The leading explanation for what happened at Occator is that it could have had, at least in the recent past, a reservoir
of salty water beneath it.
Not exact matches
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.
In 2005, NASA's Cassini spacecraft spied jets
of water ice and vapor erupting into space from fissures on Enceladus, evidence
of a
salty ocean
beneath the saturnian moon's placid icy surface.
In a bid to resolve this problem, Libya is spending billions
of dollars
of its oil revenues on the Great Manmade River project, which is pumping ancient «fossil»
waters from
beneath the Sahara and piping it hundreds
of kilometres north to farms on the coast, where aquifers have become exhausted and
salty.
The warm Atlantic
water was
saltier, and therefore heavier and subducted at depth and reached to the bottom, actually heating up
beneath a lid
of ice and melt
water, that prevented the release
of heat to the atmosphere.
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.
Beneath the hydrocarbon seas on the surface, under a shell
of water ice, lies
salty liquid
water.
For example, Cassini discovered that the Saturn satellite Enceladus is a mini-world
of active jets — geyser - like phenomena that blast out
water vapor and ice particles from the huge,
salty ocean that lies
beneath the moon's icy crust.
That creates a return flow
of warmer,
saltier water toward Antarctica, where it's eroding ice shelves from
beneath.»
KAMUELA, Hawaii — With data collected from the mighty W. M. Keck Observatory, California Institute
of Technology (Caltech) astronomer Mike Brown — known as the Pluto killer for discovering a Kuiper - belt object that led to the demotion
of Pluto from planetary status — and Kevin Hand from the Jet Propulsion Laboratory (JPL) have found the strongest evidence yet that
salty water from the vast liquid ocean
beneath Europa's frozen exterior actually makes its way to the surface.
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.
That creates a return flow
of warmer,
saltier water toward Antarctica, where it's eroding ice shelves from
