Volcanoes, geysers and earthquakes! – 89.7 Eastside FM

A recent trip to Iceland piqued Sylvia’s curiosity about nearly every geological feature she saw. Back in Sydney, she explored those features – volcanoes, geysers, earthquakes, tectonic plates – with Dietmar Muller, Professor of Geophysics at the University of Sydney. That conversation went to air on Arts Wednesday 16 August 2017 and you can listen … Read more…

The Encyclopedia of Marine Geosciences

The Encyclopedia of Marine Geosciences was selected for the 2017 Mary B. Ansari Best Geoscience Research Resource Work Award of The Geoscience Information Society (GSIS). The formal award will be given at the GSA 2017 conference in October in Seattle/USA. EarthByters Dietmar Muller and Maria Seton contributed two chapters on “Paleophysiography of Ocean Basins” and “Plate Motion”. This Encyclopedia … Read more…

Rock solid insights deepen our understanding of the world

Final year undergraduate student, Madison East is based in the School of Geosciences EarthByte Group, a leading international collaboration between Australian universities, industry partners and centres of excellence. “I began a research scholarship with Dietmar Müller and the EarthByte Groupin the summer of 2016/17 looking at how subduction zones have evolved since the Jurassic,” said … Read more…

Global patterns in Earth’s dynamic topography since the Jurassic: the role of subducted slabs

Abstract: We evaluate the spatial and temporal evolution of Earth’s long-wavelength surface dynamic topography since the Jurassic using a series of high-resolution global mantle convection models. These models are Earth-like in terms of convective vigour, thermal structure, surface heat-flux and the geographic distribution of heterogeneity. The models generate a degree-2-dominated spectrum of dynamic topography with … Read more…

Summer Projects 2017/2018

EarthByte globe icon

Available Summer Scholarships Applications from 2nd or 3rd year University of Sydney students studying geoscience are invited to apply for summer scholarship positions with EarthByte. These projects bring undergraduate students into active research projects, and provide valuable insight into the inner workings of dynamic teams working on real-world problems. Research projects run for a duration … Read more…

Tectonic speed limits from plate kinematic reconstructions

Abstract The motion of plates and continents on the planet’s surface are a manifestation of long-term mantle convection and plate tectonics. Present-day plate velocities provide a snapshot of this ongoing process, and have been used to infer controlling factors on the speeds of plates and continents. However, present-day velocities do not capture plate behaviour over … Read more…

Summer Vacation Internships with Chevron.

Applications are invited for summer internships with Chevron. The program offers students the opportunity to work collaboratively with a team to discover new energy reserves by focusing on a producing field or exploration project. The intake is from late November to February (12 Weeks) during the summer vacation period. The work will be paid, with … Read more…

Earth is estimated to be around 4.5 billion years old, with life first appearing around 3 billion years ago.

EarthByter Andrew Merdith, Alan Collins from the Univ. of Adelaide and colleagues produced an animated plate tectonic map that changes the history of our planet as we know it. Of course it’s not just an animation, it’s an elaborate computer model that took years to be built, assimilating tons of geological and geophysical observations, in a … Read more…

The deep Earth origin of the Iceland plume and its effects on regional surface uplift and subsidence

Abstract The present-day seismic structure of the mantle under the North Atlantic Ocean indicates that the Iceland hotspot represents the surface expression of a deep mantle plume, which is thought to have erupted in the North Atlantic domain during the Palaeocene. The spatial and temporal evolution of the plume since its eruption is still highly … Read more…
