Paper Number: SEG-2021-3583076
... Seismic reflection imaging of subsea permafrost is a challenging task due to the presence of multiple wave modes created by the high impedance contrast between water, unfrozen and frozen sediments. In particular, guided waves and free surface multiples overlap with primary reflections, hiding...

... Summary In arctic systems, subsurface flowpaths are usually limited to a shallow active layer of perennial thaw above permafrost. Here we use two techniques, electrical resistivity (ER) and depth-to-refusal frost probing, to estimate active layer thaw of arctic hillslopes in and around common...
