Stalagmites

Pacing of Dansgaard-Oeschger (D-O) cycles in Sofular and comparison of stalagmite and ice core chronologies. Comparison of D-O pacing between: a) D-O cycles during the last glacial period, recorded in the Greenland ice core NGRIP (data from Rasmussen et al), the Sofular stacked record and a Speleothem Interstadial Onset Compilation (SIOC19) data set (data from Corrick et al) and b) D-O cycles of the penultimate glacial period, recorded in the synthetic…
