An intermediate layer of oceanic water in which salinity increases more rapidly with depth than in the layers above and below it.


(Physical Geography) geography a marked increase in the salinity level of the sea at a specific depth

Jamaica Bay has an overall residence time of ~35 days with no strong halocline (Benotti et al.
Possible consequences of this relocation range from major variations in the halocline depth in the Baltic Sea (Vali et al.
Surface waters were strongly stratified throughout the study, with a distinct thermocline, halocline, and pycnocline present in the upper 20 m (Fig.

The objectives of the buoy program are three-fold: 1) monitor the upper ocean heat content and ocean-to-ice fluxes; 2) quantify entrainment rates of heat that result from temporal and spatial variability in both the structure of the Arctic halocline and the strength of turbulent mixing mechanisms; and 3) test and improve parameterizations of ocean-to-ice fluxes for use in Pan-Arctic scale modeling efforts.

They create a layer known as a halocline (from the Greek words for "salt" and "slope").
Below that, the instruments would pass through a layer called the halocline, where the water remains cold but grows saltier with depth.
During the first 2 mo of sampling (March and April), the water column was relatively well mixed, with the exception of 2 wk in late March when a weak thermocline and halocline were detected followed by a mixing event (Fig.
