what is a halocline
In oceanography, a halocline (from Greek hals, halo- âsaltâ and klinein âto slopeâ) is a subtype of chemocline caused by a strong, vertical salinity gradient within a body of water.Because salinity (in concert with temperature) affects the density of seawater, it can play a role in its vertical stratification.n certain high latitude regions (such as the Arctic Ocean, Bering Sea, and the Southern Ocean) the surface waters are actually colder than the deep waters and the halocline is responsible for maintaining water column stability-isolating the surface waters from the deep waters.
