Attention:
Please note that Core Loggers (MSCL) can only be operated upon request. Operations with Core Loggers requires experienced scientific staff on board. The system is not operated by the ship's crew. Announce operations with the Core Loggers to AWI-Geology and AWI-Logistics prior to the cruise and clarify the data transfer after the cruise.
Summary
Core Loggers capture physical measurands of sediment cores. AWI holds different Geotek Ltd. Core Loggers with different sensor set-ups. Maximum 3 Core Loggers can be stored and operated on FS Polarstern.
Manufacturer: Geotek Ltd.
Model: MSCL-S
Serial No:
Type: Multi-Sensor Core Logger
Responsible Persons
| Role | Name |
|---|---|
| Engineer in Charge | Dietmar Penshorn |
| Data Scientist | Frank Niessen |
Components
The system consits of the measuring bench with a ballscrew, which pushes core section past the 9 sensors (Gamma Density, P-wave Velocity, Magnetic Susceptibility, Non-Contact Resistivity, Colour Spectrophotometry, Geoscan V Linescan Imaging, Natural Gamma Spectrometry, Near-infrared/Visible Spectrophotometry, X-ray Fluorescence). 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.
