Radiocarbon Calibration around AD 1900 from Scots Pine ( Pinus Sylvestris) tree rings from Northern Norway

ABSTRACT To resolve an inconsistency around AD 1895 between radiocarbon ( 14 C) measurements on oak from the British Isles and Douglas fir and Sitka spruce from the Pacific Northwest, USA, we measured the 14 C content in single-year tree rings from a Scots pine tree ( Pinus sylvestris L.), which gre...

Description
Summary:ABSTRACT To resolve an inconsistency around AD 1895 between radiocarbon ( 14 C) measurements on oak from the British Isles and Douglas fir and Sitka spruce from the Pacific Northwest, USA, we measured the 14 C content in single-year tree rings from a Scots pine tree ( Pinus sylvestris L.), which grew in a remote location in Saltdal, northern Norway. The dataset covers the period AD 1864–1937 and its results are in agreement with measurements from the US Pacific coast around 1895. The most likely explanation for older ages in British oak in this period seems to be 14 C depletion associated with the combustion of fossil fuels.
