Past the half-way mark

Out of 39 sites 20 are complete with the ocean bottom stations already recording data.

After 11 days at sea we have passed the halfway mark, i.e., deployed half of the intended stations. Deployments are now proceeding smoother than we have started. We have all become familiar with the procedure of putting an instrument into the water, and it has become a well-timed routine. Out of 39 sites, 20 are complete with the ocean bottom stations already recording data, and will remain there for next couple of months.

Here is a map of 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.
