Mofette Vegetation as an Indicator for Geogenic CO2 Emission: A Case Study on the Banks of the Laacher See Volcano, Vulkaneifel, Germany
(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 %.
