As a part of the 2020 EarthCube annual meeting, we held a Jupyter meets the Earth community discussion session on July 27. The Jupyter meets the Earth project is an EarthCube funded effort that combines research use cases in geosciences with technical developments within the Jupyter and Pangeo ecosystems. In this model of equal partners, scientific questions help drive software infrastructure development, and new technologies expand the horizons of viable research. …

Lindsey Heagy, Joe Capriotti, and the SimPEG team

We merged a big pull request into SimPEG this week (#786): over 30,000 lines of code changed! (and now close to 60,000 because we ran black 😉) These changes have been in progress since Summer 2019 and involved input, feedback, contributions, and improvements from many in the team. …

We are thrilled to announce that the NSF is funding our EarthCube proposal “Jupyter meets the Earth: Enabling discovery in geoscience through interactive computing at scale” (pdf). The team working on this project consists of Fernando Pérez [1, 2, 3], Joe Hamman [4], Laurel Larsen [5], Kevin Paul [6], Lindsey Heagy [1], Chris Holdgraf [1, 2] and Yuvi Panda [7]. Our project team includes members from the Jupyter and Pangeo communities, with representation across the geosciences including climate modeling, water resource applications, and geophysics. Three active research projects, one in each domain, will motivate…

SimPEG team in Montreal!

Last week, the International Union of Geodesy and Geophysics conference was held in Montreal and the SimPEG team took the opportunity to hold a 1-day meeting for those of us attending. Six of us (Dom Fournier, Doug Oldenburg, Joe Capriotti, Seogi Kang, Thibaut Astic and myself) got together to discuss a roadmap for working towards SimPEG 1.0! We broadly covered 4 topics:

  • Simulation refactor: Refactoring the Problem and Survey classes in SimPEG to a Simulation class and a lighter-weight Survey class
  • Sources and receivers: Thinking through the structure of the source and receiver classes to reduce redundancy…

Following DISC Lab day in Buenos Aires, we hopped on a plane and landed in Santiago, Chile late on Tuesday night. By the time we arrived at our airbnb in the heart of Santiago, it was Wednesday. It was a bit eerie arriving so late in an unfamiliar city, seeing stray dogs running around, and not being entirely sure where our accommodation was. However, when we woke up the next morning, we looked out the window, saw the view captured in the above image, and were please to be situated in a bustling part of the city.

Craig Miller, Seogi Kang and Dom Fournier had their paper: Distribution of vapour and condensate in a hydrothermal system: Insights from self-potential inversion at Mount Tongariro, New Zealand, accepted this week!

Volcanologists routinely sample fluids from springs and vents on volcanoes to determine that volcano’s state of unrest. Prior to the 2012 Te Maari eruptions at Mt Tongariro, New Zealand, changes in water and gas chemistry that preceded the eruption, were found at only a few of the vents and springs sampled, despite evidence for a large hydrothermal system, thought to connect them. We wanted to…

Dom has been working on making changes to the SimPEG Regularization for the new formulation of the TreeMesh including add functionality for mesh creation and refinement. The updates are included in pull request #708. This will be the topic of the upcoming SimPEG meeting.

Lindsey Heagy: I have been working on writing up some of the early PhD work I did on estimating the conductivity of a fractured volume of rock for a fracture operation with an electrically conductive proppant (particles used to keep the fractures open) and fluid. We approach it in 2 steps: (1) estimate the effective conductivity of a mixture of proppant and fluid, (2) estimate the (isotropic or anisotropic) conductivity of a fractured volume of rock filled with the conductive mixture. …

The morning after DISC Lab in Mexico City, we hopped on a flight to the Southern Hemisphere. Nine hours later, we landed in Buenos Aires. Buenos Aires is a city that is alive with music, tango, and festivals. Being spring, the Jacarandas were in bloom, giving a pop of purple to the city streets.
