Map of the geodetic network on the seafloor. Baseline shortening or lengthening rates, based on the total deformation measured at the end of the deployment, are colour coded. A constant strain of 4.5 × 10−6 was subtracted to each baseline in order to correct for the inferred constant salinity decrease of 0.002 PSU yr−1. Transponder locations are shown as black circles. F- and G- stations only communicate within their respective network. High-resolution shaded bathymetry map26,27 is shown with a light source from the South
