Over five years, engineers had designed, built, and tested components for a new, one-of-a-kind system to extend the length of sediment samples cored from the seafloor. In September 2007, they took it to sea to find out if the new coring system installed on the research vessel Knorr could accomplish the daunting feat of pulling up cores weighing up to 30,000 pounds and measuring up to 45 meters (150 feet).

That nearly doubles the United States research fleet's coring capacity, which had ranged from 20 to 25 meters (60 to 80 feet). The longer the cores, the deeper they go, collecting older sediments that record past ...
