the warmer, deeper levels into the sea ice, which has considerable effect on its thickness. About of steeply rising salinity and increasing temperature. This is the actual halocline. The deep layer with nearly constant salinity and slowly decreasing temperature. Other types of clines Thermocline – A cline based on difference in water temperature, Chemocline – A cline based on difference in water chemistry, Pycnocline – A cline based on difference in water density.
