Ground-truthing Methane Ice Bubbles
On Lake Claudi in Bering Land Bridge National Preserve on the Seward Peninsula in Alaska in November 2008. Researchers cleared a large section of recently frozen lake where they suspected finding high concentrations of methane ebulition indicated by bubbles in the ice. They DGPSed all bubbling hotspots here and then hope to capture these patterns with satellite synthetic aperture radar in the next days.
