Freshwater reservoir effect for mollusks in the lower and central Murray River, Australia
Since the 1950s, archaeological research conducted along the middle reaches of the Murray River has relied on radiocarbon dating of freshwater mollusk shell to establish the chronology of human occupation within this region as well as support larger models of human occupation timing within Australia. Despite this, there has been no investigation into the potential freshwater reservoir effect (FRE) for the middle reaches of the Murray River. In th…
An automated processing line for the extraction of dissolved inorganic carbon from water for radiocarbon analysis
At ANSTO, we have developed an automated dissolved inorganic carbon (DIC) processing line, known as A-DIC, designed to sequentially process 10 water samples for radiocarbon analysis without any operator intervention. The A-DIC works at ambient pressure using helium (He) gas as a carrier. It includes a water pump capable of drawing adjustable sample volumes between 22-180 mL into a 250 mL reaction vessel. Upon the addition of 5 mL of phosphoric ac…
Radiocarbon Dating Informs Tree Fern Population Dynamics and Disturbance History of Temperate Forests in Southeast Australia
Tree ferns are slow-growing and long-lived components of temperate forests; however, these characteristics make determining size-age and population dynamics through mensuration approaches problematic while dendroecological approaches cannot be used. In this study, we use radiocarbon ( 14 C) dating of Cyathea australis and Dicksonia antarctica to (1) determine their age-to-size relationships, (2) reconstruct the age distribution of tree fern speci…

How old is X-ray art? Minimum age determinations for early X-ray rock art from the ‘Red Lily’ (Wulk) Lagoon rock art precinct, western Arnhem Land
Building the Radiocarbon Chronology for the Archaeological Site Ufa-II: Is this the Elusive “Bashkort” of Medieval Sources
A suite of accelerator mass spectrometry (AMS) radiocarbon dates for the Ufa-II archaeological site in Bashkortostan, Russia, is obtained for the first time. Dating was done on charcoal samples from a sequence of cultural deposits collected during the 2011 digging season. An age-depth chronology is established using the Bayesian deposition General Outlier P_Sequence model. The oldest age for the site at the horizon immediately over the sterile gr…
Using the 14 C Bomb Pulse to Date Young Speleothems
Three modern speleothems were sampled at high resolution for radiocarbon analysis to identify their bomb-pulse signatures and to construct chronologies. Each speleothem exhibited a different 14 C response, presumed to be related to site characteristics such as vegetation, temperature, rainfall, depth below the surface, and water pathway through the aquifer. Peak 14 C activity for WM4 is 134.1 pMC, the highest cited thus far in the literature and …
New 14 C Ages on Cellulose from Diprotodon Gut Contents: Explorations in Oxidation Chemistry and Combustion
We report radiocarbon ages on cellulose isolated from the gut contents of a Diprotodon found at Lake Callabonna, South Australia. The maximum age obtained corresponds to a minimum age of >53,400 BP for this extinct giant marsupial. This is older than, and hence consistent with, the generally accepted Australian megafauna extinction window. We argue that dichromate and other strong oxidants are less selective than chlorite for lignin destruction i…
The Antares AMS Centre: A Status Report
The ANTARES accelerator mass spectrometry facility at Lucas Heights Research Laboratory is operational and AMS measurements of 14 C, 26 Al and 36 Cl are being carried out routinely. Measurement of 129 I recently commenced and capabilities for other long-lived radioisotopes such as 10 Be are being established. The overall aim of the facility is to develop advanced programs in Quaternary science, global climate change, biomedicine and nuclear safeg…
