Anomalous radiocarbon ages for foraminifera shells [PDF]
Paleoceanography, 2006 The causes for discordant radiocarbon results on multiple species of planktonic foraminifera from high‐sedimentation‐rate marine sediments are investigated. We have documented two causes for these anomalous results. One is the addition of secondary radiocarbon for which we have, to date, only one firm example. It involves an opal‐rich sediment.

New hydroxyproline radiocarbon dates from Sungir, Russia, confirm early Mid Upper Palaeolithic burials in Eurasia. [PDF]
PLoS ONE, 2014 Sungir (Russia) is a key Mid-Upper Palaeolithic site in Eurasia, containing several spectacular burials that disclose early evidence for complex burial rites in the form of a range of grave goods deposited along with the dead.

A deep-sea coral record of North Atlantic radiocarbon through the Younger Dryas: Evidence for intermediate water/deepwater reorganization [PDF]
, 2006 Our record of Younger Dryas intermediate-depth seawater Δ^(14)C from North Atlantic deep-sea corals supports a link between abrupt climate change and intermediate ocean variability.

Estimating marine reservoir effects in archaeological chronologies: Comparing ΔR calculations in Prince Rupert Harbour, British Columbia, Canada [PDF]
, 2018 The best method for quantifying the marine reservoir effect (MRE) using the global IntCal Marine13 calibration curve remains unresolved. Archaeologists frequently quantify uncertainty on MRE values as errors computed from single pairs of ...

Calibration of Radiocarbon Ages by Computer [PDF]
Radiocarbon, 1989 A PC-based computer program for automatic calibration of 14C dates has been developed in Turbo-Pascal (version 4.0). It transforms the Gaussian 14C dating result on the 3σ level into a real calendar age distribution. It uses as a calibration curve a spline function, generated along the calibration data points as published in the Radiocarbon Calibration

Isotope (14C and 13C) analysis of deep peat CO2 using a passive sampling technique [PDF]
, 2009 We developed and tested a new method to collect CO<sub>2</sub> from the surface to deep layers of a peatland for radiocarbon analysis. The method comprises two components: i) a probe equipped with a hydrophobic filter that allows entry of ...

Influence of mollusk species on marine DELTA R determinations [PDF]
, 2005 Radiocarbon ages were measured on replicate samples of burnt grain and 5 mollusk species collected from a single sealed layer at an archaeological site (Hornish Point) on the west coast of South Uist, Scotland.

New Zealand radiocarbon age measurements—5 [PDF]
New Zealand Journal of Geology and Geophysics, 1962 A tabulated list of 117 samples dated by the radiocarbon method is given. Proportional counting of carbon dioxide gas was the method used, and the ages were calculated in terms of a half life of 5568 plus or minus 30 yr. Samples from Antarctica and the deep ocean are excluded.
