a–e Ice thickness modeled at 80, 65, 57, 35, and 21 ka by using the glacial index method based on \({{{{\rm{U}}}}}_{37}^{K}\). f–j Ice thickness modeled at 80, 65, 57, 35, and 21 ka by using the glacial index method based on \({{{{\rm{U}}}}}_{37}^{{K}^{{\prime} }}\). Those snapshots are chosen as representatives of the Marine Isotope Stage (MIS) 5, MIS4, early MIS3, MIS3-MIS2 transition, and Last Glacial Maximum, respectively. Both proxies, \({{{{\rm{U}}}}}_{37}^{K}\) and \({{{{\rm{U}}}}}_{37}^{{K}^{{\prime} }}\), were obtained from the offshore records MR16-09 PC039. PATICE geochronological reconstruction of the Patagonian Ice Sheet at 35 ka is shown in orange3. Red star indicates the position of the offshore records MR16-09 PC039.
