Abstract A high‐resolution, multiproxy record encompassing the last glacial–interglacial transition is presented for Native Companion Lagoon, a coastal site in subtropical eastern Australia. Rates of aeolian sedimentation lake were established by trace element analyses lacustrine sediments and used as proxy aridity. In conjunction with sediment moisture content, charcoal pollen these provide multi‐decadal palaeoenvironmental variability period 33–18 k cal. yr BP. Results indicate that Last...
Abstract The timing and duration of the coldest period in last glacial stage, often referred to as maximum (LGM), has been observed vary spatially temporally. In Australia, this is characterised by colder, some places more arid, climates than today. We applied Monte-Carlo change point analysis all available continuous proxy records covering period, primarily pollen records, from across Australia (n = 37) assess change. find a significant occurred (within uncertainty) at 28.6 ± 2.8 ka 25...
A revised Holocene sea-level history for the southern Gulf of Carpentaria is presented based on new data from South Wellesley Archipelago and age recalibration previous research. Results confirm that rising sea levels during most recent post-glacial marine transgression breached Arafura Sill ca. 11,700 cal. yr BP. Sea continued to rise –30 m by 10,000 BP, leading full conditions. By 7700 reached present mean (PMSL) an elevation between 1.5 2 above PMSL. level remained + 7000 4000 followed...
ABSTRACT Few Australian wetlands have persisted since the Last Glacial Maximum, with fewer still in existence through entire last glacial cycle. The absence of wetlands, which itself indicates periods moisture deficit, means there are few continuous climate and environmental change records covering this critical period. lack wetland persistence also raises question how plant animal species that require permanent survived Sixteen been cored dated on North Stradbroke Island (Minjerribah) – a...
The Great Sandy Region (incorporating Fraser Island and the Cooloola sand-mass), south-east Queensland, contains a significant area of Ramsar-listed coastal wetlands, including globally important patterned fen complexes. These mires form an elaborate network pools surrounded by vegetated peat ridges are only known subtropical, Southern Hemisphere examples, with wetlands this type typically located in high northern latitudes. Sedimentological, palynological charcoal analysis from Wathumba...
The unique combination of landscapes and processes that are present operate on Fraser Island (K'gari) create a dynamic setting is capable recording past environmental events, climate variations former landscapes. Likewise, its geographic position makes sensitive to those events processes. Based optically stimulated luminescence dating, the records archived within world's largest sand island span period has potential exceed 750 ka contain specific extremely high resolution over 40,000 years....
A palaeoecological record has been constructed for Myora Springs, North Stradbroke Island that provides a detailed picture of environmental change this site over the last millennium.From ~800 to 500 years ago is dominated by paperbark (Melaleuca) swamp surrounded open eucalypt woodland and only small amount rainforest.This period may reflect drier conditions persistent 'warm' El Nifio Southern Oscillation event possibly associated with Little Ice Age phenomenon.From ~500 200 vegetation...
Composite indices have been widely used to rank the environmental performance of nations. Such can be useful in communicating complex information as a single value and potential generate political media awareness issues. However, poorly constructed, or communicated indices, hinder efforts identify failings, there are considerable differences among existing indices. Here, we provide review conceptual frameworks methodological choices for enhance our understanding their accuracy applicability....
Abstract Episodic deposition of light absorbing impurities on glaciers reduces albedo and exacerbates snow melt. In 2019/2020 a devastating Australian bushfire desert dust event combined with favorable meteorological conditions transported an unprecedented mass across the Tasman Sea turning Southern Alps Aotearoa New Zealand red. Here we use time lapse cameras, airmass back trajectories, impurity geochemistry, remote sensing to quantify timing, provenance, event. Deposited in late November...
ABSTRACT The iconic sand dune systems of Minjerribah (North Stradbroke Island), in southeastern Queensland, Australia, host numerous lakes and swamps containing organic‐rich sediment deposits that record changes climate, fire surrounding vegetation. Palaeoenvironmental reconstructions from individual locations can provide insights into the environment, but determining regional extent these is seldom possible a single site. Multi‐site compilations help elucidate geographical nature...
