  • Scientists have discovered a sixth ocean at approximately 700 kilometres beneath the Earth's surface.
  • This ocean is three times larger than all surface oceans combined.
  • This pool of water is trapped within a blue rock formation known as ringwoodite, situated deep within the Earth’s mantle.
  • However, the water reservoir is not an ocean in the traditional sense.
  • They are water molecules trapped within the crystal structure of ringwoodite.
