  1. Existing inversion with tesseroids (Chaves and Ussami, 2013) • Geoid

    height anomalies • Space domain • Regularization: – Depth-weighted Minimum Volume – Similarity to seismic tomography
  2. Planting anomalous densities • Space domain • Multicomponent: gravity +

    gradients • Non-conventional inversion – Growth algorithm – No linear systems – Efficient sensitivity computations
