Reliable monitoring programs to detect tests conducted in secret are a key component in the fight for non-proliferation of nuclear weapons. International groups such as the Comprehensive Nuclear-Test-Ban Treaty Organization are tasked with running global networks of instruments capable of Read More …
This article provides a brief overview of the motivation and results of our study on MPWP sea level that’s just been published in Science Advances. As the concentration of greenhouse gasses in the atmosphere continues to increase, melting of polar Read More …
I am very excited to be starting a new postdoc this April at the Australian National University in Canberra! My position is based at the Research School of Earth Sciences and involves working closely with both the Geodynamics group of Read More …
Like most people, March 2020 brought about a sudden shrinking of my world that took some serious getting used to. Initially, I buried myself in work and was lucky enough to achieve a lot, but by July it was definitely Read More …
Ocean basins cover two-thirds of our planet’s surface. They are made of oceanic lithosphere, which is continuously being created from upwelling asthenospheric mantle at mid-oceanic spreading ridges, and destroyed at subduction zones where it sinks back into the mantle. This Read More …
The theory of plate tectonics states that Earth’s surface is made up of several internally rigid plates that coherently translate across the underlying mantle, pulling apart to build new ocean basins and crashing into one another to form mountain belts Read More …
The theory of plate tectonics has proven highly successful at explaining the distribution of mountain belts, oceanic basins, volcanoes, and earthquakes. These features generally form linear chains along the boundaries of the plates, with significantly less geological activity occurring within Read More …
This article outlines the motivation behind and summarises results from our Nature Geoscience study Global distribution of sediment-hosted metals controlled by craton edge stability. You can download a free preprint here. The societal importance of base metals Copper, lead, and Read More …
Convective circulation of the mantle causes vertical deflections of Earth’s surface of up to ±2 km. As the planform of convection evolves over millions of years, the pattern of these deflections also changes, which is why we call this phenomenon Read More …
Transfer of heat through the Earth is accommodated by the slow creeping of solid rock. The mantle can move thousands of kilometers in the millions of years it takes for supercontinents to break apart and species to evolve. Forming a Read More …
