Abstract
We show first results from the German licence areas in the Central and SE Indian Ridge obtained with GOLDEN EYE, a new deep-sea electromagnetic system, for seafloor massive sulfide exploration. Golden Eye has been developed by the Marine Geophysics Group of University of Bremen by order of and in cooperation with BGR. The system consists of a non-magnetic and non-conductive frame made from glasfibre inforced plastic, and holds the CSEM Loop system, a current transmitter and electrical source and receiveing dipoles for DC and IP measurements, a three-axial broadband magnetometer, a CTD sensor, and video cameras, LEDs and altimeter for secure navigation.
During the INDEX 2015 cruise the system was deployed over previously known active and inactive fields. First analysis of data show a clear correlation between anomalous conductivities and chargebilities, and SMS sites.
