This one-page guide to cores explains what they are, where they come from, and how IODP keeps them all organized (we've collected a lot, so we needed a good system).

Have you ever wondered how we are able to process so many cores in so little time? The core-flow process is a refined system for moving cores from the drill pipe and into the labs. This presentation shows the core-flow process in pictures.  For more about the core flow process, see chapters IV through VII in the Core Lab Cookbook, below.

Just like you need recipes to prepare a fine meal, you need recipes to analyze a core. The Core Lab Cookbook describes the procedures and processes that routinely take place in the core lab.

One Core at a Time< - Learn about the significance and importance of recovering cores from the seafloor.

The Life of a Core< - Find out how cores are recovered and analyzed aboard the JOIDES Resolution.

Drilling Through Time< (PDF, 71 KB) - How old are the cores that the JOIDES Resolution has recovered?
