Planetary theorist David Stevenson of the California Institute of Technology in Pasadena agrees that the best explanation for the magnetic field data is a deep
layer of salty water.
One intriguing possibility: If fluid water does persist on Mars, life that might have thrived there millions of years ago, when the climate was warmer and wetter, could be hanging on in thin
layers of salty water just beneath the surface.

One last thing to remember is after cooling it down in the fridge the feta cheese will drip out some
of its
salty water, forming a
layer of liquid around the dip.
A very cold but relatively fresh
water layer covers a much warmer and
saltier water mass, thus acting as an insulating
layer,» explains Prof. Dr. Mojib Latif, head
of the Research Division at GEOMAR.
Part
of this phosphorus has been replaced by
saltier water and moved into the higher
water layers.
The results were encouraging: The new «sea
water» formed a
layer on top
of the even
saltier Dead Sea
water, and flowed back up into the simulated aquifer, effectively plugging it.
Beneath it lies another
layer of rock full
of ancient,
salty water, and the change in
water flow is allowing that to seep into the fresh
water above.
The ice shelf floats within a pool
of its own cold meltwater that sits atop a deeper,
saltier and warmer
layer; the two
layers generally don't mix, like oil and
water.
«So the best explanation is a region
of salty, liquid
water below the frozen surface, which supplies a conductive
layer.
At the mines,
salty water is diverted into pools and then dried up by the sun — what's left is a thin
layer of salt.
As a result, while a
layer of ice - cold fresh
water sits just beneath the sea ice, about 20 meters (65 feet) down there is a
layer of denser,
saltier water that has been gradually warmed by the sun's rays.
The authors postulated that this warm
salty water (WSW)
layer, situated beneath the colder surface freshwater in the North Atlantic, generated ocean convective available potential energy (OCAPE) over decades at the end
of HS1.
So, the
saltier and more dense Atlantic
water sinks below the surface and a colder fresher
layer of water above it acts as a insolation blanket that limits the amount
of ocean heat in contact with the ice above.
This makes it clear to what extent the variability in the inflow
of «warm and
salty» North Atlantic
water at times
of positive values
of the NAO (North Atlantic Oscillation) dominates the temperature
of the Atlantic
water mass by importing «vast quantities
of heat» into the Arctic Ocean to induce core temperatures in the intermediate
layer in Nansen Basin that are much warmer than in the Canadian Basin, far downstream.
Atlantic Meridional Overturning Circulation A major current in the Atlantic Ocean, characterized by a northward flow
of warm,
salty water in the upper
layers of the Atlantic, and a southward flow
of colder
water in the deep Atlantic.
