Our client GreenReef LCC (Marine Geodesy company group) recently purchased a 15 sensor MX3D UW magnetometer system. The Russian company set up an 8 meter wide ROV frame to install 10 sensors in front of their ROV. At the moment the system is operated offshore on the Baltic Sea. the MX3D UW consists of triaxial Fluxgate Magnetometer sampled with 200Hz providing not only total field values, but single axis measurement values as well. The SENSYS recording software MonMX Marine is storing all data and provides the raw data for interpretation within SENSYS software MAGNETO or third party software like GeoSoft.
