Investigate the effects of this rapid shoaling of the axial magma chamber on the fine-scale volcanic, hydrothermal and tectonic characteristics and behavior of the axial zone of the ultrafast spreading EPR at 17-18 degrees south. Sensors include the AMS-120 sonar system, the ARGO camera system and tow-yo CTD/nephelometer. Dozens of black smoker hydrothermal vents were discovered.
