An intermediate layer of oceanic water in which salinity increases more rapidly with depth than in the layers above and below it.
A level of marked change, esp. increase, in the salinity of seawater at a certain depth.
A relatively sharp discontinuity in ocean salinity at a particular depth. In general, water with a higher concentration of salinity sinks below water that is less saline; therefore, saltier haloclines lie below less salty ones. An exception is the surface halocline of the Arctic Ocean, which is both colder and more saline than the warmer Atlantic water beneath it and which protects the polar ice from melting from below.
Origin of halocline
- halo- + -cline
