In their book chapter in 2011 Gagen et al. (2011) highlighted the need for stable isotope dendroclimatology to move beyond studies that simply demonstrate ‘potential’. This symposium, more than a decade since this publication, will focus on dendrogeochemical studies that demonstrate that the field has moved beyond studies focused on ‘potential’. In particular, this session will strive to identify compelling new insights into unique aspect...

Solar Energetic Particle (SEP) events cause an increase in atmospheric radiocarbon (14C) concentration.14C spikes in 774-775 and 993-994 CE have been measured in numerous tree-ring chronologies worldwide. Two other 14C excursions, in 1052 and 1279 CE, have been reported from Northern Hemisphere tree-ring chronologies. A critical factor for SEP event detection is the resolution of the tree-ring samples. Annually resolved records required to detect these short-term excursions can be costly, ...
