halocline

They're filled with fresh water (though there are areas where the salt water comes in and creates a salt / fresh water interface called the halocline, which looks wicked cool.

Freshwater is stored in the surface and halocline layers of the marine Arctic.

Regionally, the effects of upwelling of halocline waters onto the shelf must also be considered.

Brine release during sea-ice formation increases the density of surface waters which then sink and are advected from the shelf to basin interiors, transporting CO2 into the halocline and deeper waters.

Furthermore, the role that lateral advection plays in establishing the underlying halocline structure of the Arctic Ocean must also be considered.

Waters below the halocline are modified Atlantic waters that flowed into the Arctic through Fram Strait and the Barents Sea.

Low salinity waters are added to the surface and halocline layers via precipitation and runoff, Pacific inflow via the Bering Strait, and the sea-ice distillation process.

The layer containing the greatest change in salinity is called the halocline.

In the Arctic Ocean, freshwater is stored within the various layers above and within the halocline, the latter serving as an extremely complex and poorly understood reservoir.
