On the significance of nitrification within the euphotic zone of the subpolar North Atlantic (Iceland basin) during summer 2007
The oxidation of ammonium to nitrite was investigated within surface waters (< 125 m) of the sub-polar North Atlantic (~ 60°N, 20°W) during late summer 2007. Sampling occurred within a mesoscale eddy dipole system and a definite bias towards waters beneath the euphotic zone as the focus for nitri...
