Why is the ocean bluer in the Caribbean?

There are many reasons, it may be how the light is hitting the sea, the color of the sand, pollution or lack thereof, coral reefs, currents, and many other reasons.  Here is a great link about why water appears blue.  This may help answer your question.

Hawaii has less pollution, better sea currents & tropical waters are generally clearer/bluer than temperate waters. There are parts of the world with nicer waters than Hawaii but in relation to California, that is how I'd best put it.

yea.\nwhy would you want to spend winter in the caribbean when its just as warm on the jersey shore?

it has maritime climate coz its an island - so not too hot or too cold. but being situated near the equator could also give i ta tropical climate

The seas, ocaena, rivers, and lakes of the world are all composed of similar material to different degrees. For example the Atlantic, Pacific and Indian Ocean all have different amounts of salt in them. When the Panama canal was built a division between the regions was seen. Not so much with eyes but with equipment. True, those who named regions of water may not have had any idea that they were slightly different but they are. On a ship it'll be pretty hard to tell which ocean you're in if you awoke from a concussion and just stared out at sea. Maritime borders are only used as a political tool. Every second some of teh ATlantic mixes with the Pacific and vice versa.

The answer is kind of complicated.  To explain it as simply as possible, it has to do with the fact that the Gulf Stream is just one part of an enormous, clockwise-spinning gyre in the North Atlantic that is powered by a combination of the Earth's rotation, interaction with semi-permanent high and low pressure regions, and surface winds.  The net effect is  to channel large of amounts of warm water northward in the  west Atlantic (as the Gulf Stream), and an equal amount of cool water south in the eastern Atlantic (as the Canary Current).

The water particles,mixed in the air ( sky ), are responsible for this.The sunlight is refracted by those water molecules and thus we see the colour of the sky as blue.As you may remember,in the rainbow colours,Blue comes just after Violet and Indigo which are not that prominent as Blue. \nThus we see the sky blue.

Insider Mole has a pretty good answer. You might add that, because the Atlantic is narrower, the effect of the Gulf Stream is more pronounced than the similar currents that move throughout the Pacific Ocean. I don't know for certain but that is what I would believe.

The sky usually is blue on certain days (eg. nice sunny days) before the clouds come and cover it up. When u are on an airplane and u go above the clouds, the sky is almost always blue (but I can only speak for Australian sky!)\n\nThe ocean reflects the colour of the sky usually so it can be a blue/green, but can also have kinda grey/brown tones due to dirt/pollution/weather conditions. \n\nAnd yes we are going to run out of oil one day.  I was asking someone about it the other day.  They said years and years ago they said that oil would run out in 10 years but it hasnt yet.  They also said it was predicted that it would run out in 2010 but i dont think it will.  There may be masses of undiscovered oil out there, who knows?  \n\nAnd as for the gas/fuel prices, my guess would be EXTREMLY high until no-one can afford to drive except the rich (like in the olden days!)

The most obvious answer is that it reflects the sky since you can see reflections of clouds also. But reflection is only part of the answer. \n\nIt is true that part of the light you see is a surface reflection of sky light. The amount of this sort of reflection, though, depends on a number of things such as your viewing angle. On the other hand, much of the color you see comes from the water's depths. \n\nWhite sunlight contains all colors. Water absorbs some of these colors more than others. But you need a lot of water to notice this effect - which is why water cupped in your hand has no color at all. In a large body of water though, the water molecules quickly absorb red light, but they don't absorb blue light nearly as well. So in this case, more blue light is transmitted through the water. It's actually the same principle behind why the sky is blue. \n\nThe blue effect is often increased because ocean and lake water usually contains floating particles of dirt, and dead and living plants and animals. They help reflect the blue light back upward - so that the lake or ocean looks blue. The blue-green of tropical waters is due entirely to absorption of red light rather then suspension of particles. It's a different blue than the blue of the oceans off the northeast coast, whose blue is caused by suspended particles and plants. \n\nSo now we know why some bodies of water appear blue, but what about the other water colors, like gray, brown and black? Different colors can be produced by specific things suspended in the water. Mud acts in the opposite way from water -- it reflects red light more than blue. So muddy water looks brown. Since rivers are big transporters of mud, they usually appear brown. Peat dissolved in water absorbs almost all the light that touches it - so a lake full of peat may look black. The ocean often usually looks gray on a stormy day. Partly, that's reflected gray sky - but it's also because clouds filter out a lot of the sun's red light before it ever reaches the water. \n\nColors of water can be pretty distinctive. The Black Sea is so named because of its color, a very dark almost black color. In this case, it's the almost constant fog over the Black Sea that absorbs incoming light and makes the sea appear black. It was enough to make the Turks and many other sailors want to avoid what they saw as an evil looking sea!

The ocean reflects the sky! The sky is blue because of the way light passes, and the ocean or any water mass outdoor reflects this light.

It's daytime, because of physics. \n\nTo make this simple, just think that since water takes longer to heat than the earth, the air over water is cooler than the air over land. There's some physics law that says everything will reach an equilibrium in temperature. So, the air above will ocean will be moving towards the land to try to equalize. \n\nIn contrast, at night, the air over land cools faster than the air over water. Thus, the breeze goes into the sea. \n\nGood luck!

the water, earth and moon are always moving......why is some water clear and some murky?  there are so many factors, bacteria in water don't live in warm water, so in tropical places the water is clear, on the other hand, places like east or west coast usa are colder so the water has a higher degree of pollution or looks more "murky"

Well the sea is blue because the blue light from the sun is refracted and the other channels of light get through.

Because the sea level in the pacific is different than the sea level in the atlantic. Rather than having fast rapids flowing from one side to the other (more erosion and harder for ships to navigate), they have level sections of water separated by locks.

no the sky is no actually blue, have you noticed that at night you can see space? well thats because during the day the sun ray that come through our hemisphere are hitting against the massive amount of Ocean on our Earth, they do not reflect, but instead refract off the water molecules and transmit into the air, shooting all the way back up to our hemisphere, this gives us the sight of a blue sky.
