CDEX/JAMSTEC checks the recovery and quality of all core samples collected by D/V Chikyu. A medical-grade X-ray CT scanner aboard ship allows scientists to quickly identify and preserve important geological structures for later analysis.
It is CDEX/JAMSTEC policy to continuously improve both core recovery and quality through the development of new sampling tools and techniques. This includes careful analysis of drilling parameters and suggestions for new procedures during coring operations.
- CT images used to analyze core sample quality.
- Analyze drilling parameters and ship motion for factors affecting core recovery.
- Develop new coring bits to improve recovery rates and quality of core samples.
