摘要

Highlights

? 5α(H)-stanol/Δ5-sterol ratios in marine sediments were measured using TMAH GC–MS.

? Millennial-scale marine OMZ fluctuation occurred during the last 40kyr.

? 24-Nordehydrocholestanol/24-nordehydrocholesterol records paleo-redox conditions.

? Diatomstanol/diatomsterol records paleo-redox conditions.

? Other ratios are confounded by stanol-creating organisms.
