WebJan 25, 2015 · At 8.7 cal. kyr BP glaciers terminated proximal to their present margins. During the mid-Holocene climate optimum some of the present-day ice caps were probably absent. Ice caps expanded after 6.0–5.0 cal. kyr BP, and most glaciers reached their Holocene maxima during the Little Ice Age (AD 1300–1900). Webdata used for the younger portion of Marine04, 0–10.5 cal kyr BP, are given in a companion paper by Reimer et al. (this issue). Because high-resolutio n marine data are lacking from 0 to 10.5 cal kyr BP, the calibration curve for surface mixed-layer mari ne samples, Marine04, is constructed over this period from tree-ring measurements (Figure 1).
