contenttypeSummary

A gravimeter is used to measure the gravitational field of the earth. The gravimeter on board of Polarstern is situated on a gyro-stabilized platform to compensate for the ships movement. It is a spring and mass system with magnetic compensation, the length of the spring being proportional to the gravitation.
