From: Olive shrub buried on Therasia supports a mid-16th century BCE date for the Thera eruption
Calibrated dating possibilities for the separate stems of the Therasia olive compared with the Santorini olive (a), modelled as a simple ordered sequence (see12) relative to IntCal2016 using Oxcal18 v4.4.4. 72-2 (b, c) and 88-2 (d, e) had the clearest growth boundaries so are shown as both an ordered sequence and a V-sequence at 25% uncertainty. 88-2 had an intact outer-most edge with bark which was also dated and is included in (d) and (f). 88-3, the small shoot is shown as (g), noting that the band count between samples in this case was very few. The changes in probability distribution using the juniper-based offset correction are shown with a red dotted outline. Grey vertical lines indicate current key volcanic sulfate layers in the Greenland ice31.
