The SeaSpy Marine Magnetometer is made by Marine Magnetics, of Ontario, Canada.
It utilizes a branch of nuclear magnetic resonance imaging known as the “Overhauser”
effect to produce an omni-directional measure of the local magnetic field.
It can be operated in stand-alone mode with its own software, or can be set to communicate
both data and control over a single RS-232 serial link.
OIC supports the SeaSpy both as an independent sensor, using GeoDAS-LT for a complete
control and display topside, or in conjunction with another sensor such as a sidescan,
in GeoDAS-PC.
