Figure 4. Seasonal depth-cross sections of p CO2,
CH4, CT, N2O,
temperature and oxygen off Walvis Bay 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.
