GeoOnsdag: Reading Earth´s hard drive

Welcome to the talk "Reading Earth´s hard drive", by Associate Professor at Department of Geosciences Mathew Michael Domeier.
Magnetic storage systems, such as conventional hard disk drives, store information (e.g. documents, images, music) as encoded permanent magnetizations. Remarkably, rocks can store magnetic information in a similar way, and they preserve encoded signals written by the Earth itself. But what information do these signals contain, and how can we decode them? In this talk we will explore how we can read Earth's paleomagnetic 'hard drive' and apply the information recovered to-among other things-date the oceanic crust, reveal the past motions of continents, and study processes that occurred in Earth's deep interior in the distant past.
Mathew Domeier is a geophysicist whose research focuses on Earth's paleogeographic and geomagnetic evolution. He holds a PhD from the University of Michigan (USA) and has been at the University of Oslo since 2012. He has worked in 3 Norwegian Centres of Excellence and is currently affiliated with the Centre for Planetary Habitability. Mathew has been an Associate Professor since 2022 and presently leads an ERC Consolidator project dedicated to understanding paleomagnetic records from the Ediacaran period.
___________________________
Once a month, researchers at the Department of Geosciences, University of Oslo, will tell about their research and introduce the geociences to a wide audience, from first-year undergraduates, colleagues to interested in general. It is possible to ask questions after the lectures.
Coffee/tea are served. Everyone is welcome!
The lectures are streamed. You can watch the stream at Realfagsbibliotekets TH-cam-channel.
