Our geodynamics collaborators from the Augury Geodynamics Group, Univ. Lyon, are spending the month of December 2016 with the EarthByte Group to collaborate on a range of issues revolving around seeking improved connections between kinematic (plate tectonic) and dynamic Earth models to advance our understanding and knowledge of the evolution of the solid Earth and the “rules of plate tectonics”. Even though some basic rules of plate tectonics have been accepted since the 70s, these rules are not extensive enough to understand the dynamic, time-dependent interaction between the convecting mantle and the tectonic plates. The visit is inspired by the move towards Plate Tectonics 2.0 – the development of a unified conceptual and methodological framework to understand how the shallow crust, landscapes, continental margins, and ocean basins interact with the coupled non-linear evolution of the plates and deep Earth through time.
GPlates 2.0 was released last week, with lots of new features including plate deformation, volume rendering, much improved project and session management, a plate topology building tool and an interactive tool to determine best-fit rotation poles using the method of Hellinger, and much more. Check out the full list of improvements here. … Read more…

It’s really an award for all EarthByters! … Read more…
GPlates is a free desktop software for the interactive visualisation of plate-tectonics. The compilation and documentation of GPlates 2.0 data was primarily funded by AuScope National Collaborative Research Infrastructure (NCRIS).
GPlates is developed by an international team of scientists and professional software developers at the EarthByte Project (part of AuScope) at the University of Sydney, the Division of Geological and Planetary Sciences (GPS) at CalTech, the Geodynamics team at the Geological Survey of Norway (NGU) and the Centre for Earth Evolution and Dynamics (CEED) at the University of Oslo. … Read more…

Greetings from the surface processes workshop using the open-source Badlands code developed by our very own Tristan Salles as part of the Basin GENESIS Hub. Today we covered how to use Docker/Kitematic to download the pyBadlands virtual machine and run the examples (mountain building, delta formation, and so on). … Read more…
Jiabao Zhang, bachelor student at the University of Geosciences in Wuhan, China, visited the Basin Genesis Hub for a month in September 2016 to practice numerical modelling in geomorphology under the supervision of Dr Gilles Brocard and Dr Tristan Salles. … Read more…
EarthByte Welcomes new PhD candidate Ömer Bodur.
Date: August 29 – 30 2016 Venue: The University of Sydney Description: A two-day workshop bringing together climate and geo-scientists from around Sydney and international collaborators on the DCO-funded Deep Carbon Modelling project. Deep carbon science describes the multi-disciplinary effort to unravel the dynamic interactions of carbon-bearing systems in deep time. The workshop will focus on exploring the interplays … Read more…
Congratulations Adriana Dutkiewicz, Dietmar Müller, Andrew Hogg, and Paul Spence for their recent paper published in Geology. Their paper, Vigorous deep-sea currents cause global anomaly in sediment accumulation in the Southern Ocean, revealed an enormous stretch of the Southern Ocean where sediments are building up at a rate that dwarfs other deep ocean locations. The work has attracted the attention of media internationally. … Read more…
A team led by the University of Sydney School of Geosciences has found an 8,000-km long sediment pile-up in the middle of the Southern Ocean, making this feature unique in the world. Their study was published today in the leading international journal Geology. … Read more…
Congratulations to Dr Sascha Brune, Dr Simon Williams, Dr Nathan Butterworth, and Prof Dietmar Müller on their paper published in Nature earlier this week. The paper, Abrupt plate accelerations shape rifted continental margins, has been picked up by the media across the globe.

Welcome back to the geoscience crew from the ECOSAT II voyage on the RV Investigator! After braving close to 10 meter high waves and over 50 knot winds on their approach into Hobart, the team made it back safely with an impressive haul of rocks, geophysical data and the experience of a lifetime. … Read more…
Every now and then in Earth’s history, a pair of continents draws close enough to form one. There comes a time, however, when they must inevitably part ways. Now scientists at Australia’s EarthByte research group, in collaboration with the German Research Centre for Geosciences, have revealed the underlying mechanics of a continental breakup when this … Read more…
Recently the Australian geoscience community celebrated a decade of AuScope achievements. EarthByte’s very own Prof Dietmar Muller was an award finalist for excellence in scientific research and providing tools (such as GPlates) that enable scientific development in our community. GPlates is an open-source and cross-platform tool that is accessible to high school teachers, research scientists and anyone … Read more…
PhD Candidate Nicky Wright is currently in Italy attending The 13th Urbino Summer School in Paleoclimatology. The summer school aims to provide early-career researchers with advanced working knowledge on paleobiological and geochemical proxy data and their use in reconstructing and modelling of past climate.

Plate tectonics drives earthquakes and volcanism, forms precious mineral deposits and controls the planet’s long-term carbon cycle. But why do we have just a few large plates, and many tiny plates? Does it matter? These questions have now been answered in a French-Swiss-Australian collaborative paper led by PhD student Claire Mallard at the Univ. Lyon, published on 15 June 2016 in the journal Nature. The paper includes Nicolas Coltice (Lyon), EarthByters Dietmar Müller and Maria Seton, and Paul Tackley (ETH).

In a paper published in Nature, Rakib Hassan with fellow EarthByters Dietmar Müller, Simon E. Williams & Nicolas Flament, and Caltech’s Michael Gurnis, proposed a solution to a long standing geological mystery – how the distinct bend in the Hawaiian-Emperor Seamount Chain came to be. Using NCI’s Raijin supercomputer, the research team simulated flow patterns in the Earth’s mantle over the past 100 million years. The convection model suggests that the history of subduction has a profound effect on the time-dependent deformation of the edges of the Large Low-Shear Velocity Province (LLSVP) under the Pacific. The Hawaiian plume originates from the edge of this province and the southward migration of the plume during the formation of the Emperor chain reflects the migration of the northern edge of the LLSVP before ~47 million years ago.
