  1. Mean ± standard deviation of nitrate diffusive fluxes (dNO3, mmolN m-2 d-1) calculated for the main open ocean biogeographical provinces defined in the Antarctic, Atlantic, Pacific and Indian oceans between 40° N–40° S by Longhurst34. Nitrate diffusive fluxes were calculated using the global model GM.
