Treasure Chest of Cores
From the first drill site of the Deep Sea Drilling Project back in 1968, through cores recovered during the Ocean Drilling Program between 1985 and 2003, to the cores recovered on the JOIDES Resolution last week for the Integrated Ocean Drilling Program, the combined ocean drilling programs have recovered more than 56,000 cores. That's a lot of rock and sediment. But, more importantly, these cores represent a treasure chest of scientific knowledge, filled with information about Earth's history, structure, and processes. All 56,000 cores have been tested, sampled, studied, examined, and dissected to get every possible ounce of scientific data out of them. Each core provides a key to unlock part of that giant treasure chest, and scientists who study the cores are continually finding new keys to see what the treasure chest will reveal next. The six cores listed below represent some of the most amazing discoveries in the history of the ocean drilling programs.
