Solid Earth carbon degassing and sequestration since 1 billion years ago

Solid Earth CO2 outgassing, driven by plate tectonic processes, is a key driver of carbon cycle models. However, the magnitudes and variations in outgassing are poorly constrained in deep-time. We assess plate tectonic carbon emissions and sequestration by coupling a plate tectonic model with reconstructions of oceanic plate carbon reservoirs and with a thermodynamic model … Read more…

Our longest-serving EarthByte Group research assistant, Lauren Ilano, has recently been awarded the Peter Fountain Award together with Caelan Hearne in memory of Peter Fountain, who was a beloved Maritime industry legend with PIANC Australia & New Zealand.  The award supports outstanding young engineers in their careers as well as their attendance at the PIANC … Read more…

Mars attracts: how Earth’s planetary interactions drive deep-sea circulation

12 March 2024, The University of Sydney Media Release Giant whirlpools in warming oceans could mitigate Gulf Stream stagnation Geoscientists at Sydney and Sorbonne have identified a 2.4-million-year cycle in the geological record that show the energy of deep-sea currents wax and wane as oceans cool and warm. Earth’s distance to Mars varies between 55 … Read more…

Geology: Duration of Sturtian “Snowball Earth” glaciation linked to exceptionally low mid-ocean ridge outgassing

The Sturtian ‘Snowball Earth’ glaciation (~717–661 Ma) is regarded as the most extreme interval of icehouse climate in Earth’s history. The exact trigger and sustention mechanisms for this long-lived global glaciation remain obscure. The most widely debated causes are silicate weathering of the ~718 Ma Franklin LIP, and changes in the length and degassing of … Read more…

Deep time spatio-temporal data analysis using pyGPlates with PlateTectonicTools and GPlately

Plate Models

PyGPlates is an open-source Python library to visualize and edit plate tectonic reconstructions created using GPlates. The Python API affords a greater level of flexibility than GPlates to interrogate plate reconstructions and integrate with other Python workflows. GPlately was created to accelerate spatio-temporal data analysis leveraging pyGPlates and PlateTectonicTools within a simplified Python interface. This … Read more…

GPlately1.0 released

GPlately

We have just released GPlately1.0 as a conda package. GPlately was created to accelerate spatio-temporal data analysis leveraging pyGPlates and PlateTectonicTools within a simplified Python interface. GPlately is a python package that enables the reconstruction of data through deep geologic time (points, lines, polygons and rasters), the interrogation of plate kinematic information (plate velocities, rates of subduction … Read more…

STELLAR – Spatio TEmporaL expLorAtion for Resources

stellar_logo_light

Project STELLAR (Spatio TEmporaL expLorAtion for Resources) is a collaboration between BHP and the EarthByte Group aimed at implementing big and complex spatio-temporal data analysis and modelling to support the needs of BHP in global resource exploration. Split into multiple phases over the next 3.5 years, the project will connect BHP’s warehouse of global resource knowledge with … Read more…
