Color+of+the+ocean

The ocean appears to have 2 different colors most of the time blue and green.when it appears blue its because of the nitrogen in the water.Most people say that when the water is green its because its "dirty".Their actually correct because when the water is green it means theres alot of algae in the water.The color of the ocean water is also determined by the way it absorbs or reflects sunlight.Water absorbs must of the wavelenght,or colors, of visible light.Many substances and organisms can affect the color of the water. For example, phytoplankton (microscopic plants in the ocean thhat provide food to many organisms in the ocean).By studying the color of the ocean scientists can determine that the presence of phytoplankton.
