Instruments | SUESI

Scripps Undersea Electromagnetic Source Instrument

A horizontal electric dipole EM transmitter for CSEM sounding. Output current is up to 500 amps on a neutrally buoyant antenna up to 300 m long, for a source dipole moment up to 150 kAm. SUESI is designed to be portable, using the UNOLS standard .680" coaxial deeptow cable. A combination of acoustic altimeters, long baseline acoustic navigation, depth gauge, and sound velocity meters is used to navigate SUESI's position. Scripps currently owns two completely redundant SUESI-500 systems.
