Climatic variability like precipitation changes or increase in extreme events such as storms and tropical cyclones is known to significantly modify the Earth’s surface. Yet, our understanding of how sediment dynamics and reef evolution might respond to these changes is still limited. In a recent study, a team of researchers from the University of Sydney’s … Read more…

Geological Magazine, 1-24. Abstract: Whether the latitudinal distribution of climate-sensitive lithologies is stable through greenhouse and icehouse regimes remains unclear. Previous studies suggest that the palaeolatitudinal distribution of palaeoclimate … Read more…

In a recent paper in JGR-Solid Earth, EarthByter Ömer Faruk Bodur and colleagues show that mantle lithosphere rheology has a primary control on the subduction style (i.e., one-sided vs. double-sided subduction) and strongly affects the pressure-temperature conditions of metamorphic rocks that can be buried >100 km depth and exhume to the surface! This long journey … Read more…
The EarthByte group has been awarded 5.3 million computing hours, representing the equivalent of k$AU212, to carry out research for the Basin GENESIS Hub on the supercomputers Raijin (National Computational Infrastructure) and Magnus (Pawsey Supercomputing Centre) for 2018 through the National Computational Merit Allocation Scheme (4.7 MSUs) and the Intersect HPC Resource Allocation Round (600 kSUs).
By Alison Snyder, AXIOS We have a more accurate map of the surface of Mars than we do for Earth’s ocean floor. Right now, researchers have a blurry, indirect picture of the seabed from satellite imaging, some sonar data and samples collected from ships. Yes, but: There’s an avalanche of data about the chemical, physical and … Read more…

As a greenhouse gas, carbon dioxide in the atmosphere has played a major role in regulating Earth’s climate throughout its history. There are vast stores of carbon in the subsurface, but the global carbon cycle controls how much of that carbon enters the atmosphere. As methods for monitoring and tracking the carbon dioxide that moves … Read more…

Currently, human activity is the primary driver of elevating atmospheric CO2, but the Earth fluctuated from greenhouse to icehouse conditions and back long before humans existed. The question is: what triggered these long-term climate cycles? Now research at the University of Sydney’s EarthByte Group, in collaboration with the German Research Centre for Geosciences, reveals how … Read more…

Lauren Harington from School of Geoscience and EarthByte Group gives presentation a Seminar on her Honours project “Modelling the evolution of the Eromanga Sea in the context of tectonics, geodynamics and surface processes” Watch full presentation here: Link ABSTRACT: The Eromanga Sea is an epeiric, epicontinental seaway that dominated the eastern Australian landscape during the Cretaceous. Previous … Read more…
Deep Carbon Observatory member, Sabin Zahirovic explains why the Earth is like a giant, spherical lava lamp. The intense heat at the core drives plumes of mantle material up to the cooler surface where it solidifies as part of tectonic plates. Over geologic timescales, the edges of those plates eventually sink back into the mantle in … Read more…
The University of Sydney has committed to transformational investments in our research infrastructure resulting in a rapidly increasing demand for new and innovative software to capture, create, and analyse data.
