 The project drilled Detroit, Nintoku, and Koko seamounts, all in the far northwest of the chain.Detroit Seamount was drilled twice (numbered 1203 and 1204), on the summit and on one of its secondary cones; care was taken to put the locations away from major fault lines or other geological features that would otherwise invalidate or bias the results.In 2005 it underwent a detailed geological analysis by scientists from Stanford University.
