The Bosporus Sea in Turkey has attracted worldwide attention recently because of its color, which has turned from an almost dark color to an opaque tone of light blue. According to NASA, the color is caused by an unlikely growth of phytoplanktons in the water.

The Bosporus Sea changing its color is not surprising among residents in the area. Berat Haznedaroglu, an environmental engineer at the Institute of Environmental Sciences at Istanbul’s public Bogazici University, explained that this is an annual event that occurs after heavy rains washed nutrients from the Saharan desert into the Black Sea. These nutrients provided the right environment for the phytoplanktons to grow.

The result of these phytoplankton blooms dramatically changes the color of the sea. And in terms of oddly colored bodies of water, the Bosporus Sea is not alone. Here are more of these unique water bodies found all over the world.
