while in seawater environments such as oceans and estuaries, the rapid density change in the water column is often caused by a combination of decreasing water temperature and increasing salinity (halocline).
