Protocols for core handling, description, and archiving:
Secrets of successful scientific drilling projects
LacCore (National Lacustrine Core Facility)

June 2010 CSD Workshop
I got my core!!
Do I know exactly where it came from? Do I know which way is up?
Is it a high quality core?
How do I get it home?
How do I find the time for the ICD?
June 2010 CSD Workshop
• Core handling at the drill site
• Core handling during initial core description
• Sampling cores
• Sharing information amongst PI groups
• Archiving cores and associated data
• Sharing information and samples with others

Plan!
June 2010 CSD Workshop
• Scientists want 100% recovery with little to no deformation
• Driller want to drill deeper fast
Interpreter betw. PIs & drillers
June 2010 CSD Workshop
Drillers want to drill deeper fast
• Incorrect tools for scientific drilling
• Interpretation of recovery
• Depth marks and # of pipes
• Drilling errors
– HPC still in the hole?
– Mud or water?

Preventing degradation of cores and
loss of information
during shipping•Close gaps
•Seal tightly
•Keep cold

ICD takes ~forever• Many GLAD projects have failed to
complete the ICD within the 2-year proprietary period.
• Cores remain unopened and undescribed
disputes over sample access,
friction among the science groups,
delayed publication of results
