Mass extinction in Sea caused by Redox Changes?
How most life on Earth went wiped out 250 million a long time back? Utilization of different sulfur isotopes to explore redox condition changes in the Panthalassic Ocean can help which contains ∼85– 90% of the contemporaneous worldwide sea. The S-isotopic inconsistencies from Canada and Japan give proof to the timing of the beginning of euxinia and mixing of sulfidic and oxic waters. Information recommends that shoaling of H2S-rich waters may have driven the mass extinction and postponed the recuperation of the marine biological system.
The investigation shows how ecological changes could have devastatingly affected Earth’s early biosphere. As in the Permian mass extinction, marine mass mortality was caused by the euxinic condition and might have the delayed recovery of about 8 myrs. Today, worldwide global warming and eutrophication are causing the development of sulfidic zones on present-day continental racks which may cause the threat of the indigenous marine life.
