How seafloor weathering drives the slow carbon cycle

A previously unknown connection between geological atmospheric carbon dioxide cycles and the fluctuating capacity of the ocean crust to store carbon dioxide has been uncovered by two geoscientists from the University of Sydney. Prof Dietmar Müller and Dr Adriana Dutkiewicz from the Sydney Informatics Hub and the School of Geosciences report their discovery in the … Read more…

Models are as hot as rocks!

In a recent paper in JGR-Solid Earth, EarthByter Ömer Faruk Bodur and colleagues show that mantle lithosphere rheology has a primary control on the subduction style (i.e., one-sided vs. double-sided subduction) and strongly affects the pressure-temperature conditions of metamorphic rocks that can be buried >100 km depth and exhume to the surface! This long journey … Read more…

2018 supercomputing resources

The EarthByte group has been awarded 5.3 million computing hours, representing the equivalent of k$AU212, to carry out research for the Basin GENESIS Hub on the supercomputers Raijin (National Computational Infrastructure) and Magnus (Pawsey Supercomputing Centre) for 2018 through the National Computational Merit Allocation Scheme (4.7 MSUs) and the Intersect HPC Resource Allocation Round (600 kSUs).

Predicting Sediment Thickness on Vanished Ocean Crust Since 200 Ma

Citation: Dutkiewicz, A., Müller, R.D., Wang, X., O’Callaghan, S., Cannon, J., Wright, N.M., 2017. Predicting sediment thickness on vanished ocean crust since 200 Ma. Geochemistry, Geophysics, Geosystems, 18, 4586–4603. Tracing sedimentation through time on existing and vanished seafloor is imperative for constraining long-term eustasy and for calculating volumes of subducted deep-sea sediments that contribute to global … Read more…
