The planktonic record exhibits millennial-scale sea surface temperature (SST) oscillations over the Holocene of ~0.5 °C while the benthic δ18Oc document ~0.10‰ millennial-scale changes of Upper Circumpolar Deep Water (UCDW), a water mass which outcrops in the Southern Ocean. Solar forcing as an explanation for millennial-scale SST variability requires (1) a large climate sensitivity and (2) a long 400-year delayed response, suggesting that if solar forcing is the cause of the variability, it would need to be considerably amplified by processes within the climate system at least at the core location. We also explore the possibility that SST variability arose from volcanic forcing using a simple red noise model. Our best estimates of volcanic forcing falls short of reproducing the amplitude of observed SST variations although it produces power at low-frequency similar to that observed in the MD81 record. Although we cannot totally discount the volcanic and solar forcing hypotheses, we are left to consider that the most plausible source for Holocene millennial-scale variability lies within the climate system itself. In particular, UCDW variability coincided with deep North Atlantic changes, indicating a role for the deep ocean in Holocene millennial-scale variability.","author":{"name":"Khider, D., C.S.

The data are analyzed to investigate millennial-scale variability in surface and deep water during the Holocene. The record is 10,000-year long. Oxygen and carbon isotopic analyses were performed at the University of Southern California. Isotopic values are reported in delta notation relative to the Vienna PeeBee Belemnite (VPDB) isotopic standard. The Mg/Ca analyses were performed at the University of Southern California. The 14C chemistry was performed at NOSAMS (WHOI) and the University of California Irvine. 14C dates were converted to calendar ages using the Marine09 calibration curve from Reimer et al. (2009). The foraminifera geochemistry was converted from the depth domain to the time domain by using a spline interpolation between 14C dates. Age model uncertainty was assessed through Monte-Carlo simulations.","version":"1.0","xmlId":"13818"}
