Massive 'sea' three times the volume of all the planet's oceans found close to earth's core

A massive 'sea' three times the volume of all the planet's oceans has been discovered deep beneath the Earth's surface and close to its core, scientists have said.

The water is hidden inside a blue rock that lies 700 kilometres underground in the mantle, the layer of hot rock between Earth's surface and its core.

The revelation may help explain where the world's seas came from.

It's a bit misleading to call it a "Sea"?

The "water" is locked up within rock and I first heard/read about it in connection with Meteorites by following up info from the programme "Meteorite Men".

It's been known about for quite a while it seems.
