Anoxic event

Oceanic anoxic events or anoxic events (Anoxia conditions) refer to intervals in the Earth's past where portions of oceans become depleted in oxygen (O2) at depths over a large geographic area. During some of these events, euxinia develops - euxinia refers to anoxic waters that contain H2S hydrogen sulfide. Although anoxic events have not happened for millions of years, the geological record shows that they happened many times in the past. Anoxic events coincide with several mass extinctions and may contribute to these events. These mass extinctions include some that geobiologists use as time markers in biostratigraphic dating. It is believed oceanic anoxic events are strongly linked to slowing of ocean circulation, climatic warming and elevated levels of greenhouse gases. Enhanced volcanism (through the release of CO2 and other greenhouse gases) is the proposed central external trigger for the development of these events.
