EM Lab completes survey of Alaskan Subduction Zone

This has been a year for subduction zone electromagnetic surveys. In February we completed a large-scale survey of the Hikurangi Trench off the North Island of New Zealand, and now we just completed a complementary large-scale survey of the Alaskan subduction zone. Principal investigators Kerry Key and Samer Naif led  a large team that included Lamont graduate students Christine Chesley and Tanner Acquisto and postdoc Julen Alvarez-Aramberri  onboard the R/V Sikuliaq offshore of the Alaska Peninsula.  The electromagnetic and magnetotelluric imaging data collected using 159 seafloor stations and a deep-towed transmitter will be used to study fluids along the subduction zone plate boundary and how they impact plate tectonics and seismicity.
