Tracing giants through time
Introduction Sperm whales (Physeter macrocephalus) are deep-diving apex predators whose offshore ecology limits direct observation. Stable isotope analysis is widely used to infer cetacean diet and habitat use, but its application to archaeological whale remains remains rare despite the regular occurrence of sperm whales in zooarchaeological assemblages. Here, we combine stable carbon (δ13C) and nitrogen (δ 15 N) isotope analysis with zooarchaeol…
Sedimentary ancient DNA metagenomic analysis provides new insights into farming in central Norway from the Bronze Age to late Medieval period
Sedimentary ancient DNA (sedaDNA) has been proposed as a key methodology for reconstructing paleoclimates and biodiversity over time. To a lesser extent, it has been explored as a complementary tool for reconstructing human-driven local environmental changes over time, such as those explored in open air archaeological sites. Our study employs a sedaDNA metagenomic approach to investigate land use and environmental change at the archaeological sit…
Determining vertical growth patterns and tissue of maximum age using radiocarbon dating in the long-lived Namib Desert plant Welwitschia mirabilis
Welwitschia mirabilis , a unique gymnosperm native to Namibia and Angola, is a keystone plant species in the Namib Desert. It represents the only extremely long-lived non-clonal plant species occurring under hyperarid desert conditions, yet limited attempts have been made to accurately determine its age. Here, we present radiocarbon dates from a dead, sectioned Welwitschia of moderate size. We find the outer caudex tissue growth to progressively …
Marine reservoir effects in early Christian graves from Norway
We investigated radiocarbon dates of human bone samples from several medieval sites in Trondheim, central Norway. Stable isotope data was used to estimate marine correction for the radiocarbon dates, which is necessary to correct the radiocarbon ages and establish age models for the archaeological layers. We observed that a marine correction without ΔR does not lead to a well-defined model for all sites. Allowing a variable ΔR improves the model,…
Modeling the contribution of carbon sources using cellulose 14C concentrations in subannual tree ring increments over the 1963 bomb spike
Measurements of the radiocarbon ( 14 C) content of subannual wood cellulose samples over the 1963 bomb spike have revealed an apparent delay between the increase in atmospheric radiocarbon content and that of wood cellulose. This delay is apparent in both coniferous and deciduous tree species and is of a magnitude of approximately 4 weeks. The delay in wood cellulose 14 C change as measured in a Sitka spruce from Washington state, USA, was previo…
Unravelling the History of a Venetian Antiphonary
We present the results of a multifaceted study of an antiphonary—liturgical song book—presumably made in Venice in 1607, now in the Ringve, National Music Museum of Norway in Trondheim 1 . The book is hand-sewn on raised cords, bound in full leather on cardboard covers, originally with metal clamps. The paper block consists of pages printed in black and red that include both song texts and music scores. The red ink is based on vermillion and red …
The Radiocarbon Sample Archive of Trondheim
Atmospheric CO 2 samples have been collected by the Trondheim Radiocarbon Laboratory since the 1960s. The remaining material from the measurements has been precipitated as CaCO 3 and stored in glass containers. We investigated some of the stored samples to assess whether the material could still be used for remeasurements of atmospheric radiocarbon ( 14 C) content, or if it has been contaminated during the years of storage. We attempted different…
Study of Bio-Based Carbon Fractions in Tires and Their Pyrolysis Products
Wasted tires are the great source of fuel and valuable components but could be a cause of environmental and land pollution. This study shows the detailed method for the determination of radiocarbon isotope ( 14 C) concentration in tires and their pyrolysis products. Samples are taken from truck and passenger car tires in the form of shredded rubber, pyrolysis oil and recovered carbon black. Liquid scintillation counting (LSC) and accelerator mass…
Gas Ion Source Performance of the Environmicadas at Hekal Laboratory, Debrecen, Hungary
A coupled accelerator mass spectrometer–gas interface system has been successfully operating at the Hertelendi Laboratory of Environmental Studies, Debrecen, Hungary, since 2013. Over the last 6 years more than 500 gas targets were measured below 100 μg carbon content for carbon isotopic composition. The system was tested with blanks, OxII, IAEA-C1, IAEA-C2, and IAEA-C7 standards. The performance of our instrumentation shows good agreement with o…
Findings from an in-Depth Annual Tree-Ring Radiocarbon Intercomparison
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 …
Status report of the Trondheim Radiocarbon Laboratory
The Trondheim radiocarbon ( 14 C) laboratory has evolved from a traditional radiocarbon decay counting laboratory to an accelerator mass spectrometry (AMS) facility primarily measuring 14 C. This evolution required adjustments in sample preparation and data handling to match the capacity of the AMS system and reduction in sample sizes to about 1 mgC. We summarize here the steps involved in dating a sample at the National Laboratory for Age Determ…
The 1953–1965 rise in Atmospheric bomb 14 C in Central Norway
Sub-annual measurements, eight increments per year, of cellulose in a Scots pine tree growing in central Norway are presented as a proxy for tropospheric 14 CO 2 at biweekly to monthly resolution. The results are validated by comparison to direct atmospheric measurements in the years 1959–1965, and a new dataset is obtained for 1953–1958. In this period, our cellulose measurements deviate from the Bomb 13 NH1 calibration curve, which is derived f…
Radiocarbon Calibration around AD 1900 from Scots Pine ( Pinus Sylvestris ) tree rings from Northern Norway
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 P…
