In December 2010, an international team of scientists set sail in the South Pacific on the research drilling vessel JOIDES Resolution on an eight- week expedition along the 4300 km long Louisville seamount trail.  The objective: to better understand the movement  and evolution of the hotspot that created this chain of underwater volcanoes. The JR drilled for cores at five different sites at depths of up to 1840 meters (6037 feet)! The data collected will be compared with the better studied Hawaiian island-Emperor seamount trail to help determine if the chains of volcanoes created by hotspots are a result solely of the movement of the tectonic plate above the hotspot, or if the hotspots are also moving within the mantle. The core data will also be used to see if the chemical makeup of the rocks in the seamounts and guyots is consistent across the Louisville seamount chain, or if the geochemistry of these volcanic rocks changes as the hotspot ages.

 So, How Do I Learn More?

Easy! Check out the Blog<s from the expedition to learn about the scientists onboard and find out what they were doing on the expedition  (links to the Expedition 330 bloggers can be found at the bottom of this page) . To read the daily science reports and blogs of co-chief scientist  Anthony Koppers, visit his Expedition 330 website<. To see photos, visit the online photo album of the expedition<

The scientists conducted 30 videoconferences with schools and museums. To read an article about one of these, click here<.
