It is suggested in the lit that nitrate in upwelling ocean offshore of the Atacama is up to 10 mg/L, ~ 0.2 mM, one origin of desert nitrate deposits. This may be about the dissolved oxygen level in the deep current until it meets some organic nitrogen source and a passel of nitrifiers. So where are the latter? Do they live in filaments on the edge of the shelf?

Elio replies: Good question about the nitrifiers. I don't know and will try to find out.
