Short summary

Sapropels are layers of sediment that regularly occur in the Mediterranean. They indicate periods when the Mediterranean Sea water contained no oxygen, a gas vital for most large organisms. This research investigated a key process in the nitrogen cycle (anaerobic ammonium oxidation, anammox), which removes nitrogen – an important nutrient to algae – from the water, during sapropel events. Using lipids to trace this process, we found that anammox was active during the no-oxygen times.
