Climate change is having lasting effects such as changing ocean acidity, temperatures, and heights, increasing the chances of natural hazards such as forest fires and hurricanes, and leading to the disappearance of water sources supplied by glaciers and snow. Carbon dioxide (CO2) produced by humans is a primary contributor to man-made climate change thus finding storage mechanisms for human produced CO2 is necessary to mitigate climate change. Mantle rocks, like peridotite, offer a storage option for CO2. In the presence of water, peridotite will alter into new kinds of rocks. If CO2 is present in the water, this CO2 will be stored as a solid in the rocks, keeping it trapped underground forever. Currently, this chemical alteration process is well understood, however the physical process that allows water to reach unaltered peridotite is not. Given that mantle rocks like peridotite are common, this could feasibly be used to store a large fraction of human produced CO2.
The Oman Drilling Project Multi-Borehole Observatory has collected a large amount of data (>10TB) including geological and petrological data such as borehole core images, x-ray tomography, physical and chemical characteristics of host rock in the region, and also time series data such as acoustic emissions, temperature, and borehole water pressure. Using this data to understand peridotite alteration will require an interdisciplinary computational approach. SerpRateAI will use this data along with modern AI and ML tools to discover the physical processes that allow water to be pumped underground to understand how peridotite alters. This talk will present the ongoing work towards these goals and present the future effort.
Program
11:30 – Doors open and lunch is served
12:00 – "Constraining Peridotite Alteration Rates with AI and ML" by John Aiken (Researcher, NJORD Centre for Studies of the Physics of the Earth)
This event is open for all PhD candidates and postdocs. No registration needed.
About the seminar series
Once a month, dScience will invite you to join us for lunch, soft drinks and professional talks at the Science Library. In addition to these, we will serve lunch to PhD candidates in our lounge in Kristine Bonnevies hus every Thursday. Due to limited space (40 people), this will be first come, first served. See how to find us here (download).
Our lounge can also be booked by PhDs and Postdocs on a regular basis, whether it is for a meeting or just to hang out – we have fresh coffee all day long! Read more about the seminar series here.
