Nitrogen Fixation in Denitrified Marine Waters
Figure 3
Nitrogen fixation rates of cruises Knorr 2007 and Galathea-3 2007.
The nitrogen fixation data gathered for northern Chile and Peruvian upwelling in 2005 (Knorr cruise, green circles) and 2007 (Galathea 3 expedition, red circles) is plotted against potential density from surface oxic layer to the core of the Oxygen Minimum Zone.
