Where the Atlantic heat meets the Arctic cold

The ocean is not as endless as we often think it is. It is actually divided into different domains and regions, ranging from the freezing cold polar waters to the hot tropical regions.

Water, water everywhere on this blue planet. But there is also a dirtier side to the sea, because under the waves is solid (though often muddy) ground.
