|
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 gravitationThe LaCoste and Romberg gravity meter is used for tying of the data of marine gravity meter KSS 32 M into the international standard gravity network. It is small and portable and can therefore be used to measure relative gravity at absolute gravity points on land during port calls. |
