Radiocarbon as a Dating Tool and Tracer in Paleoceanography
Reviews of Geophysics, 2022 Radiocarbon is an extremely useful carbon cycle tracer and radiometric dating tool. Here, we review the main principles and challenges involved in the use of radiocarbon in paleoceanography.

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.

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.

Riken Natural Radiocarbon Measurements IX [PDF]
Radiocarbon, 1977 The C14 dates given below are continued from our previous list (R., 1970, v. 12, p. 559–576), and results obtained mainly during 1970 are described. A 2.7 L stainless steel counter and a 3.3 L copper counter are used, yielding background counting rates of 5.5 and 8.5 cpm, respectively, when filled with dead CO2 at ca. 1.8 atm.

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 ...

Should archaeologists care about 14C inter-comparisons? Why? A summary report on SIRI [PDF]
, 2017 Radiocarbon (14C) dating is used widely in many projects as a basis for the creation and testing of chronological constructs. 14C measurements are by their nature complex and the degree of sample pretreatment varies considerably depending on the material.

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’.

INFERENCE FROM LARGE SETS OF RADIOCARBON DATES: SOFTWARE AND METHODS
Radiocarbon: An International Journal of Cosmogenic Isotope Research, 2020 The last decade has seen the development of a range of new statistical and computational techniques for analysing large collections of radiocarbon (14C) dates, often but not exclusively to make inferences about human population change in the past.

Longevity Estimates of Canary Palms and Dragon Trees via Radiocarbon Dating: Initial Results
Plants, 2023 Correctly estimating the maximum lifespan of plant species is a necessary component of demographic and life-history studies, which, in turn, are needed for understanding climatic impacts.
