ABSTRACT 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, facility was established to address major challenges Earth, Environmental and Archaeological sciences. Here we report overview facility, pretreatment methods currently employed (bones, carbonates, peat, pollen, charcoal, wood) results...
ABSTRACT This paper reconstructs past flooding from a range of settings in Lockyer Creek, key tributary the mid‐Brisbane River, which experienced extreme flood events AD 2011 and 2013. Optically stimulated luminescence samples ( n = 110) were collected alluvial material preserved within‐channel benches floodplains. Age distributions bedrock reaches confirm an event ∼ 300 years ago stripped valley alluvium to bedrock. In unconfined floodplain deposits indicate lateral stability over 6000...
Monosomy of the human chromosome 6p terminal region results in a variety congenital malformations that include brain, craniofacial, and organogenesis abnormalities. To examine genetic basis these phenotypes, we have carried out an unbiased functional analysis syntenic mouse genome (proximal Mmu13). A screen for recessive mutations this recovered thirteen lines with phenotypes relevant to clinical conditions. These two loci cause holoprosencephaly, underlie anophthalmia, one which also...
Macroscopic charcoal records from wetland sediment cores are used to reconstruct long-term of fire frequency. A central premise for the use this tool is that macroscopic (>125 μm) represents local fires involving vegetation. Several reveal there may often be exceptions these guidelines. Previous studies have shown particles larger than 1 cm long can travel at least 20 km location a fire. We present observations unprecedented long-distance transport large (⩽5 long) 50 west Sydney,...
Abstract In Australia, multidecadal periods of floods and droughts have major economic consequences. Due to the short duration Australian instrumental precipitation records, it is difficult determine patterns these periods. Proxy records can be used create long‐term rainfall reconstructions for regions that are lacking data. However, spatial extent over which single‐site proxy applied poorly understood. Southeast Queensland (SEQ) an area where tree rings reconstruct patterns, but their...
ABSTRACT Tree-ring series offer considerable potential for the development of environment-sensitive proxy records. However, with traditional increment cores, only small amounts wood are often available from annual tree-ring sequences. For this reason, it is important to understand reliability (and reproducibility) radiocarbon measurements obtained small-sized samples. Here we report F 14 C results Chronos Carbon-Cycle Facility modern tropical Australian tree samples over a range four...
Abstract We report the discovery of an ancient forest bed near Stanley, on Falkland Islands, second such deposit identified South Atlantic island archipelago that is today marked by absence native tree species. Fossil pollen, spores and wood fragments preserved in this buried at Tussac House show source vegetation was characterized a floristically diverse rainforest dominated Nothofagus -Podocarpaceae communities, similar to cool temperate forests/woodlands Magellanic evergreen rainforests....
Context Populations of the threatened plant Acacia dangarensis at Mount Dangar (Hunter Valley, New South Wales) may best be managed by recognising centurial, rather than decadal, change in habitat. Aim Multiple data sources have been used to explore hypothesis that above-ground presence A. is driven centurial-scale cycles climate (wet–dry phases) and fire. Methods Current-day floristic composition contrasted with documented pre- post-1900 botanical explorers for fire-sensitive Callitris...
In this study, we present a comprehensive atmospheric 14C record spanning from 1940 to 2016, derived 77 single tree rings of Cedrela odorata located in the Eastern Amazon Basin (EAB). This record, comprising 175 high-precision radiocarbon measurements obtained through accelerator mass spectrometry (AMS), offers detailed chronology post-1950 A.D. fluctuations Tropical Low-Pressure Belt (TLPB). To ensure accuracy and reliability, included 14C-AMS results successive cuts 1962 1963 conducted...
<p>In Australia the majority of tropical and subtropical regions lack any long-term (multi-decadal to centennial scale) instrumental climate records highlighting a need for alternatives such as proxy reconstructions. Despite this need, only limited number terrestrial sources are available. Tree-rings provide one few options reconstructions yet very little dendrochronological investigation has been undertaken early assessments Australian species in 1970s 1980s indicated most had...
