| Definition | A marine magnetometer that measures the ambient magnetic field using a specialised branch of nuclear Magnetic Resonance technology applied to hydrogen nuclei. It uses an Overhauser sensor that allows omnidirectional data collection regardless of the direction of the ambient magnetic field. The sensor is accurate to 0.1 nT with a resolution of 0.01 nT. The magnetometer and associated electronics are held in a fibreglass towfish and the SeaSPY is available in three depth ratings: 1000 m, 3000 m and 6000 m. Optional extras include a pressure sensor, altimeter, transponder and side scan integration. | |
