Images taken over the Barents Sea by one of NASA’s satellites in late August show huge areas of milky-blue color water, reports Discovery News. This is due to phytoplankton.
One litre of seawater can contain more than a billion phytoplankton cells and the plankton belt can cover thousands of square miles according to a NASA source reported by Discovery News.
Populations of these single-celled, plant-like organisms explode when there is an abundance of carbon dioxide in the water.
