Comment:
Polymineral multi-grain aliquot equivalent dose measurements were determined on a Risø TL/OSL DA-15 with a machine source error of 0.087 Gy/sec.
# =The preferred age is the sample age that correlates to a paleo sea-level highstand. For Mt1, both samples correlate to highstands during MIS3, so the full range of ages is used.

18 AGEAgeka BPOnderdonk, NathanEstimatedGeocode – Preferred age is the best approximation of the terrace tread age. For sites where samples are in stratigraphic order, we use the higher, younger age. For sites where samples ages are inverted, we use the Bayesian-determined overlap in terrace ages. For sites Ft3, the preferred age is the Bayesian-determined overlap between the youngest luminescence date and the radiocarbon date from the same site.
