I need some help with one observation of mine. I observed a pool of water full with algal blooms. The algal blooms of the pond appeared red in the afternoon but in the evening it turned green. What could be the possible reason behind this?
Thanks and regards
In the afternoon, the sun is shinning and therefore the tide is away and the depth is low, but during evening the tide is back and the depth is high hence the colour becomes green.
Kiprotich Kiptum Thank you but it wasn't observed in a sea. It was observed in a small pool of water accumulated nearby a dried river.
There is probably a problem with the oxygen content in the water or the transformation of chemicals in the algae, due to the light
Some green microalgae species have the protective red carotenoid for high light intensity during daytime (sometimes because of the nutrients content in water like salinity increasing when evaporation take place). When the microalgae get into the ideal condition, they will be in healthy green colour again.
