Oceans contain 99% of the living space on the planet, and humans have explored less than 10% of it.
Jupiter's largest moon, Ganymede, has a saltwater ocean buried under 95 miles (152 km) of ice which is 10 times deeper than our oceans (around 60 miles deep)
Gold is plentiful in the ocean --- It is estimated that the world's oceans contain 10 billion tons of gold.
1 nautical mile is equal to 1 minute of arc on the planet earth. So 60 nautical miles is equal to 1 degree of arc.
Antarctica has as much ice as the Atlantic Ocean has water.
Gravity overtakes buoyancy at around 20 metres underwater and you start falling towards the centre of the earth.
The ocean is a perrenial mystery --- We know more about the surface of the moon than we do about our oceans.
If we could harness just 0.1% of the ocean's tidal kinetic energy, we could meet the current global energy demand 5 times over.
The oceans are rather shallow. If the earth were the size of a classroom globe, they'd be less than a millimeter deep
Volcanos are mostly a water-centric phenomenon --- 90% of all volcanic activity occurs in the ocean
The ocean is home to an estimated 50-80% of all life on earth.
Earth's oceans were formed due to millions of years of nonstop rain.
The Earth's oceans formed after several hundred million years of constant rain.
10% of the oxygen we breathe comes from just one kind of bacteria in the ocean
The deepest place in the ocean is about seven miles deep.
A mile on the ocean and a mile on land are not the same distance.
