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.
From: Zonally asymmetric changes in the Antarctic Circumpolar Current strength over the past million years

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.
