The next EarthByte seminar will be held at 11am–12pm on Wednesday 16th November in Madsen Seminar Room 331 at the University of Sydney. This week we will be hearing from Ben Fulcher from the Dynamics and Neural Systems Group within the School of Physics at the University of Sydney, discussing his work on “Quantifying patterns in time series.” As usual, the seminar will be streamed live over Zoom at the following link: https://uni-sydney.zoom.us/j/82037433636.

AGU Science News: Billion-Year Rewind Tracks Supercontinents and Mantle Structures – EOS has featured our recent paper on tracing past pathways of tectonic plates and their boundaries back a billion years. The article highlights how our work on solid Earth system evolution is driving “a second plate tectonic revolution”., inspiring future work to test and … Read more…
The next installment of the EarthByte seminar series will be held at 11am–12pm next Wednesday 5th October, featuring Nick Mortimer from GNS Science in New Zealand. The seminar will be held in the Madsen Building Rm 449 at the University of Sydney, and streamed live on Zoom at this link: https://uni-sydney.zoom.us/j/82037433636.

Several theories have been proposed to explain atoll formation. While karst dissolution during glacial periods and preferential coral reef accretion along raised bank margins during deglaciations and interglacials have been invoked to explain atoll formation, the respective roles of karst dissolution and reef margin construction in atoll formation have not been adequately evaluated by simulations. … Read more…

Welcome to two new PhD students who have joined the EarthByte Group. Satyam Pratap Singh has joined the Stellar project working on reconstructions of palaeogeography through time and will be jointly supervised by Maria Seton, Sabin Zahirovic and Nicky Wright. Tom New has joined a recently funded ARC Discovery Project on plate-plume interactions and will … Read more…
The Cenozoic landscape evolution in southwestern North America is ascribed to crustal isostasy, dynamic topography, or lithosphere tectonics, but their relative contributions remain controversial. Here we reconstruct landscape history since the late Eocene by investigating the interplay between mantle convection, lithosphere dynamics, climate, and surface pro- cesses using fully coupled four-dimensional numerical models. Our quantified … Read more…
Modern ocean biodiversity, which is at its highest level ever, was achieved through long-term stability of the location of so-called biodiversity hotspots, regions of especially high numbers of species, scientists have found. The findings, published in Nature, were reached through a pioneering model that reconstructs the diversity of marine animals from their origin – some … Read more…
The fossil record of marine invertebrates has long fuelled the debate as to whether or not there are limits to global diversity in the sea. Ecological theory states that, as diversity grows and ecological niches are filled, the strengthening of biological interactions imposes limits on diversity. However, the extent to which biological interactions have constrained … Read more…
Understanding the long-term evolution of Earth’s plate-mantle system is reliant on absolute plate motion models in a mantle reference frame, but such models are both difficult to construct and controversial. We present a tectonic rules-based optimisation approach to construct a plate motion model in a mantle reference frame covering the last billion years and use … Read more…
How can the sluggish, long-wavelength mantle convection be expressed by so many time and space scales of morphotectonic activity? To investigate these relationships, we explore the Java-Banda subduction zone, where geodynamic records cluster. In the far-East Tethys, the exceptionally arcuate Banda subduction zone circumscribes the deepest oceanic basin on Earth, seismotectonic activity slices the upper … Read more…
The lithospheric build-up of the African continent is still to a large extent unexplored. In this contribution, we present a new Moho depth model to discuss the architecture of the three main African cratonic units, which are: West African Craton, Congo Craton, and Kalahari Craton. Our model is based on a two-step gravity inversion approach … Read more…
PyBacktrack 1.4 is now available, and adds support for generating paleobathymetry grids from submerged present-day crust. PyBacktrack is available as a Python package and a Docker image. Installation instructions can be found online in the pyBacktrack documentation. Changes since version 1.3: Can now generate paleobathymetry grids: Submerged oceanic and continental present-day crust is backtracked and … Read more…

Welcome Matthew Merkas and Yiyan Wang to the EarthByte Group! They will work with Maria Seton and Michael Chin on “GPlates In Schools” mobile app. The “GPlates-in-schools” program is funded by AuScope, comprising a GPlates app with integrated lesson plans, to provide an Earth Science-focused education engagement initiative. Matthew is an app developer in the EarthByte … Read more…
