Much of the Uk sand comes from rocks most of which are brown or greyish and we have one of the highest tidal movements in the world plus strong winds as mentioned will churn up the sand, Coral seas tend to be clearer because the sand is made of coral and heavier.
Why are UK seas brown?
“The main reason is the sediment suspended in the water all the time, very common in shallow seas, and the huge amount of large shipping we have moving through it and stirring it up,” he said. “It doesn’t mean the water is ‘dirty’ but that is what gives it its colour.
Why is the UK sea so dirty?
Where, previously, untreated sewage and storm water were discharged a mile out to sea via a long sea outfall, now they frequently discharge untreated sewage directly onto beaches and into rivers around the UK.
Why is some ocean water clear and some murky?
While you might think pollution turns clear water murky, there’s usually a different explanation. Some beaches have crystal clear water while others are murky and gray. … That’s when the warmer surface temperatures of the ocean move further out to sea and are replaced with deeper, colder and more sediment-rich waters.
Why is British water so murky?
It could be pretty accurate, since the color of the sea depends largely on how many particles are in the water, so the more it is affected by car pollution, boat traffic, and other human activity, the more particles get into the water and change its hue, making it appear darker and murkier.

Why is the Atlantic Ocean not clear?
Nearly the entire volume of the Atlantic Ocean water is clear and essentially colorless (as is true of all oceans). In large areas, with the sun beaming down, it tends to look blue, due to the blue part of the sun’s spectrum being scattered back out while the red end of the spectrum tends to be absorbed.
Why is Cornwall sea so blue?
It shows large swathes of bright blue ocean all around Cornwall. NASA reports this might be due to an unexpectedly large and intense bloom of phytoplankton. Phytoplankton are microscopic plant-like organisms that live in water.
Why is the sea in Cornwall so clear?
Hannah continues: “The clarity and turquoise colour in west Cornwall compared to say the North Sea or Bristol Channel is also because of the heavy sand particles which sit on the seabed, and lack of sediment swirling around in the water column.”
Why is the water in Hawaii so blue?
The reason the ocean is blue is due to the absorption and scattering of light. The blue wavelengths of light are scattered, similar to the scattering of blue light in the sky but absorption is a much larger factor than scattering for the clear ocean water.

Why is Bahamas water so clear?
The reason that the water in the Bahamas and Hawaii is clearer than along the California coast is likely a combination of both of these factors: 1) the sediments in the Bahamas and Hawaii tend to be composed of heavier particles that are not as easily stirred up or suspended, and 2) there tends to be far less
Why are Indian beaches not blue?
The primary reason for not having clear blue water at Indian beaches is rivers, and the terrain on which those rivers run. You will see that all turquoise blue waters come from islands. Islands do not have rivers. Rivers bring in sediment and turbulence which keeps the sediments afloat.
