Cross-section of groundwater sampling locations; dissolved oxygen, and CH4 concentrations for each class are given in Table 1; see Walker et al. (2003) and Pint et al. (2003) for a thorough description of groundwater flowpaths in this catchment.
gcb12614-sup-0002-FigS2.pdfapplication/PDF15KFigure S2. Time series subset of ebullition rates from three traps compared to atmospheric pressure (AtmP, gray line).
gcb12614-sup-0003-FigS3.pdfapplication/PDF192KFigure S3. Correlogram for all 30 bubble traps (in ascending order) from the Allequash Creek transect; lower left panel: the blue color indicates significant positive correlation between traps with darker shading indicating greater correlation coefficients; upper right panel: a secondary visualization of the correlations, blue color also indicates positive correlation, and the correlation coefficient corresponds to the area of the filled pie.
