Diagram of basic features of a typical OMZ, showing the zones of processes found to support anammox in the Peruvian upwelling zone (5). Denitrification is not shown because it was not significant in this system. The diagram shows how deep ocean water normally increases in oxygen concentration at depth (along with nitrate), but in this study the OMZ was underlain by sediments (cross-hatched area).
