How marine snow cools the planet

by

University of Sydney scientists have modelled how carbonate accumulation from ‘marine snow’ in oceans has absorbed carbon dioxide over millennia and been a key driver in keeping the planet cool for millions of years. Researchers in the School of Geosciences have mapped out how carbonate formations have helped regulate Earth’s temperature over 120 million years. … Read more…

Does the sea level or the sun drive volcanic seafloor topography?

by

Modelling shows what causes abyssal hills 2.5km below sea level Computer modelling shows climate- and sea-level cycles are not responsible for the ‘hills’ and ‘valleys’ at the bottom of the sea – a hypothesis that would have mapped a path to uncovering Earth’s climate history.

Zealandia: Earth’s Hidden Continent

by

ZealandiaA paper published in GSA Today, Zealandia: Earth’s Hidden Continent, by Nick Mortimer and colleagues, including EarthByte’s Dr Maria Seton, has gone viral over the last few days. In the paper, researchers have for the first time clearly defined Zealandia, a continent that includes New Zealand, New Caledonia, and the Lord Howe and Norfold Islands, that is today 94% submerged beneath the Pacific Ocean. According to GSA Today’s editors, the article is “by a long shot” their most downloaded article ever. Picked up by hundreds of media outlets worldwide, the findings of the paper has reached an estimated 720 million readers!

The pains and strains of a continental breakup

by

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.

Solving Earth’s giant jigsaw puzzle of tectonic plates

by

plate-tesselation
Earth’s plate tesselation through time (150 Myr ago to present)

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).

How the Hawaiian-Emperor seamount chain got its spectacular bend

by

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.

Geologists Discover How Australia’s Highest Mountain Formed – Media Release

by

Eastern_australia_topographyGeologists from the University of Sydney and the California Institute of Technology have solved the mystery of how Australia’s highest mountain – Mount Kosciusko – and surrounding alps came to exist.

Most of the world’s mountain belts are the result of two continents colliding (including the Himalayas) or volcanism. The mountains of Australia’s Eastern highlands – stretching from north-eastern Queensland to western Victoria – are an exception. Until now no one knew how they formed.

Virtual Time Machine Of Earth’s Geology Now In The Cloud

by

gravity_grid_180my_agoHow 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.
