Why is it that in some places the seawater is crystal clear?

Seawater is crystal clear because the part that you are looking at doesn't have any particulate matter suspended in it, like

Dirt, sand,
Human pollution
And all kinds of stuff.

Some places at sea are so clear, and so shallow that you can see all the way to the bottom. Some places in ports and some silt-bearing rivers are so murky, you can't see beyond the surface of the water.

It all depends on what is floating in the water.

Sincere regards,
Mike Stewart
