Fig. 3: Anatomy of last deglaciation abrupt changes from an ice-core multi-tracer approach.
From: The anatomy of past abrupt warmings recorded in Greenland ice
Onset and endpoints (symbols) of the studied transitions (oblique lines) together with associated uncertainty intervals (horizontal shaded lines) found by the ramp-fitting analyses applied to NGRIP and NEEM ice-core tracers across the Holocene onset (a and b) and across the transition into GI-1e (c and d) in this study (circles), ref. 23 (triangles) and ref. 25 (squares). All timings are represented relative to the timing of the onset in the δ18O transition inferred in this study. The vertical amplitude between the onset and the end of each transition is the same for all tracers, it has been set arbitrarily and does not represent the true amplitude of change for each ice-core tracer.
