Biogeochemical sulfur cycle
WebIntroduction. The sulfur cycle transfers enormous amounts of this biologically important element through the atmosphere every year. Despite the size of natural reservoirs, human activities have had a remarkable effect on the sulfur cycle, perhaps most notably in the production of acid rain. The Earth's surface is a source of windblown dusts ... WebIn relation to the organic carbon cycle of the seabed and the contribution of methane, the paper discusses the global sulfur budget and the role of sulfate reduction for organic matter mineralisation in different depth regions of the ocean – from coast to deep sea. The published estimates of these parameters are evaluated and compared.
