Preliminary scientific assessment

Expedition 321T included only cementing operations. No scientific data or samples were collected. Researchers will visit the two CORKs in August 2009 with the submersible Alvin to download data, determine if the observatories are now sealed, and replace downhole instrument strings in preparation for completing the full suite of interdisciplinary experiments.

Expedition 321T completed all planned operations more quickly and with less difficulty than had been anticipated. We were fortunate to have excellent weather and sea conditions; this is an area where working conditions can be poor, even during an optimal weather window. In addition, we benefited from the experience, advice, skill, and patience of the ship and rig crews and officers, especially the dynamic positioning system operators, cementing personnel, and drillers. Even under optimal weather and sea conditions, this was a delicate and challenging set of operations. We were fortunate to sail with such a capable and dedicated crew.
