Expedition 340 was designed to give us a better understanding of the constructive and destructive processes related to volcanism along island arcs. Michael Manga also had the opportunity to study heat flow on this cruise. Heat flow above and adjacent to this volcanic arc is similar to that of continental volcanic arcs.
The Physical Properties specialists. No flipflops while working. Notice the small radiation dosimeter.
2 mud clasts, 1 piece of pumice embedded in a volcaniclastic turbidite.
Measuring density, magnetic susceptibility and p-wave speed.
Measuring natural gamma ray emission.
