Comparability of Radiocarbon Measurements in Dissolved Inorganic Carbon of Seawater Produced at Eth-Zurich
Radiocarbon observations (Δ 14 C) in dissolved inorganic carbon (DIC) of seawater provide useful information about ocean carbon cycling and ocean circulation. To deliver high-quality observations, the Laboratory of Ion Beam Physics (LIP) at ETH-Zurich developed a new simplified method allowing the rapid analysis of radiocarbon in DIC of small seawater samples, which is continually assessed by following internal quality controls. However, a compar…
Radiocarbon Protocols and First Intercomparison Results From the Chronos 14 Carbon-Cycle Facility, University of New South Wales, Sydney, Australia
The Chronos 14 Carbon-Cycle Facility is a new radiocarbon laboratory at the University of New South Wales, Australia. Built around an Ionplus 200 kV MIni-CArbon DAting System (MICADAS) Accelerator Mass Spectrometer (AMS) installed in October 2019, the facility was established to address major challenges in the Earth, Environmental and Archaeological sciences. Here we report an overview of the Chronos facility, the pretreatment methods currently e…
Annual Variation in Atmospheric 14 C Between 1700 BC and 1480 BC
In 2018 Pearson et al. published a new sequence of annual radiocarbon ( 14 C) data derived from oak ( Quercus sp.) trees from Northern Ireland and bristlecone pine ( Pinus longaeva ) from North America across the period 1700–1500 BC. The study indicated that the more highly resolved shape of an annually based calibration dataset could improve the accuracy of 14 C calibration during this period. This finding had implications for the controversial …
High Precision 14 C Analysis in Small Seawater Samples
A new method to extract CO 2 in seawater samples for the determination of F 14 C has been developed in the Laboratory of Ion Beam Physics at ETH Zurich. The setup consists of an automated sampler designed to extract dissolved inorganic carbon (DIC) from 7 samples in a row, by flushing the seawater with He gas to extract CO 2 . The fully automated method is controlled via a LabVIEW program that runs through all consecutive steps: catalyst precondi…
