Belfast Radiocarbon Dates VI [PDF]
Radiocarbon, 1970 The dating equipment and operating conditions remain essentially as previously described. This list includes some small samples counted at a filling pressure equivalent to 76cm Hg. at 20°C. Carbon isotope ratios were obtained and calculated as described (R., 1973, v. 15, p. 212). All samples are from Ireland.

An Improved Method for Extracting, Sorting, and AMS Dating of Pollen Concentrates From Lake Sediment
Frontiers in Ecology and Evolution, 2021 High-resolution chronologies are crucial for paleoenvironmental reconstructions, and are particularly challenging for lacustrine records of terrestrial paleoclimate.

Is there any Evidence for Regional Atmospheric 14C Offsets in the Southern Hemisphere? [PDF]
, 2013 Center for Accelerator Mass Spectrometry (CAMS) Tasmanian huon pine (Lagarostrobos franklinii) decadal measurements for the interval AD 745–855 suggest a mean interhemispheric radiocarbon offset (20 ± 5 yr), which is considerably lower than the ...

Interactive Effects Determine Radiocarbon Abundance in Soil Fractions of Global Biomes
Land, 2023 Soil organic carbon (SOC) is heterogeneous, consisting of fractions with differing turnover rates. Climate, vegetation, and soil properties can all affect the characteristics of these different soil carbon fractions.

A radiocarbon database for Scottish archaeological samples [PDF]
, 2000 For the majority of dating laboratories and their respective user communities, the journal Radiocarbon is no longer regarded as the medium for primary publication of radiocarbon measurements.

The Mississippian fin de siècle in the middle Cumberland region of Tennessee [PDF]
, 2018 Bayesian chronological modeling is used to investigate the chronology for a large-scale human depopulation event during the Mississippian period (AD 1000–1600) known as the Vacant Quarter phenomenon.

DENDROCHRONOLOGY AND RADIOCARBON DATING [PDF]
Radiocarbon, 2021 ABSTRACTBoth dendrochronology and radiocarbon (14C) dating have their roots back in the early to mid-1900s. Although they were independently developed, they began to intertwine in the 1950s when the founder of dendrochronology, A. E. Douglass, provided dated wood samples for Willard Libby to test his emerging 14C methods.

Social and biophysical vulnerability of prehistoric societies to Rapid Climate Change
Documenta Praehistorica, 2010 Previous studies of the impact of Rapid Climate Change (RCC) on prehistoric com- munities have often been restricted in their explanatory power due to the lack of an appropriate analytical tool capable of combining palaeoclimate data with archaeological ...

Concepts of probability in radiocarbon analysis
Documenta Praehistorica, 2011 In this paper we explore the meaning of the word probability, not in general terms, but restricted to the field of radiocarbon dating, where it has the meaning of ‘dating probability assigned to calibrated 14C-ages’.
