Ice-free lagoon sediment in areas of continuous Arctic permafrost revealed through electrical resistivity imaging ...
The Arctic is undergoing profound changes due to amplification of global warming in northern latitudes. One of the key features in the Arctic that remains understudied is ice-bonded subsea permafrost. This coastal feature is assumed to be ice-rich and underlies the many coastal lagoons in the Arctic...

The Arctic is undergoing profound changes due to amplification of global warming in northern latitudes. One of the key features in the Arctic that remains understudied is ice-bonded subsea permafrost. This coastal feature is assumed to be ice-rich and underlies the many coastal lagoons in the Arctic. Subsea permafrost, is estimated to store as much organic carbon as Earth’s atmosphere and protects Arctic coastlines from erosion. However, subsea frozen sediment near the shoreline has not been thoroughly mapped and how much thawed sediment exists beneath coastal lagoons remains unclear. The presence or absence of ice beneath the surface, and its thawing are vital information that potentially represent a positive carbon feedback to the global climate system. Through modeling and direct observations of electrical resistivity across a lagoon on the Alaska Beaufort Sea coast during the summer, we found that the subsurface is ice-free down to at least 17 m under the lagoon and down to 22 m at the beach.
