yes but why is it clearer closer to the equator, and less clear the farther north or south you go?

We see the water great masses, seas, lakes, rivers, with colors: blue, green, gray, sometimes brownish. But if one picks up a pot of that water the aspect is not colored. So the color is an optical phenomenon that is observed only when a large volume of water is considered and it depends on several things:

-The water reflects the sky, so its color depends upon the sky colour at that time, and if it has white or grayish clouds.

-At other hand the water colour depends also from the material that is found mostly into the sea water. There is life there…animal and vegetal, a lot, included the phytoplankton, microscopic plants that either float or are suspended there. And of course there are dissolved and suspended also inorganic and organic matter coming from the sea floor and from rocks.

Color is the result of optical interactions from the incident solar light and the billions of microscopic particles present.When the light of the sun reaches the sea surface different phenomena happen, part is reflected, part is absorbed and some is scattered. These phenomena happens with the water itself, the dissolved organic and inorganic matter and the suspended particles.The colour of sea water depends upon the distribution of these facts.

It is blue for clear ocean water and shifts to darker for less transparent or more turbid waters, and depends also from the depth and transparency of the considered layer of water. And that colour can be seen from space! That is why our planet Earth is called the "blue planet".

maybe, but water itsef is inorganic matter so it's too general for this topic
