Background

Open-source projects

Tesseroids

Fatiando a Terra

Generic Mapping Tools

Inverse problems

Moho depth
from seismology

Assumpção et al. (2013)

Moho depth

Uieda & Barbosa (2017)
  • Spherical approximation
  • Fast computation
  • Estimate density
  • Tesseroids and Fatiando a Terra
  • Publish entire pipeline

Applications

  • Antarctica (Chisenga et al., 2019; Pappa et al., 2019)
  • Egypt (Sobh et al., 2019)
  • Atlas (Ghomsi et al., 2019)
  • China (Chisenga and Yan, 2019)
  • Cameroon (Ghomsi et al., 2020)

Data processing

sparse
observations

+
linear model

Predictions

  • Regular grids
  • Integrate datasets:
    GPS + InSAR
    ground + satellite gravity
  • Machine learning?
  • Scale to large(ish) data?
  • GRACE + field data?

Next generation
