Results for Apia observatory (API). a Map of bathymetry/topography; dashed line indicates location of profile shown in b. b West–East oriented bathymetry profile. c Regional depth-varying (purple) oceanic conductivity and constant reference oceanic conductivity (3.2 S/m, orange dashed line). dg Real and imaginary parts for x and y components of tippers computed in the model with depth-varying (red dots and dashed line) and depth-constant (orange dots and dashed line) oceanic conductivity. h Difference for the computed tipper x component between depth-varying and depth-constant ocean conductivity, see text for details. Dashed grey line indicates the threshold of 0.025. i Same as (h), but for the y component
