Genealogies and oral histories as chronological networks
Human genealogies serve multiple functions beyond documenting one's pedigree. They operate as complex social frameworks that structure knowledge, delimit group membership, explain historical causation, are political tools, and provide chronological foundations for understanding past events and processes across diverse knowledge systems. Archaeologists, ethnologists, and historians have long related historical information from genealogies and asso…
Development of the Intcal Database
The IntCal family of radiocarbon ( 14 C) calibration curves is based on research spanning more than three decades. The IntCal group have collated the 14 C and calendar age data (mostly derived from primary publications with other types of data and meta-data) and, since 2010, made them available for other sorts of analysis through an open-access database. This has ensured transparency in terms of the data used in the construction of the ratified c…
Dendroarchaeology in New Zealand
Accurately establishing calendar dates for Māori wooden objects would place them in a secure temporal context and enable aspects of manufacturing and use to be explored within and between sites, and across time. Dendrochronology has the potential to produce accurate and precise calendar dates for wooden artefacts but in New Zealand application of this technique to Māori cultural material is limited as there is almost no overlap between wood speci…
Early human occupation of a maritime desert, Barrow Island, North-West Australia
Anomalous mid-twentieth century atmospheric circulation change over the South Atlantic compared to the last 6000 years
Determining the timing and impact of anthropogenic climate change in data-sparse regions is a considerable challenge. Arguably, nowhere is this more difficult than the Antarctic Peninsula and the subantarctic South Atlantic where observational records are relatively short but where high rates of warming have been experienced since records began. Here we interrogate recently developed monthly-resolved observational datasets from the Falkland Islan…
Geological subsidence and sinking islands
W.R. Dickinson, as part of his wide study of the geological history of the Pacific islands, has linked the unique case of the deeply submerged Lapita site of Mulifanua in western Upolu (Samoa) to the slow subsidence of Upolu island. Recent archaeological research on the neighbouring small island of Manono has yielded new and detailed data on this geological process. A series of new dates has allowed us to define the speed of the subsidence and de…
Is there any Evidence for Regional Atmospheric 14 C Offsets in the Southern Hemisphere
Center for Accelerator Mass Spectrometry (CAMS) Tasmanian Huon pine ( Lagarostrobos franklinii ) decadal measurements for the interval AD 745–855 suggest a mean interhemispheric radiocarbon offset (20 ± 5 yr), which is considerably lower than the previously reported mean interhemispheric offset for the last 2 millennia (44 ± 17 yr). However, comparable University of Waikato (Wk) New Zealand kauri ( Agathis australis ) measurements show significan…
The New Zealand Kauri ( Agathis Australis ) Research Project
Wc describe here the New Zealand kauri ( Agathis australis ) Younger Dryas (YD) research project, which aims to undertake Δ 14 C analysis of ∼140 decadal floating wood samples spanning the time interval ∼13.1–11.7 kyr cal BP. We report 14 C intercomparison measurements being undertaken by the carbon dating laboratories at University of Waikato (Wk), University of California at Irvine (UCI), and University of Oxford (OxA). The Wk, UCI, and OxA lab…
High-Precision Radiocarbon Measurements of Tree-Ring Dated Wood from New Zealand
The best means for correcting Southern Hemisphere (SH) radiocarbon measurements, which are significantly influenced by temporal variations in the interhemispheric offset, is by the construction of a SH-specific calibration curve from dendrochronologically dated wood. We present here decadal 14 C measurements on dendrochronologically secure New Zealand kauri ( Agathis australis ), covering the period 195 BC–AD 995, extending the range of calibrati…
Bayesian Evaluation of the Southern Hemisphere Radiocarbon Offset during the Holocene
While an interhemispheric offset in atmospheric radiocarbon levels from AD 1950–950 is now well established, its existence earlier in the Holocene is less clear, with some studies reporting globally uniform 14 C levels while others finding Southern Hemisphere samples older by a few decades. In this paper, we present a method for wiggle-matching Southern Hemisphere data sets against Northern Hemisphere curves, using the Bayesian calibration progra…
Investigating the Interhemispheric 14 C Offset in the 1st Millennium AD and Assessment of Laboratory Bias and Calibration Errors
Past measurements of the radiocarbon interhemispheric offset have been restricted to relatively young samples because of a lack of older dendrochronologically secure Southern Hemisphere tree-ring chronologies. The Southern Hemisphere calibration data set SHCal04 earlier than AD 950 utilizes a variable interhemispheric offset derived from measured 2nd millennium AD Southern Hemisphere/Northern Hemisphere sample pairs with the assumption of stable …
New Marine ΔR Values for the South Pacific Subtropical Gyre Region
This paper presents 31 new ΔR results of known-age, pre-AD 1950 shells from the South Pacific subtropical gyre region, spanning from the Tuamotu Archipelago in the east to New Caledonia in the west. This doubles the number of available ΔR values for the Oceania region. These values indicate that the regional offset (ΔR) from the modeled radiocarbon marine age has remained relatively constant over the last 100 yr prior to 1950. Variation from the …
