EM Lab completes deep tow operations in extensive survey of the Hikurangi Trench off New Zealand

PI Samer Naif led a large team that included Lamont graduate students Christine Chesley, Bar Oryan, and Daniel Blatter onboard the R/V Roger Revelle in the waters east of North Island, New Zealand to carry out a marine electromagnetic (EM) survey of the Hikurangi subduction zone. The project includes over 168 seafloor EM receiver stations and over 400 line-km of transmitter deep-tow tows, making it the largest marine EM experiment at a subduction zone yet.  The data will allow the team to assess the role that fluids play in both generating subduction zone earthquakes, and in controlling the seismic behavior of faults more generally.
