STEROIDAL alcohols (sterols) are fundamental biochemicals in eukaryotes and are indicators of organic matter sources and transformations in sea water and sediments1–3. Reduction of Δ5-stenols, the predominant biogenic sterols, to 5α(H)-stanoIs is primarily an anaerobic microbial transformation4,5. Increased stanol/stenol ratios are used as evidence of this process, for example in Recent sediments where stanol/stenol ratios are higher at lower redox potential2,6–9. The oxic nature of sea water… CONTINUE READING
