EarthByte welcomes new PhD student Rhiannon Garrett.
Bon voyage! Today, a group of scientists, headed by Dr. Simon Williams from the School of Geosciences, have boarded Australia’s state-of-the-art marine research vessel, the , for a 14-day voyage. The voyage departed from Lautoka, Fiji and is currently headed towards the Fairway Ridge, an uplifted but submerged part of the Lord Howe Rise, northwest of New Caledonia. … Read more…
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.

The recent article on the GPlates Portal published in PLOS ONE by Prof Dietmar Müller, Xiaodong Qin, Prof David Sandwell, Dr Adriana Dutkiewicz, Dr Simon Williams, Dr Nicolas Flament, Dr Stefan Maus, and Dr Maria Seton, has received significant international media attention over the past week, featuring in articles from Australia, UK, US, India, and UAE!
See the list of online media below, and check out the interactive globes yourself!
How did Madagascar once slot next to India? Where was Australia a billion years ago?
Cloud-based virtual globes developed by a team led by University of Sydney geologists mean anyone with a smartphone, laptop or computer can now visualise, with unprecedented speed and ease of use, how the Earth evolved geologically.
Reported today in PLOS ONE, the globes have been gradually made available since September 2014. Some show Earth as it is today while others allow reconstructions through ‘geological time’, harking back to the planet’s origins.
Uniquely, the portal allows an interactive exploration of supercontinents. It shows the breakup and dispersal of Pangea over the last 200 million years. It also offers a visualisation of the supercontinent Rodinia, which existed 1.1 billion years ago. Rodinia gradually fragmented, with some continents colliding again more than 500 million years later to form Gondwanaland.
