Summary
The 10- year average δ18O records from the (A) NIF2 and (C) NIF3 cores are shown for their entire lengths. (B) NIF2 depths are rescaled to the NIF3 depth scale by matching similar δ18O features, showing that NIF2 is contemporaneous with the upper 32 m of NIF3. The δ18O events labeled 1 to 9 are assumed to be coeval.
