Solar forcing of Holocene droughts in a stalagmite record from West Virginia in east-central North America

Abstract

[1] Elevated Sr/Ca ratios and dC values in Holocene-age stalagmite BCC-002 from east-central North America record six centennial-scale droughts during the last five North Atlantic Ocean ice-rafted debris (IRD) episodes, previously ascribed to solar irradiance minima. Spectral and cross-spectral analyses of the multi-decadal resolution Sr/Ca and dC time… (More)
