Figure 5. Seasonal depth-cross sections of p CO2, CH4, CT, N2O, temperature and oxygen off Lüderitz in winter (panel A), autumn (panel B) and summer (panel C) with overlaid density. In order to preserve optimal resolution, we imposed an upper limit of 55 nmol L−1 on the highest CH4 concentrations and an upper limit of 45 nmol L−1 for the highest N2O concentrations. Sampling locations were represented by white circles.
