Extended Data Fig. 1: Areal methane fluxes from continental shelf regions.
From: Half of global methane emissions come from highly variable aquatic ecosystem sources

Boxplot showing median, lower (Q1), upper (Q3) quartiles and 1.5 times the length of the interquartile range of diffusive methane fluxes in areas with natural gas seeps, estuarine plumes, upwelling areas and the remaining (other) continental shelves. Differences are statistically significant (Kruskal-Wallis test, p<0.0001).
