Radiocarbon dates on Kauri wood from the Late Glacial (Hogg et al 2016) and around Heinrich Event 3 (Turney et al 2016). The radiocarbon dates are on dendrochronological sequences of rings with known age separation and useful for calibration of other radiocarbon dates and looking at geophysical processes.

The data comprises of dimensions of large wood pieces and the isotope composition (radiocarbon, stable carbon isotopes) of cellulose extracted from the wood samples. Large Wood (LW) samples were collected from the Mackenzie River delta region, Northwest Territories, Canada, in August 2019 and were analysed at the National Environmental Isotope Facility, UK. The scientific aims were to help constrain the source and age of wood carried by this large river system draining to the Arctic Ocean.
