Extended Data Fig. 7: Assessment of ebullitive methane (CH4) emissions.
Simultaneous observations of diffusive and ebullitive emissions from GRiMeDB13 were measured simultaneously. (a) illustrates the overall magnitude of the emissions, with the density plots (dark and light blue) showing the distribution and dot plots showing each observation. The large black dot represents the median value (n = 296). (b) shows the relationship between diffusive and ebullitive emissions, where each site with more than one measurement has a unique categorical color (number of sites = 93). The solid line is a linear model fit (model fit and statistics reported in the upper left corner of the plot) with the shaded polygon representing the 95% prediction interval, and the dashed line represents the 1:1 ratio.
