Figure 3

(a–d) Soil O2 concentrations within the U1 mofette. Measurements were performed at each intersection of the grid. O2 concentrations at four different soil depths are given: (a) 10 cm, (b) 20 cm, (c) 40 cm, and (d) 60 cm. The colour bar indicates the gas concentration ranges. Orientation of the site as in Figure 1(b). CO2 concentrations are given in %.
