Climate-induced speleothem radiocarbon variability on Socotra Island from the Last Glacial Maximum to the Younger Dryas

Steffen Therre et al.

Data sets

U-series and radiocarbon dating results of stalagmite M1-5 from Moomi Cave, Socotra Island S. Therre, J. Fohlmeister, D. Fleitmann, A. Matter, S. J. Burns, J. Arps, A. Schröder-Ritzrau, R. Friedrich, and N. Frank

Short summary
The radiocarbon (14C) levels of a stalagmite (grown 27–11 kyr before today) from Socotra Island (Arabian Sea) show drastic changes across the last termination. Our study highlights the influence of a warming climate with increasing precipitation towards the ending glacial on stalagmite 14C. High-resolution measurements suggest 14C is linked to a denser vegetation coverage on the island. Therefore, stalagmite 14C can be used as a climate tracer on millennial to sub-centennial timescales.
