Tropical waters are nutrient poor at the surface. When living things die at the surface they sink to the bottom where they decompose. The nutrients that are released when they decompose stay at the bottom because there's a thermocline--the deep water is cold and the surface water is warm and they don't mix. So the surface waters don't have much algae and stay clearer.
in clear water
Cold water is murky because it is nutrient-rich. The nutrient-rich cold waters harbor the minerals that provide the food chain for marine life beginning with the phytoplanktons (microscopic plant-like organisms). The phytoplankton depend on the nutrients and minerals in cold water to live. Phytoplanktons are the beginning of the food chain for a majority of aquatic life. Phytoplankton in large numbers produce the green-color on the surface of colder waters. Tropical waters are warm and nutrient deficient. Tropical waters are essentially a desert sea. The lack of nutrients produces clear water. Also of note -- the lack of nutrients precludes the development of phytoplantons; therefore, tropical waters lack the abundance of marine life that colder waters provide. Tropical marine life primarily survive off the reefs.
The water is murky
what does murky water mean
Naturally the ocean is supposed to be clear. The blue is an illusion of the sky reflecting on the water. The color we see now is a mix of all the dirt,sand,slime, and seaweed at the bottom of the ocean.

A tropical coastal area. Hurricanes are tropical cyclones that form over warm ocean water.

No, "murky" means hard to see through. Deep water can be murky because it is often dark, but shallower water can also be murky if it is muddy.
