Title: An Interactive workflow for MT data using open-source packages and HPC

Presenters: Jared Peacock (USGS) and Karl Kappler (DIAS Geophysical and Space Science Institute)

Date and time: 4pm (AEST time), 23rd Nov 2023


The magnetotelluric (MT) community has traditionally been composed of specialists, however with the advancement of accessibility to equipment, data, and high-performance computing more non-specialists are interested in MT data.  Open-source tools exists for working with MT data; however no publicly available coherent workflow exists.  We present a workflow for MT data that demonstrates how to use existing open-source software packages to go from raw data to a 3D resistivity model. This workflow increases the capacity of MT data to be used for open science following FAIR principles.


  1. Jared Peacock is a research geophysicist at the Geology, Minerals, Energy, and Geophysics Science Center in Menlo Park, CA. He received his Ph.D. from the University of Adelaide and B.Sc. and M.Sc. from the Colorado School of Mines, all in geophysics. Since joining the USGS In 2013, his expertise is in magnetotellurics, focusing on characterizing volcanic, geothermal, and mineral systems in 3D.
  2. Karl Kappler has held roles in the development of remote sensing and digital data processing technologies, mostly in electromagnetics and acoustics with applications ranging from unexploded ordnance, resource exploration, and borehole investigations to measurements while drilling. Karl received MS and PhD degrees in Engineering Geoscience from the University of California at Berkeley after completing a BSc in Mathematics and Physics at the University of Victoria.  Karl is an active contributor to MTH5, mt_metadata and the main developer of aurora, hosted by UBC’s SimPEG. Karl currently acts in the role of Magnetotelluric Specialist within DIAS Geophysical's R&D team in his native Canada and is also an Affiliate Research Scientist at the Space Science Institute in the USA."
