The 2018 National Seismic Hazard Assessment for Australia »

2pm 9 August 2018

Since the publication of the Global Seismic Hazard Assessment Project (GSHAP) hazard map in 1999, Australia has stood out as a region of high earthquake hazard among its stable continental region (SCR) peers. But does this assessment reflect our current understanding of earthquake processes and seismic hazard in...

Seismic velocity and anisotropy of the inner core »

5pm 7 August 2018

Since the discovery of the inner core via observational seismology in 1936, the nature of its internal structure and dynamics has been at the forefront of deep Earth research. Increasingly complex models are being developed to accommodate both small and large scale features observed in multiple seismic datasets....

Exploring barnacle exoskeleton formation »

2pm 2 August 2018

Barnacles are ancient arthropods that, as adults, consist of a soft organism surrounded by a hard, often calcitic, outer shell that the organism produces for protection. While research has been done into the glue-like cement that...

Inference of the lithosphere of Northeast China from passive seismic receiver based methods »

5pm 31 July 2018

The NE China plain (NECP) consists of complex lithospheric domains characterised by the co-existence of complex geodynamic processes such as crustal thinning, active intraplate Cenozoic volcanism and low velocity anomalies. The focus of this study is to constrain the complex lithospheric structure beneath Northeast...

A journey from water in olivine to your cellphone screen »

1.30pm 27 July 2018

In this talk, we will discuss how a global vision of molecular processes in silicates is important to understand how nanoscale processes influence megascale geological phenomenons and human material making. I will show how "big picture" questions in geosciences actually are intimately related to fundamental...

Modelling the dynamics of past climate change »

2pm 26 July 2018

I will discuss the dynamics of three different climate events in the past: the Paleocene-Eocene Thermal Maximum (PETM, ∼55 million years 
before present) and Heinrich Events 1 and 4 (17.5-15.5ka BP and 40.2-38.8ka BP). The PETM was a period of rapid warming marked by a negative carbon isotope excursion and...

Global sea-level during the mid- to Late Pliocene (~3.3-2.6 Ma) and implications for polar ice sheet variability »

2pm 19 July 2018

The mid-Pliocene (3.3 -3 Ma) has long been considered an analogue for future global warming with atmospheric CO2 concentration of 400 ppm, average surface temperatures 2-3 °C higher than pre-industrial and a lack of large continental ice sheets in the Northern Hemisphere. This period of equable climate...

Oxygen isotope systematics of ordinary chondrite chondrules: insights into the inner solar system planetary reservoir »

5pm 17 July 2018

Triple oxygen isotope measurements (16O, 17O, and 18O) revolutionized our understanding of meteoritics and cosmochemistry since the discovery of large and ubiquitous oxygen isotopic anomalies in refractory inclusions within carbonaceous chondrite meteorites in the early 70s. Since...
