Please note that the Marine Gravitymeter System can only be operated upon request. Request operations with the Marine Gravitymeter System to AWI-Logistics in sufficient time prior to the cruise. |
A gravimeter is used to measure accelerations due to the gravitational field of the earth. The gravimeter on board of Polarstern is situated on a gyro-stabilized platform to compensate for the ship's movement. It is a spring and mass system with magnetic compensation, the extension of the spring being proportional to the gravitational force. |

The Marine Gravitymeter System consits of the Gravitymeter KSS 32-M and the operator-laptop in the Gravitymeter Room on board. The Gravitymeter control system and data acquisition software BGGS DACQS is installed on the laptop. |
