Short title: Synthetic test Detailed legend: a Conductivity profiles and b corresponding tippers for TDC bathymetry are shown for two synthetic conductivity profiles: a homogeneous Earth model [(HOM, dashed gray line (a) and dashed colored lines (b)], and a profile varying with depth (1-D, red line (a) and symbols (b)). The synthetic tippers that correspond to the 1-D profile were inverted with 3% added noise and resulted in a the solid black conductivity profile and b the tippers shown by solid colored lines
