2022年10月18日 Thus, if denitrification and/or anammox became active at low‐oxygen concentrations, then the subsequent removal of fixed nitrogen through N 2 production would limit primary production and the carbon flux into OMZ waters, stabilizing oxygen to levels limiting N 2 loss. However, with the low rates of denitrification measured in OMZ waters,
