From the universe it can be seen that the Black Sea has changed color.

From the past to the present, the Black Sea has always been dark green, now it has turned to turquoise. The most pronounced change can be observed in the waters experienced by Romania, Bulgaria and Ukraine.


Algae blooms make the Black Sea change color.

Scientists believe that this change is related to the ephemeral coccolithophores that are in bloom and produce a lot of calcium carbonate. It is white so it makes the Black Sea become "brighter" and turns from dark blue to turquoise. In addition, microorganisms that move through the seas along the current also create a giant whirlpool that is visible from outer space.

Black seawater is usually dark green.

This phenomenon is still happening every year but this year it has unusual signs. The strong blooms of algae can lead to a lack of oxygen in the water, thereby causing harm to the flora and fauna of the Black Sea.
