The hydrogen sulfide contamination of the oceans and the seas is exemplified by the research of oil and gas content of the Black Sea Region. This kind of Black Sea contamination is the biggest in the world. Similar contamination is discovered at the Carnaco Sea Depression (the Caribbean Sea) situated in the hydrogen sulfide belt of the planet. So far only some branches of this belt (the Black Sea, the Caspian Sea, the Kotland Depression in the Baltic Sea, the Norwegian Fjords, etc.) are researched. The hydrogen sulfide contamination is related with the El NiГ±o event that means changes in temperature, pressure, and chemical composition of the oceans and the atmosphere. This event is lethal for fish. The El Nino event happens in the mobile parts of the world rift system (the East Pacific Uplift). A similar situation is observed at other hot spots of the planet (the South Kuril Islands, Iceland, the Hawaiian Islands, the Red Sea, etc.) where the centers of the hydrogen methane degassing are located. An increase of seismic activity, the gas bubbling, and sulfurous smell are observed in other parts of the planet during the El NiГ±o event. The rift zones of the mid-oceanic ridges are the main areas of the degassing. The hydrogen sulfide contamination of the Black Sea is caused by the weak movement of water through the Bosporus Strait, but the main reason for it is the degassing of the Earth. Distribution of the hydrogen sulfide is correlated with the relief of the sea bottom and is related not only with the convection near the bottom, but also with the hydrogen sulfide seeping through fractures.
