GHMT Logging Runs

Two passes (upper and lower section) were recorded. The quality of the data is particularly poor; the magnetic susceptibility sonde (SUMS) experienced intermittent malfunction during the entire recording. In addition, the repeatability of the logs recorded with the Nuclear Resonance Magnetometer Tool (NMRS) is not satisfying and therefore no processing has been performed.

Additional information about the logs can be found in the "Explanatory Notes" and Site Chapter, ODP IR volume 165. For further questions about the logs, please contact:
