A robust understanding of Antarctic Ice Sheet deglacial history since the Last Glacial Maximum is important in order to constrain ice sheet and glacial-isostatic adjustment models, explore forcing mechanisms responsible for retreat. Such can be derived from a broad range geological glaciological datasets recent decades have seen an upsurge such data gathering around continent Sub-Antarctic islands. Here, we report new synthesis those datasets, based on accompanying series reviews data,...
The East Antarctic Ice Sheet (EAIS) is the largest continental ice mass on Earth, and documenting its evolution since Last Glacial Maximum (LGM) important for understanding present-day future behaviour. As part of a community effort, we review geological evidence from Antarctica that constrains sheet history throughout this period (∼30,000 years ago to present). This includes terrestrial cosmogenic nuclide dates previously glaciated regions, 14C chronologies glacial post-glacial deposits...
We launched the VegeSafe program in 2013 to assist Australians concerned about exposure contaminants their soils and gardens. analyses garden provided by citizens for trace metals at our laboratory little no cost, with easy-to-follow guidance on any intervention required. The response was overwhelming-Australians submitted 17,256 from 3,609 homes, turn researchers now have unparalleled household-scale data, providing new insights into urban metal contamination. results are sobering, 35% of...
Abstract The Protocol on Environmental Protection to the Antarctic Treaty requires that past and present work sites be cleaned up unless removal would result in greater adverse environmental impact than leaving contaminant its existing location. In early 1990s Australia began documentation of contaminated associated with research stations, which resulted an extensive record contamination at abandoned stations waste-disposal sites. Currently technical capability remediate these does not exist...
Lake sediments in the Larsemann Hills contain a great diversity of biological and physical markers from which past environments can be inferred. In order to determine timing environmental changes it is essential have accurate dating sediments. We used radiometric ( 210 Pb 137 Cs), radiocarbon (AMS 14 C) uranium series 238 U) methods date cores eleven lakes. These were sampled on coastal inland transects across two main peninsulas, Broknes Stornes, together with single sample Bolingen...

The flow of water beneath the Antarctic Ice Sheet has recently been shown to involve drainage from and exchange between subglacial lakes, with routing over distances >100km. As is known be important ice‐sheet dynamics, changes basal may yield an response. Here we show that directions hydrological flowpaths are highly sensitive surface topography at certain sites in Antarctica. Surface elevation changes, 5 15 m, found sufficient produce significant flowpaths, which affect potential routes...
This article demonstrates that distinct and coherent silver sources can be discriminated from surface compositional analyses. In the first large-scale study of Archaic (pre-479 BC) Athenian coins in museum collections around world, we analysed 788 by Energy Dispersive X-ray Fluorescence (XRF) spectrometry with a mathematical correction to provide reliable composition for key diagnostic elements. Principal Component Analysis reveals patterns including at least one copper-lead-gold (Cu, Pb,...

Abstract A rock cairn, with two matchbooks buried beneath, was found on the summit of highest hill Thomas Island, Bunger Hills, East Antarctica. The are most likely from United States World War II-era ration packs, which were distributed to various military and civilian expeditions mid-1940s into 1950s. Hills first visited by Navy ‘Operation Highjump’ in February 1947, when a seaplane landed marine inlet, rather than lake as reported previously. Island Windmill’ January 1948, survey point...
As meso-order predators, snow petrels (Pagodroma nivea) play a significant role in the Antarctic food web. Changes their abundance can be related to availability of prey and thus provide an indication ecosystem health. The foraging grounds lie within pack ice open waters Southern Ocean, while nesting sites are restricted ice-free areas on mainland surrounding islands. Modern observations birds allow conclusions drawn about breeding performance ecology relation environmental parameters, such...
Over the last decades, climate change led to only moderate changes of East Antarctic Ice Sheet (EAIS). In recent years, however, modelling approaches and field experiments have shown that also EAIS is increasingly affected by ice mass losses. order obtain information on temporal/spatial sheet at margins major glaciers in Antarctica, northern Bunger Hills were visited within frame EASI3 "RV Polarstern" expedition period between 19. 29.

Thomas Island (Bunger Hills, East Antarctica) is a 34 square kilometre, deglaciated area potentially impacted by the Antarctic ice sheet and Remenchus Glacier from east, Shackleton Ice Shelf north Edisto west. Its glacial geology reveals complex interplay between these masses, which operate with different spatial temporal dynamics. This poster maps erosional depositional features allows inference of history advance retreat, sets framework for quantitative dating its deglaciation history....
A team of five undergraduate students participated in an ongoing research project that is developing a wireless multitargeted vital sign monitor (VSM), and as their capstone design developed hardware automated the VSM deployment.
