AuScope reviews innovations of the ARC Basin Genesis HUB

Sedimentary basins around the world are critical to sustaining modern life on Earth. These basins can be thought of as containers that hold water, minerals, energy, and can potentially be used to store carbon dioxide. Unpacking how they form, and where those resources and storage opportunities may lie is a sizeable feat for the best … Read more…

Atlas Obscura: Marine Snow Has Cooled the Planet with Dead Plankton for Millions of Years

The bodies of the tiny organisms lock away enormous amounts of carbon dioxide, and they’re in danger. The bottom of the Ocean holds one of the world’s largest and most populous graveyards. It’s crammed with organisms too tiny to see, including plankton, protists, and a type of marine algae called coccoliths. The continuous shower of bodies … Read more…

How marine snow cools the planet

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…

Australian-Antarctic breakup and seafloor spreading: Balancing geological and geophysical constraints

Abstract  The motion of diverging tectonic plates is typically constrained by geophysical data from preserved ocean crust. However, constraining plate motions during continental rifting and the breakup process relies on balancing evidence from a diverse range of geological and geophysical observations, often subject to differing interpretations. Reconstructing the evolution of rifting and breakup between Australia and Antarctica epitomizes the challenges involved in … Read more…
