We found that both the area of ice-bound ebullition-bubble clusters and the bubbling rates that generated the clusters were correlated with L-band single-polarized (HH) SAR (R2=0.70, p=0.002, n=10) and with the ‘‘roughness’’ component of a Pauli decomposition of L-band quad-polarized SAR (R2=0.77, p=0.001, n=10).  Results of this study indicate that analysis of L-band SAR backscatter […]

We used high-resolution (9—11’¯cm) snow-free aerial images of an interior Alaskan thermokarst lake acquired 2 and 4 days following freeze-up in 2011 and 2012, respectively, to detect and characterize methane ebullition seeps and to estimate whole-lake ebullition.
