Numerous studies carried out since the discovery of the ozone “hole” over the Antarctic continent have motivated photobiological research to determine the potential effects of increased solar ultraviolet radiation – UV-B (280-315 nm) on organisms and ecosystems. Since then, the amount of literature on UVR (280-400 nm) effects has increased a lot especially that concerned with the effects of UVR on photosynthesis of aquatic organisms. The studies have shown that UVR wavelengths – both UV-A (315-400 nm) and UV-B, even at their natural ambient levels, generally cause a reduction in photosynthetic rates, which in turn may reduce primary production of aquatic ecosystems. In fact, extensive research has been done in several aquatic ecosystems of the World, mainly in the Antarctic Ocean, to evaluate the overall impact of solar UVR on phytoplankton organisms. .
