3D MCS investigation of the East Pacific Rise 9° 50’N

In summer 2008 we conducted the first multi-streamer Multi-Channel Seismic program of Lamont’s new national marine seismic facility, the R/V Langseth. The goals of our experiment are to create an accurate 3D seismic reflection image of the magmatic-hydrothermal system at the fast spreading East Pacific Rise 9°50’N by imaging the structure of the axial magma chamber (AMC) lid, shallow oceanic crust, and Moho at a resolution, geometric accuracy, and scale comparable to seafloor observations of hydrothermal, biological, and volcanic activity.
