Lake Tyrrell is a large salt lake in outback Australia . We aim to make the lake one of the most completely understood hypersaline ecosystems in the world. To achieve this, we are combining environmental genomics where the genome of all predominant microorganism in the lake water are sequenced (>1 billion base...

The Southern Ocean is a key contributor to global climate. It regulates the absorption of CO2 into the ocean, plays a key role in ocean heat uptake and most likely influenced abrupt climate variability in the past. However, the processes that limit Southern Ocean circulation occur at very fine scales,...

The ocean-atmosphere interface is a highly complex and extremely important part of the climate system. The dynamics and thermodynamics of the sea surface govern fluxes of heat, momentum and CO2 between the atmosphere...

The Earth’s inner core is a planet within a planet: a hot sphere with a mass of one hundred quintillion tons of iron and nickel that lies about 5150 kilometres beneath our feet, still waiting to be discovered. Modern global seismology serves as an inverted telescope with which we can probe the Earth's deepest shell.

Understanding present-day melting patterns of polar ice caps and the contribution to present-day sea level variations requires first unravelling the puzzle of how the continents are still adjusting after the melting that has occurred since the Last Glacial Maximum around 10,000 years ago. This is a complicated...

New analytical techniques, developed to analyse the platinum group elements (PGEs) at the ultra low levels in which they are found in granitic rocks, allow us to make the first reliable analyses of the PGEs in these rocks. The aim of this fundamental research is to identify the timing of, and understand the causes...

A Tectonic Reconstruction Project by Tomas O'Kane, PhD Candidate
We have been developing rigid plate animations illustrating the formation of porphyry Cu-Au and gold deposit formation throughout the last 25 Ma. The oceanic Nazca Plate is currently subducting under the South American continental lithosphere...

Classical petrological and geochemical tools provide only limited insights into extreme metamorphism because fast diffusion of major elements and annealing effectively eliminate crucial information.We are developing new and innovative tools for high-resolution investigation of partial melting and high-grade...

The Virtual Earth describes the real or material Earth - it is an electronic rendition of our planet as it is today. The aspect upon which we have specifically focussed is the geometric description of the planetary lithosphere, in particular the 3D geometry of the major subducting slabs. These geometries have been...

Many tsunami source inversion techniques have already been developed to derive source models with the assumption that tsunami generation is due to slip on a single large fault. Therefore, these inversion techniques cannot determine to what extent subsidiary phenomena - such as submarine landslides, block movement,...

The recycling of elements through convergent plate boundaries strongly influences the chemical differentiation of Earth. It is widely accepted that hydrous fluid sourced from dehydrating subducting crust promotes melting in the mantle wedge and the formation of arc magmas. We investigate the liberation of volatiles...

Some of the most fundamental observations used to understand the physics of earthquakes are estimates of the spatio-temporal evolution of earthquake rupture on a fault surfaceusing seismic, tsunami and geodetic data. To date, uncertainties of rupture parameters are poorly understood, and the effect of choices such...

Eastern Indonesia is one of the least well-understood geological domains on Earth, yet the region provides a remarkable location for unraveling some of the major puzzles of plate tectonics. 30 broadband seismometers were deployed across the transition from subduction to collision from 2014-2018 to image the deep Earth.
