For one thing,Okinawa's oceans are influenced by ocean currents.This is the reason why Okinawa flows from north to southThe warm Kuroshio Current (= Japan Current) flows....... The Kuroshio Current is poor in nutrients andPlankton is also low.The Kuroshio Current is the fastest current in the world. The Kuroshio Current is also very fast,The seawater is clear and not cloudy.The ocean of Okinawa is a very clear and transparent place. This is a major factor in the endless transparency of Okinawa's waters. Currents from the South China Sea also flow into the area.

Okinawa is one of the most tropical regions on earth, with warm weather throughout the year.Coral grows in abundance because of this warm climate.is used to create the beauty of the Okinawan sea.An indispensable presenceIt is.
Corals absorb carbon dioxide from the ocean and photosynthesize inside their bodies to, ,Minerals are released into the water along with oxygenThis is what keeps the seawater clean. This causes purification and keeps seawater clean.
Coral bodies are mainly calcareous. After death, they produce the beautiful colors of Okinawa's blue ocean.The calcareous material breaks up into white sand andThe bottom of the ocean floor.Reflects sunlight to create an emerald green color.The following is a list of the most common problems with the

Corals have an increased chance of bleaching as sea temperatures rise. However, they also have the potential for natural recovery under the influence of typhoons.Typhoons of moderate strength stir up the seawater, lowering the water temperature, and thick clouds block the strong sunlight.This will help to reduce the stress that the corals are undergoing. The stress that corals are under is then relieved,Possible to suppress bleaching phenomenonIt is.

summary
Have you been able to understand why the sea in Okinawa is said to be beautiful? The Kuroshio Current, with its low plankton content, increases transparency, coral, ilabucha, and sea cucumbers make the sea and sandy beaches clean, and the low seafloor allows sunlight to make the blue ocean visible.
Of course, one of the reasons is that many humans are trying to protect the beautiful ocean and are engaged in activities that contribute to environmental preservation. Unfortunately, I have seen littering by both Okinawans and tourists. Let's continue to do what we can do, starting with small things, to prevent littering in the ocean. Then, please enjoy your trip to Okinawa as much as you can!
