(super 14) C ages of a varved last glacial maximum section off Pakistan.
In a core off Pakistan, we obtained 38 (super 14) C analyses by accelerator mass spectrometry (AMS) from a 4.4-m-thick, expanded, annually-laminated Last Glacial Maximum (LGM) section, bracketed by bioturbated intervals ascribed to the Heinrich-1 (H1) and Heinrich-2 (H2) equivalent events (52 (super...
