Abstract

Autotrophic ammonium oxidation rates are highest (about 4 × 10^-8 mol 1^-1 d^-1 or 7.5 × 10^-13 mol cell^-1 d^-1) below the photic zone in the nitrite maximum layer in California coastal waters, with rates approaching zero at the surface. Cell numbers of ammonium-oxidizing bacteria, however, are approximately constant with depth (about 5 × 10⁴ cells 1^-1), indicating greatly enhanced oxidation rates per cell below the photic zone. Light intensity in the water column may control the depth and formation of the primary nitrite maximum in this coastal regime.
