Extended Data Fig. 3: Reconstructions of ACC strength variations based on magnetic grain size from the SAZ to PFZ in the Indian sector over the last glacial cycle.

a, ACC strength variations in the SAZ (MD00-2375G, eastern Kerguelen Plateau)14. b, ACC strength variations in the PFZ (SK200/22a, Crozet Plateau)78. c, ACC strength variations in the PFZ (MD11-3353, Kerguelen Plateau)26. d, Antarctic temperature record from the Dome Fuji ice core47. Increases in ARM/κ and SIRM/χ indicate smaller grain size and weaker ACC strength14,26,78.
