Why does the color of sea water sometimes look not always blue?

Bobo.id – Guys, have you ever been on a trip to some beaches and noticed the difference in colors sea water?
For example, on the first beach you visit, the sea water is clear blue. However, on the second coast the sea water is colored gray murky.
Is this event natural to happen on Earth?
In fact, sometimes some of the beaches we visit are still close together coastline.
Well, this time we will find out the cause of the difference in the color of sea water according to science. Come on, see!
Earth’s Rotation
Did you know, the water in Earth’s oceans moves from west to east, as a result of the planet’s rotation.
Rotation is a condition when the earth rotates on its own axis, about once every 24 hours, or to be precise every 23 hours, 56 minutes and 4 seconds.
Earth has a circumference of 24,898 miles or 40,070 kilometers. That is, the Earth rotates 1,037 miles per hour.

Well, in this rotation occurs a phenomenon known as upwelling along certain coasts.
Upwelling i.e. warmer sea surface water will move to colder and deeper waters.
In the Pacific Ocean, this phenomenon causes the water to turn a brownish gray color.
However, in the waters of the Bahamas this phenomenon does not occur, because the waves are driven by coral reefs.
So that in the waters of the Bahamas, we can see the color of the sea which is always clear blue. However, this is not only the case in the Bahamas.
On the coasts off the Philippines and Hawaii, the sea is crystal clear despite the waves.
The clarity of the water in the region is due to what is in the ocean.
Something in the Ocean
The researchers found a surprising fact, that in fact the gray sea water is more rich in nutrients than the clear sea.
This is because the turbid sea water is inhabited by many marine organisms, such as phytoplankton and zooplankton.
Reported from I swim, plankton is a collection of small organisms that live on the surface of the water, such as lakes, rivers, and oceans.
Zooplankton refers to small animal organisms, while phytoplankton are plant-like.
In addition to plankton, sediments such as sand and rocks found in the sea make the color of seawater more turbid.
Sand as a small particle -shaped sediment is more likely to make water turbid, than large -sized rocks.
So, when we see a lot of large rocks on a beach, usually the water will be clearer.
So, the conclusion is not all turbid seawater indicates the dirty state of the sea.
