Attention:
Please note that the Magnetometer System can only be operated upon request. Request operations with the Magnetometer System to AWI-Logistics in sufficient time prior to the cruise.
Summary
Magnetometers are used to measure the earth magnetic field. The magnetometer on board of Polarstern is a vector magnetometer that measures the vector components of the magnetic field. It consists of an upper and a lower sensor.
