End-Permian ozone shield unaffected by|[nbsp]|oceanic hydrogen sulphide and methane|[nbsp]|releases

Abstract
Earth experienced repeated episodes of widespread surface and deep-ocean anoxia with a significant accumulation of sulphide-rich waters over the past two billion years. The resulting massive releases of hydrogen sulphide from the oceans, together with methane from the geosphere, have been suggested as a cause for mass extinctions through destruction of the ozone shield and a lethal accumulation of hydrogen sulphide at the surface.
