Marine Magnetics SeaSPY


SeaSPY sensors are highly accurate and repeatable, making them ideal for gradiometers. SeaSPY’s mandate was to help surveyors save time, money and energy, by taking the realities of field-work into account.

A magnetic gradiometer measures magnetic gradient in one dimension by subtracting the difference between two independent magnetic sensors. Since the Earth’s magnetic field is three dimensional, up to three independent gradient directions can be measured – vertical, horizontal (across-track) and longitudinal (along-track).

Marine Magnetics offers each of these gradiometer configurations. In addition, all SeaSPY magnetometers are compatible, enabling existing SeaSPY customers to upgrade their magnetometer to the gradiometer configuration of their choice, as they need to.
