The Biogeochemistry of Sulfur: A Foundational Guide

Sulfur is an essential element driving planetary function, yet its complex cycling across vast environmental reservoirs often remains a mystery. This course provides a comprehensive introduction to sulfur biogeochemistry, transforming complex environmental processes into clear, understandable concepts. You will gain a solid foundation in the major reservoirs, fluxes, and microbial drivers that control the global sulfur cycle. What you'll learn: * Understand the fundamental chemistry of sulfur compounds and their oxidation states in natural systems. * Trace the major pathways of the global sulfur cycle across the lithosphere, hydrosphere, and atmosphere. * Analyze the critical role of microorganisms in sulfur reduction and oxidation processes (microbial biogeochemistry). * Apply basic principles to interpret sulfur isotope data in environmental and geological samples. * Learn how human activities, such as pollution and industry, impact natural sulfur cycles and environmental health. The course begins by defining key terminology and chemical concepts before moving into detailed sections on the oceanic, atmospheric, and terrestrial sulfur reservoirs. You will then apply this knowledge through practical examples of sulfur cycling in contemporary ecosystems. This course is designed for absolute beginners interested in environmental science, geochemistry, or microbiology. No prior scientific background is required to start learning.
