  • Δ 14 C Peaks Appearing in Earlywood and Latewood Tree Rings (Ad 770–780) in Northeastern Arizona

    Open AccessJunghun Park, J Southon et al.ARTICLERadiocarbon2021References: 19

    The AD 775 peak in Δ 14 C (henceforth, M12) was first measured by Miyake et al. and has since been confirmed globally. Here we present earlywood and latewood Δ 14 C values from tree rings of pinyon pine ( Pinus edulis ) from Mummy Cave, Canyon de Chelly National Monument, Chinle, Arizona, USA, for the period AD 770–780. These data reconfirm the timing of M12 and show a small rise in Δ 14 C in AD 774 latewood. Allowing for the delay in lateral tra…

  • Findings from an in-Depth Annual Tree-Ring Radiocarbon Intercomparison

    Open AccessLukas Wacker, Marian Scott et al.ARTICLERadiocarbon2020Cited by: 11References: 14

    The radiocarbon ( 14 C) calibration curve so far contains annually resolved data only for a short period of time. With accelerator mass spectrometry (AMS) matching the precision of decay counting, it is now possible to efficiently produce large datasets of annual resolution for calibration purposes using small amounts of wood. The radiocarbon intercomparison on single-year tree-ring samples presented here is the first to investigate specifically …

  • Changes of Subtropical North Pacific Radiocarbon and Correlation with Climate Variability

    Open AccessEllen R M Druffel, S Griffin et al.ARTICLERadiocarbon2001Cited by: 7References: 38

    We show that high-precision radiocarbon (Δ 14 C) measurements from annual bands of a Hawaiian surface coral decreased by 7‰ from AD 1893 to 1952. This decrease is coincident with the Suess Effect, which is mostly due to the dilution of natural levels of 14 C by 14 C-free fossil fuel CO 2 . This decrease is equal to that expected in surface waters of the subtropical gyres, and indicates that the surface waters of the North Pacific were in steady s…

    RADIOCARBON is an international journal published three times a year in the United States. Besides our regular issues, which consist mainly of articles of original research, reports of techniques, and date lists, we also publish proceedings of international conferences on radiocarbon dating and related fields. These may appear in Special Issues (see below) or in volumes outside the regular journal series. We ask contributors to use simple, straig…
