Interactive Geophysics

Lindsey Heagy and Rowan Cockett

In the deployment of a short-course on electromagnetic geophysics, we have been developing strategies for developing an “educational stack.” Web-based textbooks and interactive simulations built using Jupyter notebooks provide an entry-point for course participants to reproduce content they are shown and to dive into the code used to build them. Our overarching aim is to make the geophysical concepts accessible and interactive: from first introduction, to research and applied work. We will share the tools we are using and discuss some of our learnings.

1. Interactive Geophysics Lindsey Heagy, Rowan Cockett & GeoSci Team SciPy July 13, 2017 @lindsey_jh, @rowancockett
2. • Signal processing • Numerical simulations • Finite volume • Optimization • Regularization Geophysics? Interactive?
3. last year... Working towards all of the geophysics - but backwards Using open source tools to refactor geoscience education
4. last year... http://geosci.xyz
5. so, as we were saying...
6. Goals • Inspire ◦ See variety of applications through case histories • Build a foundation ◦ Basic principles of EM ◦ Set realistic expectations of EM • Promote development of an EM community Dr. Doug Oldenburg http://disc2017.geosci.xyz
7. Audience • Industry professionals ◦ Geologists ◦ Geophysicists ◦ Engineers • Researchers • Graduate students Dr. Doug Oldenburg, http://disc2017.geosci.xyz
8. for example Jump in here (~1.5 hrs into course) intro
9. Applications intro for example mineral exploration Water inflow into mine groundwater
10. for example http://notebooks.azure.com/library/em_apps • DC_Cylinder_2D.ipynb
11. DC Resistivity for concept in geophysics: app(concept) Frequency Domain EM Natural Sources Time Domain EM https://notebooks.azure.com/library/em_apps
