Fig. 2. Water isotope and dust flux records from Dome Fuji and Dome C in the oldest glacial period (MIS 16).

(A) δD record from Dome C core (19). (B) δ¹⁸O record from DF2 core (this study). (C) Dome Fuji dust flux (this study). (D) EDC dust flux (17). Black arrows indicate nine millennial-scale AIMs identified in low-pass filtered isotopic curve (Fig. 1F). Dotted arrows indicate small AIMs visible in the high-resolution data. All records are on the AICC2012 age scale.
