Why is the ocean blue, especially in the deeper area?
in the deeper portion, tne ocean turns blue, while if its near the shore, its color green, but when u looked down, at the bottom part, the sand is not color green but somewhat yellowish or white.
Answers:
Someone told me about this not so long ago.
Its where the Sun reflects on the water or something for the sea
and
its green nearer the sand.. cus the sands yellow the seas blue so both colours mix together to make green
(dont reli make sense)
because it is a reflection from the sky.
Reflection and refraction.

Water itself is very slightly blue in colour, but the colour is only noticeable in very large volumes of the liquid.
PS if you don't believe water is blue in colour:
http://en.wikipedia.org/wiki/water.
the ocean is only the reflection of the sky combined with the depth of the water and it's refaction.
Because if it was green you might think it was land! Actually it is a reflection of the sky.
This is because the colour of the sky is reflected onto the water. If you notice when it is downcast the ocean turns more of a gray colour. It is different shades of blue (or grey) depending on the depth of the water because the water bends the light in a similar way a prism does. Hope this helps and the following link should explain a bit better.
Sunlight is made up of all the colors of the rainbow: red, orange, yellow, green, blue, and violet. Some of the sunlight is reflected off the surface of the water, reflecting the color of the sky. Some of the sunlight penetrates the water and is scattered by ripples and particles in the water (this tinges the appearance of the ocean with the color of the particles). In deep water, much of the sunlight is scattered by the oxygen in the water, and this scatters more of the blue light.
Water absorbs more of the red light in sunlight; the water also enhances the scattering of blue light. Sir Chandrasekhar Venkata Raman (an Indian physicist) won the Nobel prize in 1930 for his work on light.
AHHHHH!!! These peope are wrong!! Yes the sky makes the water blue, but the reason it gets - greener - is because if you mix blue and yellow(sand) - you get !! GREEN!!
It is because of the sand and because there is less water to absorb the reflection.
Hope this answers your question..

Why is the ocean blue?The ocean often looks blue because sunlight shines on tiny particles suspended in the water. Along the shores of some areas, however, the water looks green because the blue water is mixed with yellow pigments present in floating plants.
Some oceans exhibit other colors:
The Black Sea looks black because it has little oxygen and a high concentration of hydrogen sulfide.
The Red Sea looks red because it contains seasonal blooms of algae that color the surface water red.
The Yellow Sea looks yellow because it contains a yellow mud carried into it by adjoining rivers.
Shallow & deep the actual water is clear the deeper you go the darker it becomes there are some places on this planet where the water is literally Crystal clear.
it all depends on the reflection and refraction of light and the depth of the sea.
The colour is green near the shores because sea plants grow in the presence of sunlight. All plants needs the sun to manufacture chlorophyl Since the sun cannot penetrate the depth of the ocean no plant grows hence the deep blue true colour of ocean mass.
The only green colour you see from space is vegetation.
The ocean is blue as it reflects the oxygen above it.
Oxygen is slightly blue in hue, and that is why the sky and the ocean appears to be blue.
Plankton, however, is green, and is the most abundant life-form in the sea.
It is green because of its chlorophyll.
If there is an abundance of plankton, then the sea may appear green, but as the sea is made up primarily from oxygen and hydrogen, it will normally appear to be blue.
Nice question. I find that water must be slightly blue anyway, and not because of the sky, because it looks blue in the bath. Also if you go to a swimming pool, the water is a darker blue in the deep end. that would also explain why shallow water on the beach looks green, because you can see the sand through it. thanks for that-just thinking about the ocean has made me feel relaxed! :)
the deeper the blue, the deeper the sea
I suppose its agile?
Water has no colour!
It is the reflex of the blue skies which makes it look blue and this will vary a lot according to the weather (making it darker or clearer), the amount of water (revealing its deeper or shallow because of the amount of light that goes through) and if its close to land (usually greener in the shores due to vegetation, ground reflection, shadows, etc.). It is also green near sand due to the coulour mix of sky blue with sand colour (blue+yellow+green).
So it's all about light and our Sun, Moon and sky.
Sea water is easier to reflect as it contains a lot of minerals as well!
because the algae gives the color
it is darker at out shore cos it is deeper and its light inshore cos its more shalow there for the sun bounces off the bottom makinf it lighter!
it looks bluer because thats were it is deeper. i think it may b the refelction of the sky ? or that the sky is ble because of the sea ? not sure ?
It look's blue because it is reflected the colour of the sky. Looks greenish nearer the shore because the colour of sand below the water also affects it.
I think the deeper part of the ocean reflects the sky and the more shallow the algae or oceanic vegetation. Does this make sens.
thats because the sun is yellow water is blue so mix em up you get green, the deeper you go the less sun gets through so the water is bluer.
Its to do with the level of Calcium Carbonate or Limestone within the water, the presence of changes the colour which is why sometimes near the beach it looks dark blue and others greenish. The calcium carbonate generally comes from reefs and small shelled creatures in the water, or even the sediment itself. the water then has lots of CaCO3 dissolved in it. When the sun beats down onto the sea it causes a reaction which changes the hue to the next level which is green causing the difference in colour, and why you see a sharp change from greeny to blue not a gradual one like you see in the swimming baths
Green sea is found nearer the shore and is caused by the algae and other microscopic plankton feeding on the nutrients washing off the shore
Blue sea (pelagic or deep water) is further away from the shore and is usually devoid of such nutrients and hence doesn't go green
Although you do get algal blooms in some deep seas, these are caused by freak conditions
