Radiocarbon Variability in the Western North Atlantic During the Last Deglaciation
We present a detailed history of glacial to Holocene radiocarbon in the deep western North Atlantic from deep-sea corals and paired benthic-planktonic foraminifera. The deglaciation is marked by switches between radiocarbon-enriched and-depleted waters, leading to large radiocarbon gradients in the...
