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…
Sam Illingworth, a Senior Lecturer in Science Communication, Manchester Metropolitan University, wrote a science poem inspired by our recent research on how ‘marine snow’ has helped to regulate Earth’s temperature over the last 120 million years. A great example of the connection between science and art. The entire piece can be read here.
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…
Jo’s wide-ranging interview covers how Dietmar got into geology, why plate-mantle interaction is like biscuits floating on warm toffee, and what role AuScope has played in the success of the EarthByte Group. Read more here.
In January 2019 Peter Spinks taught a media workshop for the Basin Genesis Hub at the University of Sydney. Topics covered included why it’s important to communicate with the public, stakeholders and the media, the value system involved, “getting the picture”, i.e. preparing graphics, illustrations, photographs and videos, popular science writing 101, media releases and … Read more…

Tectonic plates lost to the deep mantle carry a record of ancient surface tectonic processes. A method for retrieving such records has been developed that could clarify the links between tectonics and mountain building. The Andes are the longest continental mountain chain on Earth and the highest outside of Asia. This chain of rocky spires … Read more…

A news article published by the Deep Carbon Observatory entitled “Mapping the Growth of Seafloor Carbonates in Deep Time” explains how Adriana Dutkiewicz and colleagues used records of carbonate layers logged from cores collected during scientific ocean drilling expeditions combined with a model of ocean basin evolution to unravel the role deep sea carbonate deposition might have … Read more…
In the piece, Patrice recalls some of his own experiences as a kid when he first encountered mountain building. He wrote: “Hello Astrid. You may not believe this but when I was about your age my teacher (Mr Rouve) explained to the class how mountains get made. He took a sheet of paper and put … Read more…
Roberto Spina, a computational geologist from Italy, wrote a lead article in GSA Today, in which he reviews the future of Big Data and Artificial Intelligence Analytics in Geosciences, using Adriana Dutkiwicz’s digital seafloor lithology map published 3 years ago as a ground-breaking example. The article includes a South Atlantic view of the virtual globe portraying her map, … Read more…
Ready for a fresh start in 2019, our web development guru Michael Chin has created a new interactive virtual gravity globe, based on BGI’s global gravity grids by Bonvalot et al. (2012). The virtual globe allows the user to visualise either Bouguer or isostatic gravity anomalies. The latter has both the effect of surface and … Read more…
Congratulations to Sabin Zahirovic for receiving an Emerging Leader Award for his work with an international and interdisciplinary Deep Carbon Observatory team investigating links between the evolution of our planet and the exchange of carbon between Earth’s interior and the surface. He was independently nominated by a total of 5 DCO members from 4 countries! Sabin will receive AU$2,000 … Read more…
The Alfred P. Sloan Foundation recently announced two new Officer’s Grants for deep carbon science, supporting important community building and modeling efforts.

Abstract The extent of continental rifts and subduction zones through deep geological time provides insights into the mechanisms behind supercontinent cycles and the long term evolution of the mantle. However, previous compilations have stopped short of mapping the locations of rifts and subduction zones continuously since the Neoproterozoic and within a self-consistent plate kinematic framework. … Read more…
EarthByte would like to welcome Edward Clennett from the University of Oxford who is visiting us for 5 weeks to work on his masters project. During his visit, he plans on developing a new plate reconstruction model of the north-eastern Pacific and western North America using tomographic constraints and terrane accretion events. He will also … Read more…
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…
