Map showing the stations deployed so far and the remaining stations to be deployed in the coming days. The map shows a wealth of information about the area known as St Paul and Romanche Fracture Zones across the mid-Atlantic Ridge. The different shaded ocean bottom shows the depth-varying bathymetry; red shade indicates shallow water (still deeper than 1,500 m) – mostly at the ridge and along the fracture zones. The thin, black, numbered lines are age contours in million years from the present. The black dots are earthquakes. Larger magnitude earthquakes are marked in red stars. The various coloured symbols indicate deployment sites. Green checked marks are the current completed sites.
