Summary of measurements |
- -Systematic surveying of magnetism (proton magnetometer and three component magnetometer at surface), gravity and bathymetry (Thomson multibeam echosounder).
-TOBI survey in 3 boxes, 2 along the South-west Indian ridge (Boxes 1 and 2) and 1 perpendicular to the axis (Box 1). -Systematic measurements taken of water turbidity using nephelometers attached to the TOBI cable, in order to show any presence of hydrothermal plumes in the water column. -Seismic refraction experiment with 10 OBS to determine the crustal structure. -Natural seismicity experiment with 10 OBS to locate seismic events.
