INTCAL98 Radiocarbon Age Calibration, 24,000–0 cal BP [PDF]
Radiocarbon, 1998 The focus of this paper is the conversion of radiocarbon ages to calibrated (cal) ages for the interval 24,000–0 cal BP (Before Present, 0 cal BP = AD 1950), based upon a sample set of dendrochronologically dated tree rings, uranium-thorium dated corals, and varve-counted marine sediment.

Iron Age to Medieval entomogamous vegetation and Rhinolophus hipposideros roost in south-eastern Wales (UK) [PDF]
, 2006 Karst cave systems are well developed in Wales (UK) and, in some instances, constitute important bat roosts. Ogof Draenen, near Blaenavon in south-east Wales, is the most recent major cave discovery (1994) with already > 70 km of passages explored ...

The North Atlantic marine reservoir effect in the early Holocene: implications for defining and understanding MRE values [PDF]
, 2007 The marine reservoir effect (MRE) is a <sup>14</sup>C age offset between the oceanic and atmospheric carbon reservoirs. The MRE is neither spatially nor temporally constant and values may deviate significantly from the global model average ...

Radiocarbon in dissolved organic carbon of the Atlantic Ocean
Geophysical Research Letters, 2016 Marine dissolved organic carbon (DOC) is produced in the surface ocean though its radiocarbon (14C) age in the deep ocean is thousands of years old. Here we show that ≥10% of the DOC in the deep North Atlantic is of postbomb origin and that the 14C age ...

Geochronological implications of 210Pb and 137Cs mobility in cave guano deposits
International Journal of Speleology, 2021 Some recent publications on the paleo- and historical environmental interpretation of bat guano sequences have relied on 210Pb and 137Cs distribution to establish age-depth models, even when these are at odds with radiocarbon models in the lower parts of

Radiocarbon age differences between coexisting foraminiferal species [PDF]
Paleoceanography, 1999 Radiocarbon‐age measurements on single species of foraminifera from a core on the Ceara Rise demonstrate the importance of the joint effect of bioturbation and variable rain abundance of foraminifera. The relatively high mixed layer ages for Pulleniatina obliquiloculata reflect, at least in part, an early Holocene peak in its abundance while the ...

Errors in the radiocarbon dating of deposits in Finland from the time of deglaciation [PDF]
Bulletin of the Geological Society of Finland, 1974 Some radiocarbon dates of sediments from the area of the Salpausselkä moraines, and north of them in the area deglaciated after c. 10200 B.P., are too old and at variance with a number of radiocarbon dates for the regional pollen assemblage zones ...

14C dating of the lime burial of Cova de Na Dent (Mallorca, Spain): optimization of the sample preparation and limitations of the method [PDF]
, 2015 Lime burials are a characteristic phenomenon of the protohistoric funerary tradition on the Balearic Islands. At Cova de Na Dent, six samples, representing the entire stratigraphy of the lime burial, were taken for analysis.
