3. Seasonal depth-cross sections of p CO2,
CH4, CT, N2O,
temperature and oxygen off Kunene 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−1on 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.
