Accumulation of snow and ice over time result in ice sheet layers. These can be remotely sensed where there is a contrast in\udelectromagnetic properties, which reflect variations of the ice density, acidity and fabric orientation. Internal ice layers are assumed to\udbe isochronous, deep beneath the ice surface, and parallel to the direction of ice flow. The distribution of internal layers is related to\udice sheet dynamics, such as the basal melt rate, basal elevation variation and changes in ice flow mode, which are important parameters\udto model the ice sheet. Radar echo sounder is an effective instrument used to study the sedimentology of the Earth and planets. Ice\udPenetrating Radar (IPR) is specific kind of radar echo sounder, which extends studies of ice sheets from surface to subsurface to deep\udinternal ice sheets depending on the frequency utilised. In this study, we examine a study site where folded ice occurs in the internal\udice sheet south of the North Greenland Eemian ice drilling (NEEM) station, where two intersected radar echograms acquired by the\udMulti-channel Coherent Radar Depth Sounder (MCoRDS) employed in the NASA’s Operation IceBridge (OIB) mission imaged this\udfolded ice. We propose a slice processing flow based on a Radon Transform to trace and extract these two sets of curved ice sheet\udlayers, which can then be viewed in 3-D, demonstrating the 3-D structure of the ice folds
