Assessing the completeness of the deglacial‐marine stratigraphic record on west Spitsbergen by accelerator mass spectrometry radiocarbon dating
The record of Quaternary glaciations of coastal areas is frequently preserved as a raised deglacial‐emergence sequence. Detailed radiocarbon dating of foraminifera and marine macrofossils from a representative deglacial sequence on west Spitsbergen document two periods of sedimentation at c . 11,400...
