Over the past decade, the Antarctic and Greenland Ice Sheets have been loosing its mass at an alarming rate.  Antarctic ice-shelves are melting by turbulent transport of heat and salt to the ice face, predominantly under the influence of warmer Circumpolar Deep Water entering ice shelf cavities from the surrounding...

The melting of Antarctica’s marine-terminating ice sheets is controlled by heat delivered from the Southern Ocean to the Antarctic margins, and is the largest uncertainty in future sea level rise. This project will use a combination of ocean modelling, theory and observations to predict future Antarctic melt rate.

Turbulent mixing plays an important role in the oceanic circulation energy balance. Energy is input at large scales from tides and surface wind stresses, and provides the energy required to bring deep, dense water back towards the surface via mixing. Mixing can...

The ocean is a sea of internal gravity waves. Similar to the gravity waves that propagate over the ocean surface and break along our coastlines, internal waves propagate great distances through the ocean interior. These waves are generated at the ocean surface and the seafloor by a variety of mechanisms. As the...

Microstructural analysis with micro-scale based 40 Ar/ 39 Ar geochronology has been used to differentiate between different deformational events in the extensional zone of the central Agean Sea, Greece. North/south directed extension in the central Aegean has been largely accommodated by the...

Magnetic minerals are almost ubiquitous in nature, which means magnetic techniques can be used to understand Earth’s magnetic field and deep-Earth dynamo processes, and act as proxies for system processes in palaeoclimate, paleoceanography, pollution tracing, and archaeology.

Changes in mass balance (or the amount of ice that has melted) can be measured using space-geodetic techniques that detect variations in the Earth's gravity field and changes in ice height. Both satellite altimetry (used to measure ice topography heights) and GRACE (measures changes in potential) are sensitive to...

This project addresses the pressing need to understand the growing disequilibrium between today’s fast climate changes and slow ice-volume adjustments, which is significant because this is a key determinant for potential acceleration of sea-level rise. This is a major concern to society, because climate change and...

Signals transmitted from satellites orbiting the Earth are delayed as they pass through the troposphere of the Earth. This is measurable by GPS and so it is possible to measure how much water vapour is actually in the atmosphere using GPS. This is a new area of research that will involve the student learning about...

The Southern Ocean encircles Antarctica, dividing the polar regions from the warm tropical ocean. It is home to the world's strongest ocean current, the Antarctic Circumpolar Current, and is the primary location where ancient, deep ocean water is upwelled to the surface.  The Southern Ocean controls the natural...

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...

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...
