Evaluating possible sources of error in tree-ring 14C data using multiple trees across South America
A limitation in fine-tuned tree-ring radiocarbon ( 14 C) data is normally associated with overall data uncertainty. Tree-ring 14 C data variance as a result of sample heterogeneity can be reduced by adopting best practices at the time of sample collection and subsequent preparation and analysis. Variance-reduction of 14 C data was achieved by meticulous sample handling during increment core or cross-sectional cuttings, in-laboratory wood reductio…
Meteorological Factors Associated With Frost Rings in Rocky Mountain Bristlecone Pine at Mt. Goliath, Colorado
The meteorological factors involved in the formation of earlywood frost rings in Rocky Mountain bristlecone pine (Pinus aristata) have not been described in detail. This study used 51 tree-ring dated Rocky Mountain bristlecone pine trees growing at ca. 3500 m a.s.l. on Mt. Goliath, Colorado, to develop earlywood and latewood frost ring chronologies dating from 1930 to 2010 for investigation of the regional and large-scale weather anomalies respon…
Annually Verified Growth of Cedrela Fissilis from Central Brazil
Given the difficulty in obtaining robust chronologies from tree rings in tropical regions, the search for appropriate species is very important. Both dendrochronology and radiocarbon ( 14 C) measurements are required to validate the use of any specific tree. Some species have proved to be reliable for representing atmospheric 14 C concentration over time, such as Cedrela fissilis and Araucaria angustifolia . However, not only the species have to …
