Ice segregation and gas distribution in permafrost using tomodensitometric analysis
Abstract Ice lenses, soil layers, faults, sedimentary structures and gas bubbles in permafrost cores were imaged using a computed tomography scanner. Two kinds of images were produced: two‐dimensional sections which allow ice, gases and soil volumetric contents to be measured, and virtual three‐dime...
