The Alaskan and northern Canadian Cordillera, stretching from British Columbia and southeast Alaska to the Beaufort, Chukchi, and Bering Seas, is a seismogenic region consisting of accreted terranes and large-offset faults, long-lived subduction, past and present magmatism, multiple orogenic episodes, and a mantle with an array of inherited structures and striking velocity variations. Recent studies in the area as well as large-scale networks (e.g. USArray, NOTA) have generated new data sets and results and the region has been identified as having world-class science questions to be targeted by future multidisciplinary/multi-sensor arrays. We welcome contributions on the geology, geochemistry, geophysics, petrology, and tectonics of the region (including the subduction zone and volcanic arc), and encourage reports from the many recent and ongoing studies as well as integrative summaries of the region.
