Cryptotephrochronology of the Eemian and the last interglacial-glacial transition in the North East Atlantic ArchiMer
Abbott, Peter M.; Austin, William E. N.; Davies, Siwan M.; Pearce, Nicholas J. G.; Hibbert, Fiona D..
The Eemian interglacial and the onset of the subsequent glacial period serve as the most recent analogue for the natural operation of the climate system during the current interglacial. Pronounced climatic oscillations occurred during this period, but their nature and pattern are poorly understood due to dating limitations and unknown phase relationships between different regions and archives. Tephrochronology offers considerable potential for precise correlation of disparate palaeoclimatic archives preserving evidence of these rapid climatic transitions through the tracing of common isochronous tephra horizons. We outline the identification of three previously unknown cryptotephra horizons within a marine core from the Rockall Trough, North East Atlantic....
