To improve the chronology of sediments containing information about Holocene ice shelf and oceanic dynamics in the vicinity of the Antarctic Peninsula, we compare bulk acid-insoluble radiocarbon dating to ramped pyrolysis 14C dating in a sediment core containing ample organic material. This core spa...
