On the limits of Antarctic and marine climate records synchronization: Lag estimates during marine isotopic stages 5d and 5c
International audience [1] North Atlantic sediment records (MD95-2042), Greenland (Greenland Ice Core Project (GRIP)) and Antarctica (Byrd and Vostok) ice core climate records have been synchronized over marine isotopic stage 3 (MIS 3) (64 to 24 kyr B.P.) (Shackleton et al., 2000). The resulting com...
