Fig. 1: Revine Trees, location and chronologies.
From: Atmospheric radiocarbon levels were highly variable during the last deglaciation
A map showing the location of Revine (red square) (base map from GeoMappApp (www.geomapapp.org); B Revine trees collected in 1995 by B.K. field campaign (The photo is taken by B.K. co-author of the paper, and under his copyright); C Ring width index chronologies of Revine groups 1, 3, 2 and 4 on its relative Revine timescale. The relative positions resp. the approximately absolute ages of the tree-ring series are based on the Δ14C comparisons. Gr.1 and Gr.3 are matched dendrochronologically (tBaillie&Pilcher: 5,1). Gr. 2 and Gr. 4 overlap only very slightly and they do not show any obvious statistical significant match. Their tentative position is based on a multi-step argumentation line of Δ14C comparisons, 10Be-Δ14C comparisons and the statistically non-significant visual match of the tree-ring series.
