| Please note that the system can only be operated upon request. Operations with the MSCL-S requires experienced scientific staff on board. The system is not operated by the ship's crew. Announce operations with the MSCL-S to AWI-Logistics prior to the cruise and clarify the data transfer after the cruise. |

The system consits of the measuring bench with a ballscrew, which pushes core section past 6 to 7 sensors measuring Gamma Density, P-wave Velocity, Magnetic Susceptibility, Point Magnetic Susceptibility, Colour Spectrophotometry, Linescan Imaging and optional Natural Gamma Spectrometry. All sensors simultaneously acquire the data, which is displayed real-time during logging. The acquired data is stored locally in the electronics with simple user interface. |
