Fig. 2: Sampling locations and temporal coverage of the Yamal7k tree-ring chronology.
From: Current Siberian heating is unprecedented during the past seven millennia
a Sampling locations and age class of the Yamal7k tree-ring chronology with indications of the four low-flow rivers. b Temporal distribution of 1611 individual series (1425 subfossil logs and 186 increment cores from living trees) color coded by the corresponding river. The mean segment length is 142 years (ranging from 41 to 452). c Ring age distribution across millennia.
